Questions and answers

It depends on the plant and how many emitters it gets. For containers, DIG suggests one or two 0.5 GPH drippers per pot as a starting point; check the soil and adjust. See emitter flow and inlets. More in Drip emitters: flow, pressure range and inlet

They help on long runs and slopes, but only inside their range. A 2019 study's abstract says PC emitters give constant flow above the lower limit of their range and orifice-type flow below it. DIG's PC buttons compensate from 7.25 to 58 psi. More in Drip emitters: flow, pressure range and inlet

DIG recommends keeping drippers above ground or under mulch to prevent clogging, rather than burying them. More in Drip emitters: flow, pressure range and inlet

Check the filter and the pressure first, then look for clogged or buried emitters and long 1/4 in runs. The troubleshooting guide lists the checks. More in Drip emitters: flow, pressure range and inlet

Start from the plant and soil, then check the pressure range. DIG suggests one or two 0.5 GPH drippers per pot, and Utah State University Extension suggests two emitters per perennial in sandy soil. More in 0.5, 1, 2 or 4 GPH: drip emitter flow, color codes and inlets

Each maker uses its own code. Raindrip uses red for 0.5 GPH, black for 1, green for 2 and yellow for 4, but DIG's 0.5 GPH button is brown and its 0.5 GPH inline emitter is red, so read the maker's page for the model. More in 0.5, 1, 2 or 4 GPH: drip emitter flow, color codes and inlets

The total flow is the same by arithmetic, but two emitters wet two spots. Utah State University Extension suggests two emitters per perennial in sandy soil, where water moves straight down. More in 0.5, 1, 2 or 4 GPH: drip emitter flow, color codes and inlets

An emitter with a small threaded inlet that screws into a 10-32 riser or adapter instead of pushing onto a barb. Rain Bird sells its Xeri-Bug in barb, 10-32 and 1/2 in FPT inlet versions. More in 0.5, 1, 2 or 4 GPH: drip emitter flow, color codes and inlets

Only at the pressure the maker rates it at, unless it is pressure-compensating and your pressure is inside its range. DIG says the flow of its inline emitters depends on the inlet pressure. More in 0.5, 1, 2 or 4 GPH: drip emitter flow, color codes and inlets

No source gives a fixed number. Utah State University Extension says to spread emitters evenly within the drip line and to design for the mature tree in the hottest part of the year. More in Drip emitters for trees and shrubs: placement, flow and bubblers

Above ground, spread evenly within the tree's drip line, per Utah State University Extension. DIG also recommends keeping drippers above ground or under mulch. More in Drip emitters for trees and shrubs: placement, flow and bubblers

A bubbler puts out much more water at one point; Rain Bird's 1300A-F is rated 1.0 to 2.3 GPM. Keep bubblers on their own line, since Raindrip says never to mix drippers and sprinklers on one line. More in Drip emitters for trees and shrubs: placement, flow and bubblers

DIG suggests conventional pop-up sprinklers for lawns, not micro sprinklers or drippers. More in Drip emitters for trees and shrubs: placement, flow and bubblers

DIG says it depends on location, plants, soil and weather, and advises checking the soil and plants and adjusting. We give no schedule. More in Drip emitters for trees and shrubs: placement, flow and bubblers

If all emitters are weak, clean the filter and check the pressure; DIG says most drip systems work best at 20 to 50 psi. If one is dry, it is probably clogged or buried. More in Drip emitters not dripping or uneven: what to check

Pressure drops along the tubing, more so in 1/4 in tubing than in 1/2 in, as a Utah State University Extension presentation illustrates. Shorten long 1/4 in branches or feed them closer to the plants. More in Drip emitters not dripping or uneven: what to check

Flush with water: rinse the filter under running water and open the mainline ends during a manual run, as DIG describes. We do not cover chemical cleaners; replace an emitter that stays blocked. More in Drip emitters not dripping or uneven: what to check

Yes. Rain Bird calls its PC on-line emitters self-flushing and still recommends 200 mesh filtration. More in Drip emitters not dripping or uneven: what to check

Run 1/4 in tubing from a supply line to each pot, end each branch at a dripper on the soil surface, and group pots by sun or shade, as DIG suggests. More in Drip for pots and hanging baskets: emitters, 1/4 in tubing and stakes

