Rainbird UNI Spray CAP

Rain Bird Uni-Spray Sprinkler Bypass Cap / Plug 🛠️💦

Tired of digging up your lawn just to decommission or block a single sprinkler head?

This custom-designed Bypass Cap is the ultimate time-saving solution for your Rain Bird Uni-Spray sprinkler system. Whether you are adjusting your lawn layout, fixing a zone, or simply want to shut off a specific sprinkler permanently or temporarily, this plug makes it effortless.

Why You'll Love It:

• No Digging Required: Save your lawn and your back! There's absolutely no need to dig up the entire sprinkler body from the ground.
• 10-Second Installation: Simply unscrew the top collar, pull out the internal pop-up riser assembly, and screw this cap directly onto the existing body thread.
• Clean & Low-Profile: Once installed, the cap sits flush with the top body, keeping your lawn looking clean and mower-safe.

TIP

For a 100% Leak-Free Seal: We highly recommend placing a standard 35mm diameter rubber gasket (or O-ring) inside the cap before screwing it down. This ensures a perfect water-tight seal and eliminates even the minor leaks under high system pressure.

How to Use:

1. Turn off the water system.
2. Unscrew the outer collar of your Rain Bird Uni-Spray sprinkler.
3. Remove the internal pop-up riser/spring assembly.
4. Insert a 35mm rubber gasket inside the 3D-printed cap.
5. Screw this custom cap tightly onto the sprinkler body.
6. Done! Simple, fast, and clean.
