Water pressure booster pump won't turn on
I have an AquaPro JETm-40w with a Square D 9013 FSG-2 pressure switch. It regulates pressure from a 2500 gallon tank on a tower. There's an automatic shut off that floats in the tank and prevents the pump from running if the tank is empty.
We've had no problems until 2 days ago, when it stopped turning on. The pressure gauge is at 10 lbs and doesn't fluctuate (it used to sit at around 30lbs). What should I do to troubleshoot?
I have ensured the water tank was full. That's about it. There appears to be some damage (dog chew marks) in the flexible piping that covers the wires from the automatic shut off float. The damage doesn't seem to be deep enough to get through to the wires though, so I think the problem must lie elsewhere.