DIG suggests one or two 0.5 GPH drippers per pot as a starting point. Check the soil and plants and adjust the watering time. More in Drip for pots and hanging baskets: emitters, 1/4 in tubing and stakes

Mister Landscaper says its system is not for indoor use and its regulators should not be used anywhere a leak might damage something. On a balcony, check the system often and never leave it unwatched. More in Drip for pots and hanging baskets: emitters, 1/4 in tubing and stakes

Raindrip says never mix drippers and sprinklers on the same line, because their flow rates differ. Run sprays on their own line. More in Drip for pots and hanging baskets: emitters, 1/4 in tubing and stakes

No. DIG recommends keeping drippers above ground or under mulch to prevent clogging. More in Drip for pots and hanging baskets: emitters, 1/4 in tubing and stakes

They hold their rated flow only inside their stated range. A 2004 study found both compensating types within plus or minus 10% of rated flow but only one of seven non-compensating types; it was a regional sample, not a ranking of today's products. More in Pressure-compensating vs non-PC drip emitters: what the ratings and studies say

Only down to the bottom of their range. A 2019 study's abstract describes PC emitters as giving orifice-type flow below the lower limit of their compensating range. More in Pressure-compensating vs non-PC drip emitters: what the ratings and studies say

No source we found gives a slope rule. A PC emitter holds its flow only while the pressure at that emitter stays inside the range its maker lists, such as 7.25 to 58 PSI for DIG's PC buttons. More in Pressure-compensating vs non-PC drip emitters: what the ratings and studies say

Utah State University Extension lists eight common causes: pressure variation, manufacturing variation, spacing, disrepair, clogging, weather, irrigation duration and soil infiltration. Check filters and pressure first. More in Pressure-compensating vs non-PC drip emitters: what the ratings and studies say

Not by default. DIG's adjustable mini-bubbler turns from full flow to shut-off, and DIG does not call it pressure-compensating. More in Pressure-compensating vs non-PC drip emitters: what the ratings and studies say

It is the pressure range over which DIG says these emitters compensate. A 2019 study's abstract describes PC emitters as giving constant flow above the lower limit of their range and orifice-type flow below it. More in Drip emitters with a stated flow and pressure range

No. DIG's standard buttons come in .5, 1 and 2 GPH and are rated for 15 to 25 psi, with flow that rises with pressure. More in Drip emitters with a stated flow and pressure range

DIG recommends keeping drippers above ground or under mulch to prevent clogging, rather than burying them. More in Drip emitters with a stated flow and pressure range

Tubing with emitters built in at a fixed spacing, laid along a row or through a bed. Rain Bird XFD, for example, comes with 0.6 or 0.9 GPH emitters at 12 or 18 in spacing. More in Drip line: flow, spacing, pressure and run length

As long as its maker's table allows at your pressure, which is much shorter than the coil. Rain Bird allows 273 ft of 0.6 GPH, 12 in XFD at 15 psi and 460 ft at 60 psi; DIG limits a single 6 in Microline run to about 16 ft at 25 psi. More in Drip line: flow, spacing, pressure and run length

Rain Bird specifies its XF dripline insert fittings or its Easy-Fit compression fittings for XFD. More in Drip line: flow, spacing, pressure and run length

Some does, some does not. Netafim says Techline CV has a check valve that keeps water in the line after shut-down. Rain Bird's XFD page mentions no check valve; Rain Bird offers that in a separate model, XFCV. More in Drip line: flow, spacing, pressure and run length

As long as its maker's table allows for your spacing, flow and inlet pressure. Rain Bird's XFD table gives 273 ft at 15 psi and 460 ft at 60 psi for 0.6 GPH at 12 inch spacing. More in Drip line spacing and maximum run length: read the maker's table

For DIG Microline, about 16 ft at 6 inch spacing, 22 ft at 9 inch and 28 ft at 12 inch, at 25 psi on level ground. Other 1/4 in lines need their own maker's figure. More in Drip line spacing and maximum run length: read the maker's table

Yes. Closer spacing puts more emitters on each foot, so DIG's Microline limit drops from 28 ft at 12 inch spacing to 16 ft at 6 inch. More in Drip line spacing and maximum run length: read the maker's table

