How to replace sprinkler valve diaphragm

The first thing you want to do is shut off the main water supply. Most sprinkler systems have a shut off valve. If you are connected to the city water main supply you should have a P.V.B valve or a ball valve and dual check valve.

The reason for the P.V.B or the dual check and ball valve is to prevent the sprinkler system water from going into the house drinking water.

If you look at the picture above you will see four Irritrol sprinkler valves. You will also see that the sprinkler valves are dug up properly. This is one of the most important steps.

You want to avoid getting any dirt or debris inside the sprinkler valve. This will help make sure that the sprinkler valve repair goes smoothly.

The second step is to remove all the screws. Be careful with this because there is a spring that’s inside the valve that you’re going to reuse.

Sometimes the tops of the valves can be hard to get off.

Take a screw driver and pry the sprinkler valve open gently. It’s very important you take your time.

The next step is extremely important. Once you have the top of the sprinkler valve you’re rebuilding removed flush the valve.

Next step you take your new sprinkler diaphragm and place it in the valve. In the example above we are replacing an irritrol one inch valve. With this certain valve you have to make sure all the holes line up perfect.

Once you have everything lined up perfect you simply put the valve back together exactly how you took it apart.

I Highly recommend when doing a sprinkler valve repair replace the top and the spring and diaphragm.

It’s not a must but since you already have the sprinkler valve apart you might as well replace everything.
