About Watchmarks Irrigation
Watchmarks Irrigation helps readers with one job: home gardeners watering raised beds, vegetable rows and containers from an outdoor faucet, homeowners adding drip to shrubs, trees and foundation plantings, or converting a sprinkler zone to drip, owners of an existing kit (Rain Bird, Raindrip, DIG, Orbit, Mister Landscaper and similar) adding or repairing tubing and fittings from another brand, balcony, patio and greenhouse growers running 1/4 in microtubing to pots and hanging baskets and buyers of low-cost AliExpress kits whose metric 4/7 mm and 16 mm tubing has to join US 1/4 in and 1/2 in parts.

What we cover
- Mainline tubing (1/2 in and 3/4 in polyethylene, by outside diameter)
- Microtubing (1/4 in and metric 4/7 mm distribution tubing)
- Drip line (inline-emitter and soaker-style drip tubing)
- Drip emitters (fixed and adjustable, by GPH, pressure-compensating or not)
- Micro-sprays and bubblers (with stakes and risers)
- Mainline fittings (compression, barbed insert and spin-lock tees, elbows, couplings and end closures)
- Microtubing connectors (1/4 in barbed connectors, hole punches and goof plugs)
- Head assembly parts (backflow preventers, filters, pressure regulators and faucet adapters)
What we do not cover
- Fertilizer injectors, fertigation, liquid fertilizers, pesticides, herbicides, chlorine or acid line cleaners and other chemicals
- Claims that a backflow preventer or anti-siphon valve meets a local plumbing or health code, or that a system is safe to connect to drinking water (the site points to the local water authority and the maker's documentation)
- Drinking-water, lead-free or food-safety claims for tubing and fittings beyond the maker's own stated certifications
- Instructions for wiring controllers, valves, pumps or transformers to mains power, and work on household main water lines or meter connections
- Water-saving, yield or plant-health guarantees, and water-use or flow figures beyond what the maker publishes or presented as tested by us
- 'Universal' or 'fits all' claims without the actual tubing diameters or thread types stated
- Gas-powered or electric pumps, rainwater-tank systems and greywater systems (outside this segment)
- Smart controllers, Wi-Fi hubs and in-ground sprinkler valves as recommendations (they appear only as the reference systems drip parts connect to)
