Yesterday I lost pressure in my faucets. I recently disinfected my well. I believe, although not entirely sure, sediment shook loose and built up on the diaphragm of my old switch, and caused it to malfunction. It was around seven years old, and It was crusty when I took it off. I went and bought a new 30/50 pressure switch today, and replaced it, the nipple, and the psi reader. The new one also has a low pressure cut off switch. When I first installed it, it was operating at 28/48, I also checked the air in the pressure tank itself and it is at 28. Fast forward a few hours, and I’m running my tub and washer at the same time and all of a sudden my faucets go dry, the low pressure switch shut off the well pump(submersible), also seven years old. I flipped the switch and the water started right back up, now the switch is reading at 22-25 cut in and 40 cut off. The pressure tank is still reading at 28. Could anyone help me please with what could wrong? I don’t know if this means anything as well but the pipe has little shake to it when the cut off kicks.
