Hello all, I have two set of irrigation valves, one set for the front yard and the second set for the back yard. While the second set turning off one after another after watering, a loud bang could be heard under the house where the water supply runs on copper. But I have no trouble at all with the front yard valves where located in the front yard and the second set located in the back yard. The only difference I can see from observing them is that the back yard valves are not raised high enough (6") wihen compared to the front yard valves. Can this be the problem? The irrigation system is layout with PVC pipes (1") and just had them for months. Please advise.
