Last night i showered around 9pm. We are having a cold spell here in ny. It got to -6f this morning. A few hours ago i noticed my toilet was not refilling. Then i tried the faucet and nothing. Went down to the basement and the tank said 0psi. I checked the circuit breaker and it was all good. I have 220v going into and coming out of the pressure control switch. 220v are going into the capacitor box. I can feel and hear the hose from the well vibrating which I assume means the pump is running. There is just no water coming out. Im skeptical it has to do with the cold as the well pipe is around 4ft underground but in dont know much about plumbing. What could be causing my no water issue?
