Time to Winterize Your Sprinkler System

Summermay not end officially until September 21, but it’s not too early to start planning for winter. And it’s easier to maintain and repair your sprinkler system while the weather is still warm, rather than waiting until the snow flies.

Why should you worry about winterizing your sprinkler system?

If you don’t shut off your stop and waste and drain the system, water stays in the pipes over the winter. If the winter is mild – and you’re lucky – that might not do any harm. But chances are the cold winter weather will freeze the water left in the pipes and cause at least one pipe or joint to burst. Then when we pressure up the pressure irrigation system (PI) in the spring (or when you turn on your culinary-connected sprinkler system), water will spew out of the burst pipe and cause a flood in your yard, your house, or possibly the neighbor’s house.

As you can see from the chart at the bottom of this page, it’s time to start tapering off on watering your landscape anyway. Due to the water rights we hold, our PI water will be cut off on October 15, so no PI water will be available after that date.

If you don’t know how to shut off your stop and waste and drain your sprinkler system, please consult a qualified landscaper. WaterPro is not responsible for your system past the stop and waste or the meter, and we are unable to help individual customers winterize their systems.
