Heck, I am not an expert on water systems so can add little to the problem other than what I have been told. In the course of the discussions it was mentioned that when the water meter was replaced something was also done with the "Check Valve" and the home owner was to be told of the meter change/check valve adjustment or something to that effect. We were not told. I was also told the "push pull" valves are the cheapest and should be replaced when appropriate. We have a plumber coming this morning who is going to replace the bathroom push pull valves and also look at the extension to see if it is OK or replace it? The PSI for our area was checked and it is at 58psi and I understand it should be between 50 and 60 so it is fine. No one can tell us with any absolute definition why ours blew out and with the force it used.
