Do all sprinkler systems have a master valve?

Master valves are a common component in most irrigation systems, but they are not always required. A master valve is an automatic valve that is installed at the point where the irrigation system connects to the water supply.

Will sprinkler heads freeze?

Water can also freeze inside sprinkler heads themselves. As the frozen water expands, the pressure from the ice can pop off sprinkler heads.

How long does it take pipes to freeze at 32 degrees?

Pipes can freeze in as little as six to eight hours, meaning they can freeze overnight. If the outside temperature is below 32 degrees F and your pipes are unprotected, your chances for a frozen pipe increase.




Is there a main shut-off valve for sprinkler system?

Locate the main shutoff valve on your irrigation system. It is between the main water supply to your home and the sprinkler controller. Alternately, the main shutoff is located outdoors near a faucet bib. The main valve may be in a box in this area to protect it from the elements.

How do you winterize a sprinkler system with a backflow preventer?

Turn off water to the backflow preventer. Most have an isolation shutoff valve located below ground before the backflow preventer. Open test cocks on the backflow preventer to drain all the water from it. Once water is drained, close both shutoff valves with a one-quarter counterclockwise turn.

Should you leave sprinkler valves open in winter?

Manual valves should be left in the open position throughout winter to prevent re-pressurization. Some sprinkler heads have both side and bottom pipe inlets. If you use the side inlet, install a drain valve on the bottom inlet to prevent the case from freezing.
