High water pressure help
I have lived in this house for 10 years. The toilet gizmo, in the tanks, do not seem to last very long before leaking and just running. I think I have high water pressure so I got a gauge that goes to 300 psi. Two of my hose bibs have pressure regulators on the end, the one that does not. Says my pressure is 125 psi. I had some one flush a toilet and the pressure went down to 50, until the toilet stopped filling up.
Can I really have pressure that high without the pipes breaking? What should I do? Might the gauge be broken? What made me start thinking my pressure was too high was when one of the toilets that has never been a problem started to just run and run but would stop if the water was turned on in a nearby sink or shower, but would start running again when the sink was turned off.
Any hints or ideas?
