HOW TO SHUT-OFF THE WATER TO
YOUR SPRINKLER SYSTEM

To turn the system off at the water source, you will need to locate the SPRINKLER CUT OFF VALVE or backflow device for the sprinkler system. This will turn off the sprinkler system water without turning off the water to the whole house.

The backflow device is usually located near the street in a rectangular box with a green lid. In most cases the box sits inside the property line near the water meter. It may be difficult to see, since grass may have grown over the cover! The device should be accessible and it should look like the picture to the left.

Once you have located the device, turning it off is the next step. The handles of these devices are notorious for twisting off due to corrosion. Be careful when forcing these handles, they can cause a nasty cut if broken off. You may want to wear some leather gloves. Each backflow device has two cut off valves, each does the same job. They turn off the water at the source without turning off the water to the sprinkler system. Turn either handle "OFF" as shown below.
