Short answer
DIG Microline is 1/4 in dripline at .170 x .250 in with emitters every 6, 9 or 12 in, rated 10-25 psi and 0.52 GPH per emitter at 15 psi. DIG's longest single run at 25 psi on level ground is only 16, 22 or 28 ft by spacing, though coils run far longer. The ML50 raised-bed kit adds a backflow preventer, a 25 psi regulator and 50 ft of .600 x .700 in tubing. See spacing and run length.

- Fitting type
- Not confirmedThe ML50 contents we read do not name fitting types.
- Threads
- Not confirmedThe ML50 contents list a 3/4 in backflow preventer but the thread types were not stated in what we read.
- Emitters or outlets
- 6, 9 or 12 in spacing; nominal 0.52 GPH at 15 psi (0.42 GPH at 10 psi, 0.65 GPH at 25 psi). ML50: 50 ft at 9 in spacing, 66 emitters, .52 GPH at 15 psi and .65 GPH at 25 psi[1][2]
- Filtration
- Minimum 150 mesh[1]
- Pressure regulation
- ML50 includes a 25 psi preset regulator[2]
- Maker cautions
- Longest single lateral at 25 psi on level ground: 16 ft at 6 in, 22 ft at 9 in and 28 ft at 12 in spacing, though coils run up to 3,000 ft. DIG's kit warranty says prolonged unattended use without inspection is beyond intended use[1][3][2]
- Parts the maker lists for it
- ML50: 3/4 in backflow preventer, 25 psi preset regulator, 50 ft of .600 x .700 in tubing and 50 ft of Microline[2]The backflow preventer is a kit part, not a code claim.
- Maker-page conflicts
- Not confirmedNo conflict recorded between DIG's Microline pages.
- Not confirmed
- Not confirmedDIG does not say whether Microline is pressure-compensating. No punch-to-connector pairing for the ML50 was confirmed.
Watch out for
- Coil length is not run length: DIG's longest single Microline lateral at 25 psi is 28 ft, at 12 in spacing.
- Microline's flow rises with pressure (0.42 GPH at 10 psi to 0.65 GPH at 25 psi), and DIG does not call it pressure-compensating.
- Spacing is a variant you choose: 6, 9 or 12 in. The ML50 kit uses 9 in.
- The ML50's backflow preventer is a kit part. What your faucet needs is for your water utility to decide.
