I had a blown bladder tank yesterday. Noticed short cycling of pump and tank was full of water. I replaced the tank today which went well all things considered (old house projects never go well!).
When I recharged the system, the pressure switch let the pressure build to over 80 before I cut it off at the breaker (it was previously set at 40/60 which would be fine for new tank precharged to 38). I have loosened the #1 screw about as far as it will go and the contacts still stay closed until 70/75. Measuring the pressure at the top valve of the tank confirms gauge is accurate (+/- 5 psi).
Where do I look now? Dismantle and clean everything? New pressure switch even though it was good when the project started? As I write this I am considering that maybe the switch went bad without me noticing which caused the high pressures I am currently seeing and caused the tank to fail....plausible? It's quite the journey to a hardware store so trying to solve this with 1 (or none?) additional trips.
Thanks!
