No, this didn't cause the leaks, you've had them for a while.The water pressure had lowered a couple of days ago, so as usual, I raised the pressure very slightly (as I have done on several occasions), but when I closed the valve when it reached 1.0, the pressure kept rising and stopped at 3.4. This caused a couple of leaks,
You need someone to solve the leaks, repair the filling loop, and I bet a service is long overdue too.Now we are trying to get everything put right.
