How to shut off the water to the sprinkler system

 

There are a few ways to shut down the sprinkler system.

o     At the controller

o     At the main valve

o     At the backflow preventer

 

At the controller….

Most controllers have an Off  button that is pretty clear to see. If that does not work most likely you have a stuck valve and need to try step 2.

            See stuck valve or look at the controller manual

 

At the main valve….

Usually in the basement this valve is found near the water meter. It most likely has a red tag on it indicating that it is the main valve for the sprinkler system. If you have a round handle valve turn it clockwise until it stops rotating. If  you have a lever type valve, known as a ball valve turn the handle so it is perpendicular to the pipe.

 

 

At the backflow preventer….

There are also two valves at the backflow preventer (PVB RPA) that can be shut off from outside. This is a good point to show your neighbor if you are not around for an extended period of time.
