Well tank regulator rapidly lossing pressure
When I turn on any water out let, pressure drops from it's usual 60psi to under 10psi then goes on a irregular jumping from 10 to 50 and between for a while then stays under 10 until I turn the water off from the tank to the house. It then rises back to the 60psi until I open the value then it drops rapidly and you hear the pump turn on and off quickly and then stays at 10psi until I turn the value off from the tank to the house... Does anyone have an idea what could be the issues here? Thank you in advance!!
At the mercy of my Tank!
