Turn on the irrigation to check for leaks before burying the pipe and fitting.The pipe can be abandoned, as it is no longer connected to the irrigation system. Dig up the dirt around the sprinkler you want to remove and unscrew it from the fitting beneath it.

Cut the pipe just past the tee fitting leaving enough pipe sticking out of the tee to cap it.Dig up the pipe and fitting under the upstream head.During winterization, the water would be trapped in the "dead end" and may potentially freeze and break the pipe. Capping the pipe at the upstream sprinkler prevents a "dead end" of pipe that would fill with water but not have any outlet. If the sprinkler you want to remove is the last one on the pipe, you will need to locate the sprinkler that is "upstream" (closer to the source of water from the sprinkler you want to remove) and cut and cap the pipe there. Use these instructions if you live in an area that does require winterization:

Turn on the irrigation to check for leaks before burying the pipe and fitting.

Install a cap or plug of the appropriate size or thread to stop the water from flowing out of the fitting after the sprinkler is removed.

Unscrew the sprinkler and any piping connecting the sprinkler to the fitting below.

To cap off a sprinkler, dig up the dirt around the head you want to remove so you expose the pipe and fittings below.

Use these instructions if you live in an area that does not require winterization: Winterizing your irrigation system involves draining or blowing the water out of the system with compressed air to prevent freeze damage. If you cannot locate your valve boxes or fix the valve, it is recommended you contact the contractor who installed the system or use our Professional Contractor Referral link to help find a contractor in your area.Ĭapping or removing a sprinkler is done differently depending on whether or not you live in an area that freezes and requires the irrigation system to be winterized.

To fix this, you'll need to disassemble the valve, rinse all the parts with clean water, and re-assemble the valve. Typically, water will leak through a valve because debris is in the valve. Note: A check valve in the sprinkler will not fix this leak. Another reason may be water leaking through the valve.To fix low head drainage, install check valves on the sprinklers or in areas with extreme elevation change, you may need an HCV underneath the sprinklers exhibiting this issue. Eventually, the water leak will stop after all the water has leaked out of the pipe. The most common reason is called "Low Head Drainage." This is when the lowest head on the zone leaks the water from the piping out the sprinkler.There are two reasons why there might be a wet spot around your sprinkler: Why is there a wet area around my sprinkler or rotor? Greenhouse, Nursery, and Open-Field Irrigation.
