How to Install a Microsprayer Sprinkler Head System

Like drip irrigation, a microsprayer system can be quite useful in a waterwise garden. The nozzle spray patterns and watering amounts can be adjusted according to plant requirements, unlike with a conventional irrigation system.

Highlights:

Step 1: Unwind the Polyethylene Tubing

Allow the polyethylene tubing to sit in the sun for an hour or more. The heat will make it more malleable and easier to work with.

Step 2: Connect the Hose Adapter and Pressure Reducer

Clamp a hose adapter to the end of the 1/2" polyethylene tubing. Attach a pressure reducer to the hose adapter at the end of the tubing by screwing the two ends together (Image 1). To help prevent leaks, apply Teflon tape to the threads of the reducer. Slide a small clamp onto the 1/2" tubing. Insert the tubing into the other end of the reducer. Slide the clamp up to the reducer and crimp (Image 2).

Step 3: Install the Microsprayer Nozzles

Mark the location for the first nozzle on the 1/2" tubing. Poke a hole through the pipe using a landscaping staple (Image 1). Push the microsprayer nub into the hole and listen for a snap (Image 2). This indicates that there is a good connection. Finish installing the other microsprayer nozzles about five to six feet apart for ideal coverage. Secure the tubing to the ground with landscaping staples.

Step 4: Flush the System

Prior to running the system, remove the nozzles and allow the water to flush any debris out of the pipe. Reinsert the nozzles and place at least six inches above the soil surface.

Step 5: Hide the Tubing

Cover the 1/2" polyethylene tubing with mulch or topsoil so that the nozzles are the only visible indicator of the microsprayer system.
