How do I determine the water pressure of my automatic sprinkler?

Answer by  phil9745 (160)

I believe there are 3 ways to do this, you can hook a pressure gauge to one of your outside faucets, hire a plumber that will already have a set-up to check water pressure, or quite possible contact your local water company and they will check it for you.

Go to the sprinkler head furthest from the supply and disconnect the sprinkler head and connect a water pressure gauge to the fitting. Activate the sprinkler system and the gauge will read the pressure.

To determine water presure you will need to install a "T" in the line with a quarter inch pipe thread opening. Also you will need to purchase a water presure guage and screw it into the tee. Turn it on and read the presure.

Most plumbing supply stores will sell a pressure gauge that you can hook up to an outside faucet. You attach it just like a garden hose and turn the water on. Once the valve is turned completly open; the dial will indicate the pressure that you currently have. This should give you the information you need.

The pressure of your sprinklers is determined by how many heads you have in the system. Another determining factor is how long of a run it is from the first head to the last head.