Not per DIG's table for Microline, which tops out at about 28 ft per run at 25 psi. Cut the coil into several runs fed from a 1/2 in supply line. More in Drip line spacing and maximum run length: read the maker's table

Drip line suits a densely planted bed because the emitters are already spaced along it; DIG's ML50 raised-bed kit, for example, has emitters every 9 inches. Loose emitters suit plants spaced far apart. More in Drip line, loose emitters or micro-sprays for a bed or row

In one garden, yes, but not on one line. Colorado State University Extension advises a separate zone for micro-sprays, and Raindrip says never to mix drippers and sprinklers on the same line. More in Drip line, loose emitters or micro-sprays for a bed or row

Makers offer 6 to 24 inch spacing, and no source sets a spacing by plant. CSU gives soil-based guidance of about 12 inches in sand, 18 in loam and 24 in clay. More in Drip line, loose emitters or micro-sprays for a bed or row

Colorado State University Extension advises irrigating when the top two to four inches of soil feel dry. More in Drip line, loose emitters or micro-sprays for a bed or row

No. A soaker hose seeps through its porous wall along its length; drip line has emitters at a fixed spacing. Raindrip lists its soaker hose as a separate product from its dripline. More in Soaker hose vs drip line: porous tubing vs fixed emitters

For Raindrip's soaker tubing, under 15 feet; its FAQ warns that longer runs water unevenly. Other makers' soaker hoses need their own figure. More in Soaker hose vs drip line: porous tubing vs fixed emitters

Raindrip says its 1/4 in soaker tubing connects with a 1/4 in micro fitting or a Clamp N Pierce connector. Give it its own branch. More in Soaker hose vs drip line: porous tubing vs fixed emitters

Raindrip says its 015005T is not, and that its flow varies with length and elevation, higher near the source. More in Soaker hose vs drip line: porous tubing vs fixed emitters

Because DIG limits a single Microline run at 25 psi on level ground to about 16 ft at 6 in spacing, 22 ft at 9 in and 28 ft at 12 in. Cut the coil into several runs. More in Drip line with published flow, spacing and run tables

Rain Bird's XFD page does not mention a check valve; Rain Bird offers that feature in a separate model, XFCV. More in Drip line with published flow, spacing and run tables

Netafim publishes its flow, spacing and range, but no Techline CV listing is in our approved catalog yet. We do not add products we have not approved. More in Drip line with published flow, spacing and run tables

Usually a backflow device, a filter, a pressure regulator and an adapter to your tubing. The order depends on your kit maker; see the faucet head assembly guide. More in Drip faucet head assembly

Follow your kit maker. Mister Landscaper's order from the faucet is backflow device, timer, regulator, 150 mesh filter, then the poly fitting, for its own system. Other makers differ, and we found no universal order. More in Drip faucet head assembly

Ask your water utility or local plumbing authority. The EPA says backflow prevention programs vary by state and municipality; DIG notes that some municipalities and water districts require such devices. More in Drip faucet head assembly

Usually because one is hose thread and the other pipe thread. Raindrip says to match hose thread to hose thread and pipe thread to pipe thread; mismatched threads are the main cause of leaks. More in Drip faucet head assembly

Yes, with a kit made for your head. Rain Bird's 1800-RETRO, for example, drops into an existing Rain Bird 1804 spray body and includes a 30 psi regulator and a 200 mesh screen. More in Convert a sprinkler zone to drip: retrofit kits by spray body and riser

No. Each kit names its interface, and Rain Bird's CNV182EMT even lists 1802 and 1803 bodies it excludes. More in Convert a sprinkler zone to drip: retrofit kits by spray body and riser

Use the one the kit includes. Rain Bird's 1800-RETRO, Riser Connection Kit and CNV182EMT each list a 30 psi regulator. More in Convert a sprinkler zone to drip: retrofit kits by spray body and riser

DIG suggests conventional pop-up sprinklers for lawns, not micro sprinklers or drippers. More in Convert a sprinkler zone to drip: retrofit kits by spray body and riser

Your kit maker's order. Mister Landscaper lists backflow device, timer, regulator, 150 mesh filter, then poly fitting for its system; we found no source that sets one order for every brand. More in Drip faucet head assembly: the parts, the threads and the maker's order

