Sprinkler Backflow Preventer Leaking – How do you fix?

Step 1 – Turn Off The Water Supply

A broken backflow device can cause a lot of water damage to your home if no precautions are taken. To prevent this from happening, you must turn off the main water supply to your home before checking for any leaks in the system.

You can do this by turning off the main valve that feeds your sprinklers and then checking all other valves in the system to see if they are open or closed. The valves will be next to and behind the heads themselves.

Step 2 – Remove The Old Device

After shutting off water supply, you should remove the device from the sprinkler system. This is done by disconnecting the ends that connect to the main water supply and main line in your home.

Once you have these disconnected, they should be replaced with new ones when putting everything back together.

The old device may be corroded or damaged inside the connections. Try flushing it out with a hose. If this does not work, you will have to replace it.

Step 3 – Replace The Device

Before putting the device back on your sprinkler system, you should check for any leaks or corrosion. You can test leak pressure by turning the water supply back on and attaching the device to the main line first.

After checking for leaks, you should then attach it to your sprinkler system. First, you will need to put the rubber gasket in place and screw down the ends of the device until they are tight.

Step 4 – Turn The Water Supply On And Check For Leaks

Once everything has been tightened, turn on the water supply for a few minutes and check for any leaks. Be sure to check all these connections as well as the rings at the base, just in case.

If you have any leakages or corrosion after putting everything back together, you can try cleaning it with a garden hose first and then tightening everything down again if it is still leaking.

If this does not work, you will need to replace it.

Step 5 – Clean Out The Heads

If your sprinkler heads are spraying too strongly or weakly because of a leaky backflow device, you can check them by cleaning out the inside of the head with a screwdriver where the water comes out. This should be done after checking for leaks and tightening everything down again.

Once you have made these repairs and your sprinkler system is back in working order, you should then turn the water supply back on to make sure everything is running correctly.

You should expect to pay anywhere from $40 to $100 for this type of service depending on where you live and the time of year.

How often should a Sprinkler Backflow Preventer be replaced?

So make sure to check your sprinkler system for leaks or damage once every few years in case there are any problems that need to be repaired.
