Water pressure tankReport
Please briefly explain why you feel this question should be reported.
I watched your video on pressure tanks. I have no water at the moment. The gauge is reading zero. I checked the pressure in the tank like you showed and it was down to 20PSI. I added air pressure, but the gauge is still at zero.
How do I know if the switch is bad, or maybe the bladder inside the tank, or what else could be going on?