It depends on the maker. Mister Landscaper puts the regulator before the filter, and DIG's D54 combines both in one body. More in Drip faucet head assembly: the parts, the threads and the maker's order

Mister Landscaper says its backflow prevention valve has relief holes and that some water draining from them is normal. For other devices, check the maker's instructions. More in Drip faucet head assembly: the parts, the threads and the maker's order

Not every regulator. DIG says its D54 must not be under constant static pressure, and Rain Bird recommends taking head parts indoors for winter. More in Drip faucet head assembly: the parts, the threads and the maker's order

Your water utility or local plumbing authority. The EPA says programs vary by state and municipality. More in Drip faucet head assembly: the parts, the threads and the maker's order

The mesh your emitters' maker asks for. Utah State University Extension says most drip systems need 120 to 200 mesh, and Clemson says at least 150. More in Drip filter mesh: 150 vs 200 and what your emitters ask for

It is finer: about 0.074 mm openings against about 0.100 mm. Match what the emitter maker asks for; Rain Bird asks for 200 mesh on its PC on-line emitters and 120 on XFD. More in Drip filter mesh: 150 vs 200 and what your emitters ask for

Utah State University Extension recommends inspecting and cleaning filters monthly in the growing season, more often with sediment-heavy water. DIG says to clean it under running water. More in Drip filter mesh: 150 vs 200 and what your emitters ask for

Yes. Colorado State University Extension's 150 to 200 mesh guidance is for relatively clean municipal water; well or pond water needs more. More in Drip filter mesh: 150 vs 200 and what your emitters ask for

Rain Bird calls its PC on-line emitters self-flushing and still asks for 200 mesh filtration. More in Drip filter mesh: 150 vs 200 and what your emitters ask for

Your water utility or local plumbing authority decides. The EPA says cross-connections can occur between public water systems and private irrigation systems, and that prevention programs vary by state and municipality. More in Backflow preventers on a drip faucet: what they are and who decides

Ask your water utility; we do not decide. ASSE lists a standard for hose connection vacuum breakers (1011-2023) and one for hose connection backflow preventers (1052-2023), but local rules set which applies. More in Backflow preventers on a drip faucet: what they are and who decides

Some devices release water by design. Mister Landscaper says its valve's relief holes drain some water normally; for other devices, check the maker's instructions, and do not block vents or drains. More in Backflow preventers on a drip faucet: what they are and who decides

Start with your water utility. The EPA also points to state drinking water programs, plumbing or building code authorities and health departments. More in Backflow preventers on a drip faucet: what they are and who decides

Usually. DIG says most drip systems work best between 20 and 50 psi and names high pressure as the typical reason a drip system functions improperly. More in Drip pressure regulators: outlet PSI, flow range and static pressure

One inside the range of every part downstream. Makers sell drip regulators at outlet pressures such as 25 PSI (DIG D54) and 30 psi (Rain Bird PRF07530SX). More in Drip pressure regulators: outlet PSI, flow range and static pressure

With no flow, inlet pressure can equalize across a standard regulator, Senninger explains. Read the gauge with the zone running. More in Drip pressure regulators: outlet PSI, flow range and static pressure

Only if your total flow reaches its minimum. Rain Bird's 3/4 in RBY, for example, is rated for 0.20 to 5.0 gpm. More in Drip pressure regulators: outlet PSI, flow range and static pressure

Senninger recommends at least 5 psi more at the inlet than the expected outlet pressure, for its regulators. More in Drip pressure regulators: outlet PSI, flow range and static pressure

FHT is female hose thread and FPT is female pipe thread. They follow different standards, ASME B1.20.7 for hose threads and B1.20.1 for pipe threads. More in FHT, MHT, FPT and MPT: hose thread vs pipe thread on drip parts

Not as a sound joint. Raindrip advises matching hose thread to hose thread and pipe thread to pipe thread; use an adapter such as DIG's 50007 (3/4 in FHT to 3/4 in MNPT). More in FHT, MHT, FPT and MPT: hose thread vs pipe thread on drip parts

Male hose thread: threads on the outside of a hose-thread part. DIG's D45, for example, has a 3/4 in MHT outlet. More in FHT, MHT, FPT and MPT: hose thread vs pipe thread on drip parts

