Dripper Line 3mm (Internal Diameter) - 20 Metre Roll - Feed Tubing for DIY Drip Irrigation
Best for: growers building or repairing a DIY drip irrigation setup who need feed tubing sized for standard 3/4mm dripper fittings.
Our thoughts
This is a simple, functional roll of feed line rather than anything flashy, and that's exactly what it needs to be. If you've got a dripper stake, T-piece or fitting that's rated for 3/4mm line and your existing tubing has split or perished, this is the straightforward replacement. Good value for a full 20 metre roll rather than buying it in short pre-cut lengths.
This is a 3mm internal diameter dripper line supplied by IWS, a UK hydroponic irrigation brand, on a full 20 metre roll. It's the small-bore feed tubing used in drip irrigation systems to carry water and nutrient solution from a main supply line out to individual dripper stakes or emitters at each plant.
It's designed to work with standard 3/4mm fittings, the small barbed connectors, T-pieces and dripper stakes commonly used across DIY hydroponic irrigation kits, which makes it a practical choice both for building a new system from scratch and for replacing worn or split dripper line on an existing setup.
How it compares
Small-bore dripper line is a fairly standardised product, so the main differences between brands come down to durability and availability of matching fittings.
- AutoPot systems use similar small-bore feed tubing throughout their range, and this line is compatible with 3/4mm AutoPot-style fittings.
- Netafim, one of the pioneers of modern drip irrigation, produces small-bore dripper line for commercial and hobby use at a similar scale.
- Hozelock's micro irrigation range covers comparable tubing sizes aimed more at general garden watering kits.
Because the fitting standard (3/4mm) is common across most DIY hydro irrigation kits, this roll is a safe, compatible choice regardless of which brand of drippers or stakes you're already running.
Usage guidance
Keep runs as short and direct as practical for even flow across all your drippers.
Connecting to fittings
Push the tubing firmly onto barbed 3/4mm fittings, T-pieces or dripper stakes until it seats fully, to avoid leaks or the line popping off under pressure.
Cutting to length
Cut cleanly with a sharp blade rather than scissors, which can pinch and distort the bore, affecting flow at that dripper.
Replacing old line
If your existing dripper line has gone brittle or split, particularly where it's been exposed to light and heat, this roll is a straightforward like-for-like replacement.
Layout
Plan your runs so each dripper gets a broadly similar length of feed line where possible, as long, uneven runs can lead to uneven flow rates across a system.

Our take
There's nothing complicated about dripper line, it either fits your system and holds up, or it doesn't, and this does the job at a sensible length and price. A 20 metre roll covers a decent number of plants or gives you plenty of spare for repairs.
Does exactly what it should, day in, day out. Worth keeping a spare roll on hand for repairs.
