WINTERIZE YOUR IRRIGATION RISER Help keep maintenance costs down by winterizing your irrigation service riser and valve. If done properly, next Spring you will not have a leaky or a broken valve.
- This should be done after water delivery has ended for the season.
- Drain your riser and valve. Disconnect your hoses and/or irrigation system from your riser and open your valve. If your irrigation system cannot be disconnected, open all sprinkler valves and let them drain. Drain times will vary from place to place so be patient and wait for the water to stop flowing out of the riser.
- Once the water flow has stopped you can winterize your system. Consult with a professional to determine the proper winterization procedure for your system. Personal injury and/or property loss can occur if winterization is not done properly or completely.
- After your system has been drained, fully open and close your valve several times to ensure that water is not trapped inside the valve or riser.
- Repeat the process several times, until both your sprinkler system and your service riser are completely free of water.
- Close your service valve and leave it closed. If your system was disconnected from the riser, do not reconnect it until next spring.