No source we read covers it. Follow the maker's instructions; Raindrip, for its own parts, puts the filter washer inside the faucet connection. More in FHT, MHT, FPT and MPT: hose thread vs pipe thread on drip parts

We do not say any device meets code. The EPA says backflow programs vary by state and municipality; ask your water utility or local plumbing authority what your faucet needs. More in Faucet head parts with stated threads, mesh and pressure

Not directly. Raindrip says to match hose thread to hose thread and pipe thread to pipe thread; use an adapter made for the pair. See the thread guide. More in Faucet head parts with stated threads, mesh and pressure

Your kit maker's order. Mister Landscaper's, for its own system, is backflow device, timer, regulator, 150 mesh filter, then the poly fitting. There is no universal order. More in Faucet head parts with stated threads, mesh and pressure

Fittings whose maker lists your tubing's OD. DIG's black-insert fittings are for .700 in OD and its blue-insert fittings for .710 in OD; Rain Bird's Easy-Fit is listed for 0.63-0.70 in OD. See how to measure drip tubing. More in Drip mainline fittings, by tubing OD

No. Each covers the range its maker states. Orbit's 67466 is listed for .620-.710 in OD, DIG's NUTLOC for .630-.710 in OD, and Rain Bird's Easy-Fit for 0.63-0.70 in OD. More in Drip mainline fittings, by tubing OD

Locking-nut fittings are made to come apart: Orbit says you loosen the 67466 nut to remove the tubing, and Mister Landscaper calls its MLF fittings reusable. More in Drip mainline fittings, by tubing OD

On DIG fittings, the insert color marks the tubing OD: green for .620-.630 in, black for .700 in and blue for .710 in. That mapping is DIG's; other makers may use other colors. More in Drip mainline fittings, by tubing OD

Orbit lists the 67466 for .620-.710 in OD and Raindrip lists Smart Loc S5600UB for .620 x .710 in tubing. Rain Bird lists Easy-Fit for 0.63-0.70 in OD, so .710 in is outside its range. More in Orbit 67466 vs Raindrip Smart Loc vs Rain Bird Easy-Fit coupling

T63 is 0.63 in OD. That is inside Orbit's .620-.710 in range and at the bottom of Easy-Fit's 0.63-0.70 in range. Raindrip lists .620 in OD, not 0.63, so ask Raindrip before using Smart Loc on T63. More in Orbit 67466 vs Raindrip Smart Loc vs Rain Bird Easy-Fit coupling

Rain Bird lists Easy-Fit at 0 to 60 psi and Raindrip says Smart Loc S5600UB handles up to 50 psi. We found no pressure rating on Orbit's 67466 page. More in Orbit 67466 vs Raindrip Smart Loc vs Rain Bird Easy-Fit coupling

Orbit says the 67466 is reusable: loosen the nut to remove the tubing. Raindrip and Rain Bird do not state reuse on the pages we read. More in Orbit 67466 vs Raindrip Smart Loc vs Rain Bird Easy-Fit coupling

Neither in general. A compression fitting is sized by the tube's outside diameter and a barbed insert by its inside diameter or a metric family, so choose the type your tubing's documented size supports. More in Compression, barbed or locking-nut drip fittings: how each one grips

A fitting with a barb that goes inside the tube and a nut or collar that tightens over the outside. Raindrip's Smart Loc secures with a barb and twist-on nut, and Orbit's 67466 locks with a hand-twisted outer nut. More in Compression, barbed or locking-nut drip fittings: how each one grips

Only where the maker says so. Orbit says the 67466 coupling is reusable by loosening its nut, and Mister Landscaper calls its MLF locking-collar fittings reusable. More in Compression, barbed or locking-nut drip fittings: how each one grips

Not Perma-Loc ones, according to Drip Depot, which says Perma-Loc fittings for drip tape and for poly tubing are not interchangeable. More in Compression, barbed or locking-nut drip fittings: how each one grips

On DIG's compression fittings, the insert color marks the tubing OD: green for .620-.630 in, black for .700 in and blue for .710 in. That is DIG's code; other makers use colors differently. More in Green, black or blue? DIG compression inserts by tubing OD

