In response to Re: water hammer
Do you have a long supply line from the meter to the house? Is the sprinkler system connected before or after the PRV? Put the gauge on the hose faucet and then operate the sprinkler system. Watch carefully. You may see the pressure drop to zero for an instant and then go off the gauge when the water hammer occurs.

: When my automatic sprinkler valves come on I get water hammer in the pipes of the house. I know this is common when water shuts off but in my case it happens when each of the valves open. I have a pressure regulator on the main house supply that is set to 60 psi and I installed a water hammer arrester in the supply line close to the sprinkler valves and it has not helped. Any ideas?
