The H2OWize Spray to Drip Converter (Retro-Drip Kit) is a simple, highly effective solution designed to transform any existing pop-up spray head into a water-saving, low-flow drip irrigation zone in minutes. Instead of tearing up your yard to trench new pipes, simply unscrew your old, inefficient sprinkler head and thread this low-profile retrofit kit directly onto the existing underground riser. It seamlessly connects to standard 1/2" mainline tubing or emitter tubing to deliver precise, targeted watering exactly where your newly planted shrubs, flower beds, or vegetables need it.
Engineered for universal compatibility, this all-in-one converter works flawlessly with underground spray bodies from all major irrigation manufacturers. Inside the compact housing, it features a built-in 30 PSI pressure regulator and a 150-mesh screen filter to protect your delicate drip emitters from clogs. Capable of handling high inlet pressures from 15 to 80 PSI and supporting flow rates between 0.5 and 6 Gallons Per Minute (GPM), the kit includes two 1/2" barbed fittings and one 1/2" cap. This clever design allows you to run 1/2" drip line in two different directions, or cap one side off for a single, straight run.

Convert your old spray head to a drip zone safely and effectively.
Step 1: Remove Old Sprinkler
Ensure the water to the sprinkler zone is completely turned off. Dig slightly around the base of the existing pop-up spray head and unscrew it counter-clockwise from the underground threaded riser.
Step 2: Attach the Converter
Thread the inlet of the H2OWize Converter directly onto the exposed 1/2" riser. Hand-tighten until secure, ensuring the housing sits near grade level.
Step 3: Connect Tubing
Push your 1/2" mainline tubing or emitter tubing firmly onto one or both of the included barbed fittings. If you are only running tubing in a single direction, use the included cap to seal off the unused side.
Step 4: Routine Maintenance
Periodically (once a season) unscrew the top cap of the converter housing, remove the 150-mesh filter screen, and rinse it under clean water to remove any trapped sediment.
Will this work with my brand of sprinklers?
Yes, the H2OWize Converter is universally compatible. It is designed to thread onto any standard 1/2" Male Pipe Thread (MPT) riser, which is the standard size used by almost all major manufacturers (Rain Bird, Hunter, Toro, Orbit, etc.).
Simply unscrew the old head and thread this directly on in its place.
Can I run tubing in two different directions from this kit?
Yes! The kit intentionally includes two 1/2" barbed fittings, allowing you to attach tubing to both sides of the converter to water beds on either side of the sprinkler riser.
If you only need to run tubing in one direction, simply use the included cap to seal off the second port.
Do I need to buy a separate pressure regulator or filter?
No, this is an all-in-one unit. The H2OWize Converter has a 30 PSI pressure regulator and a 150-mesh screen filter built directly into the housing.
This ensures your new drip line operates safely without blowing out or clogging, eliminating the need to purchase any additional head assembly parts.
How should I prepare my H2OWize Converter for spring watering?
Prepare the unit for spring by unscrewing the top cap and inspecting the 150-mesh screen. Clean out any sediment or scale that may have accumulated over the winter.
Ensure the O-ring is properly seated before hand-tightening the cap back on. Turn the system on to verify water is successfully flowing down your 1/2" drip tubing.