Only on DIG's listing, where green is for .620-.630 in OD. Raindrip, for example, uses green to mark a 2 GPH dripper, not a fitting size. More in Green, black or blue? DIG compression inserts by tubing OD

DIG lists its blue insert for .710 in OD tubing and its black insert for .700 in OD, so use blue (C43, C45, C46) for .710 in tubing. More in Green, black or blue? DIG compression inserts by tubing OD

DIG rates them for up to 60 PSI and recommends operating them at 15 to 35 PSI. More in Green, black or blue? DIG compression inserts by tubing OD

Use a closure made for its size: an end cap whose maker lists your OD, such as Orbit's 67468 for .620-.710 in OD, or a figure-8 closure. For 1/4 in tubing, a goof plug or a 1/4 in tubing plug. More in Drip tubing end caps, figure-8 closures and flush points

A figure-8 shaped piece that holds the folded-back end of the tubing shut. Rain Bird's winter guide removes figure-8 end caps to drain a line and puts them back loosely, because they only protect the line. More in Drip tubing end caps, figure-8 closures and flush points

DIG says to open the ends of the mainlines and flush them during a manual run. Close them again once the water runs clear. More in Drip tubing end caps, figure-8 closures and flush points

DIG says its goof plug can stop flow from the end of 1/4 in tubing, and Rain Bird sells a 1/4 in tubing plug that serves as an end plug for flushing and draining. More in Drip tubing end caps, figure-8 closures and flush points

Identify both ODs first. Then use a reducing coupling made for that exact pair, such as DIG's D50G (.700 to .620 in OD) or D50B (.700 to .710 in OD), or a coupling whose maker lists both sizes. More in Join .700 drip tubing to .620 or .710 tubing

Several makers list a range that includes both. Orbit lists its 67466 coupling for .620-.710 in OD, and Raindrip lists its Smart Loc S5600UB for .520 x .620, .600 x .700 and .620 x .710 in tubing. More in Join .700 drip tubing to .620 or .710 tubing

It depends on the ODs, not the brands. Rain Bird T70 and DIG's 1/2 in tubing are both listed at .700 in OD, while Rain Bird T63 and T71 are 0.63 and 0.71 in OD. More in Join .700 drip tubing to .620 or .710 tubing

Rain Bird lists Easy-Fit for 0.63-0.70 in OD tubing, so the .710 end is outside the stated range. More in Join .700 drip tubing to .620 or .710 tubing

UMaine Extension advises sealing it with the small end of a goof plug, using the larger end if the hole is ripped, and cutting out the section and installing a coupling if it still leaks. More in Repair split or punctured drip tubing: plug, splice or replace

We found no maker that says so; goof plugs are described for holes and ends. For a split, DIG says to cut out the damaged section plus about an inch each side and splice in new tubing. More in Repair split or punctured drip tubing: plug, splice or replace

Raindrip's FAQ says squirrels and other rodents chew its products to get water, and suggests setting out water containers or covering the product with wire mesh. More in Repair split or punctured drip tubing: plug, splice or replace

One whose maker lists your tubing's OD, or both ODs if the new piece differs. Orbit lists its 67466 for .620-.710 in OD; Raindrip lists Smart Loc S5600UB for .520 x .620, .600 x .700 and .620 x .710 in. More in Repair split or punctured drip tubing: plug, splice or replace

Rain Bird warns that a single night below 32°F can split thin-walled drip tubing, because water expands when it freezes. More in Repair split or punctured drip tubing: plug, splice or replace

No. Each maker lists a size range: DIG NUTLOC .630-.710 in OD, Orbit 67466 .620-.710 in OD, Rain Bird Easy-Fit 0.63-0.70 in OD, and Raindrip Smart Loc three ID x OD pairs. Tubing outside the range is outside the listing. More in "Universal" drip fittings: the OD range behind NUTLOC, Smart Loc and Orbit

By OD, Rain Bird's T63, T70 and T71 tubing (0.63, 0.70 and 0.71 in) all fall within the .620-.710 in OD range Orbit lists for its 67466 coupling and 67468 end cap. More in "Universal" drip fittings: the OD range behind NUTLOC, Smart Loc and Orbit

