How to Add a Rotor or Spray Head to an Existing Irrigation Zone

Sprays/Rotors - Parts and Components

Back Button

If you have increased the size of your garden, you can add new risers and heads to an irrigation zone as long as you have left room for growth. If the existing zones cannot handle more output, or the devices you want to add do not have the same flow rates as those already installed, you will need to add a new zone to the system.

Adding Irrigation / Sprinkler Risers


You can add new risers to an existing circuit (zone) in two ways: either along an existing line of PVC pipe or on a new line you branch off of from an old line. The steps below will show how to add risers to an existing line.

Blue Number 1

Cut Pipe

Locate the spot where you want to add a sprinkler head. Dig very carefully down to the pipe, making sure to not damage the pipe with the shovel. Excavate enough dirt that the pipe will be not be in danger of getting dirt or debris into it.. Using PVC ratcheting cutters or a saw, cut out a section of the PVC pipe wide enough to insert an adjustable slip-fix coupling and a tee fitting with a threaded outlet for the riser.


Blue Number 2

Install Fittings

Cement the slip-fix to one cut end of pipe and the tee to the other. Adjust the fittings to fit the space as necessary. Make sure to plan ahead so that the tee is facing straight up; remember that solvent cement dries very fast.



Blue Number 3

Attach the Riser

Using the appropriate height and type of riser for the location (here we use a Hunter Swing Joint Riser), wrap the riser threads with pipe-thread tape and screw the riser into the tee fitting.
