Winterizing Your Sprinkler System

Barring new information from the Utah Lake Board of Canals regarding water shut-off, WaterPro plans to drain the pressurized irrigation system on October 15th. To winterize your system, turn off your stop and waste, which is the valve that controls the water supply to your sprinklers. Even if your system has built-in drains, using an air compressor is recommended to blow the remaining water out of the pipes. Completely removing water will help prevent damage to pipes. Broken pipes can lead to flooding once water is put into the system next spring. If your system uses culinary water and includes a backflow assembly, it is critical to winterize the backflow assembly according to the manufacturer’s instructions. If you do not have the time, equipment, or expertise to drain and winterize your sprinkler system, call a qualified landscaper to help.

What is a Stop and Waste?

You might have heard about your pressurized irrigation system’s “stop and waste” valve and wondered how it got its name. This type of valve controls whether or not water is flowing to your sprinkler system. In the “stop” or off position, the valve is designed to drain water from the irrigation system. This process of draining water is called wasting; therefore, the name “stop-and-waste” valve. As pictured, the meter and stop and waste valve access indicate that your pressurized irrigation has been upgraded and may contain innovative technology (see article on page 2 of this newsletter, “Keeping an Eye on Your Water”). Your new stop and waste valve will be under a yellow or orange “snug cap.” To work this valve correctly, please scan the QR code or click the link below to watch the video “WaterPro: Your Irrigation Service and How to Operate Your Stop and Waste.”