No. Orbit's 67466 Universal coupling locks with a hand-twisted nut and is listed for .620-.710 in OD; its 67491 Drip-Lock coupling is push-on with a release tab and is listed for .690, .700 and .710 in OD. More in "Universal" drip fittings: the OD range behind NUTLOC, Smart Loc and Orbit

It differs by maker: DIG lists NUTLOC up to 60 PSI, Rain Bird lists Easy-Fit at 0 to 60 psi, and Raindrip says Smart Loc S5600UB handles up to 50 psi. We found no pressure rating on Orbit's 67466 page. More in "Universal" drip fittings: the OD range behind NUTLOC, Smart Loc and Orbit

Of these, Orbit 67466 (.620-.710 in OD) and Raindrip S5600UB (.620 x .710 in among its sizes). Rain Bird Easy-Fit is listed for 0.63-0.70 in OD only. More in 1/2 in drip fittings with a stated OD range

No. Rain Bird says Easy-Fit adapters are not barbed fittings and are to be used only with Easy-Fit compression fittings. More in Drip connection type finder

With an adapter made for the pair, such as DIG's 50007 swivel adapter (3/4 in FHT x 3/4 in MNPT) or its D49 nipple (MHT x MPT). More in Drip connection type finder

Raindrip says mismatched or cross-threaded connections are the main cause of leaks; match hose thread to hose thread and pipe thread to pipe thread. More in Drip connection type finder

It depends on the maker. DIG lists .600 x .700 in (ID x OD), Raindrip's 062010P is .620 x .710 in, and Rain Bird sells T63, T70 and T71 at 0.63, 0.70 and 0.71 in OD. Measure or read the OD of yours before buying fittings. More in 1/2 in and 3/4 in drip tubing, by outside diameter

Compare the OD, not the brand. Rain Bird's T70 is listed at 0.70 in OD and DIG's 1/2 in tubing at .700 in OD, so those two match by size. Rain Bird's T63 and T71 are different ODs, and Rain Bird gives no ID. More in 1/2 in and 3/4 in drip tubing, by outside diameter

Raindrip says its supply tubing and feeder lines can be buried, but its drip tubing should not be, because buried emitters risk clogging. Follow the maker of the tubing you have. More in 1/2 in and 3/4 in drip tubing, by outside diameter

Makers build it in. DIG says it adds at least 2% carbon black to its polyethylene tubing for UV protection; that is a formulation statement, not a promised service life. More in 1/2 in and 3/4 in drip tubing, by outside diameter

DIG lists its 3/4 in tubing (14-000 and 14-002) at .820 in ID x .940 in OD, rated up to 60 psi. Its page also mentions a .920 OD, but only the .940 OD tubing is in the ordering table. More in 1/2 in and 3/4 in drip tubing, by outside diameter

There is no single size. Makers list 1/2 in tubing at about .620-.630, .700 and .710 in outside diameter; Rain Bird alone sells T63, T70 and T71 at 0.63, 0.70 and 0.71 in OD. More in What size is your 1/2 in drip tubing? .620, .700 and .710 OD

Neither exactly. "1/2 in" is a name, not a dimension. DIG's 1/2 in tubing is .600 in ID by .700 in OD, and Raindrip's 062010P is .620 in ID by .710 in OD. More in What size is your 1/2 in drip tubing? .620, .700 and .710 OD

Its FAQ lists backflow device, timer, pressure regulator, 150-mesh filter, then the poly faucet fitting, and warns that a regulator before the timer can build up excessive pressure. That order is for its system only. More in Mister Landscaper drip and micro-spray system

It requires the 25 psi MLD-25PR for drippers only or drippers mixed with micro sprays, and suggests the 50 psi MLA-58 for micro sprays. More in Mister Landscaper drip and micro-spray system

Mister Landscaper links a brass vacuum breaker on Amazon as a replacement. Whether a device meets local requirements is for your water utility; see backflow preventers. More in Mister Landscaper drip and micro-spray system

Yes. Netafim says the check valve keeps water from draining out of the dripline after zone shut-down. It gives no hold-back height. More in Netafim Techline CV dripline

None on the product page. It links a 17 mm fittings section and a dealer locator. A fitting whose maker states an OD range that includes 0.66 in is the fit evidence to look for. More in Netafim Techline CV dripline

