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?
