Anti-water hammer valves
I'm fighting a water hammer problem and was thinking about switching out my valves for something like the Rainbird PGA valves, that claim to be slow-closing to prevent water hammer. Anyone have any experience or recommendations for non-water hammer valves?
So far I've put a pressure reducing valve on my irrigation line, which is set at 35psi. Any lower and the sprinkler heads won't pop up. I also have a water hammer arrestor on the irrigation line, and another PRV on the house water line. I still hear a "thump" in the house whenever the valves close, so replacing them was my next thought. I'm hoping to get some feedback on whether or not these types of valves really prevent water hammer before undertaking the project.