Netafim lists pressure compensation from 14.5 to 58 psi, a 14 psi minimum and a 58 psi maximum system pressure, with at least 120 mesh filtration. More in Netafim Techline CV dripline

The tubing's outside diameter. DIG matches each insert color to an OD, and Rain Bird lists Easy-Fit by OD range (0.63-0.70 in). More in Compression fittings

Green is for .620-.630 in OD, black for .700 in OD and blue for .710 in OD. These colors are DIG's only. More in Compression fittings

DIG rates its compression fittings up to 60 PSI and recommends 15-35 PSI; Rain Bird lists Easy-Fit at 0-60 psi. See fitting types compared. More in Compression fittings

It is the maker's family name for 1/2 in class insert fittings. Rain Bird calls its XF insert fittings 17 mm barb-style; DIG labels its 1/2 in barbed range 16 and 17 mm without a barb diameter. More in Barbed insert fittings (1/2 in, 16 and 17 mm)

Rain Bird names its XF Dripline insert fittings, rated 0-50 psi, or Easy-Fit compression fittings. More in Barbed insert fittings (1/2 in, 16 and 17 mm)

The distributor listing we read does not call it Perma-Loc. It lists .590-.630 in ID in inch values. See joining metric tubing. More in Barbed insert fittings (1/2 in, 16 and 17 mm)

The barb sits inside the tubing and the nut closes over the outside. DIG lists NUTLOC by ID (.530, .600, .620 in) and OD (.630-.710 in), and Raindrip lists ID x OD pairs. More in Locking-nut and spin-lock fittings

Orbit calls it reusable: loosen the nut to remove the tubing. More in Locking-nut and spin-lock fittings

Drip Depot says not to remove the swivel collar: twist it back, push the tubing over the barb until covered (about 0.5 in), then tighten it. See tubing popping off or leaking. More in Locking-nut and spin-lock fittings

No source maps punch sizes to barbs. DIG sells 2, 3 and 4 mm punches, and UMaine says to use a punch made for drip tubing and matched to the barb. More in 1/4 in barbed connectors

Drip Depot lists tubing on the dripper outlet instead of the inlet, pressure too high, ends not cut straight, and vinyl tubing in high heat. See tubing popping off or leaking. More in 1/4 in barbed connectors

Rain Bird's SPB-025 self-piercing barb joins 1/4 in tubing to 1/2 or 3/4 in tubing, inserted with the XM-Tool. More in 1/4 in barbed connectors

FHT is female (inside) hose thread and MHT is male (outside) hose thread. DIG's D45 backflow preventer, for example, has a 3/4 in FHT inlet and a 3/4 in MHT outlet. More in Hose thread (FHT and MHT)

Raindrip says to match hose thread to hose thread and pipe thread to pipe thread. DIG lists adapters between them: D49 (MHT x MPT) and 50007 (FHT x MNPT). More in Hose thread (FHT and MHT)

ASME B1.20.7 covers screw threads for hose couplings in sizes from 1/2 to 4 in. Its page does not use the name 'garden hose thread'. More in Hose thread (FHT and MHT)

Makers use both for female pipe thread: DIG writes FNPT on its 24-029 adapter, and Rain Bird writes FPT on its Xeri-Bug XBT inlets. More in Pipe thread (FPT, MPT, NPT)

ASME B1.20.1 covers general-purpose inch pipe threads, including tapered NPT. Hose threads are covered separately by ASME B1.20.7. More in Pipe thread (FPT, MPT, NPT)

DIG lists the 50007 swivel adapter (3/4 in FHT x 3/4 in MNPT) and the D49 nipple (MHT x MPT). See drip faucet head assembly. More in Pipe thread (FPT, MPT, NPT)

A small screw thread some devices use instead of a barb. Rain Bird sells Xeri-Bug emitters with a 10-32 inlet and the PFR-12 riser for 10-32 threaded devices. More in 10-32 thread on emission devices

Only the -1B assemblies (300-1B, 308-1B, 309-1B), which include a 13 in stake, 12 in riser and 1/4 in barb. The 300B, 308B and 309B are bare 10/32 heads. More in 10-32 thread on emission devices

CSU Extension advises a separate zone for micro-sprays because they use much more water, and Raindrip says never to mix drippers and sprinklers on the same line. More in 10-32 thread on emission devices
