I had the termite guys out to treat for termites and while they were filling their 65 gallon water tank my pump quit pumping. I looked at the presure switch and the contacts looked quite worn and dark. I replaced it but still nothing. I can hear the control box clicking on and off. That is all I can hear.Is this faulty control box or do you think the pump bit it.I will say that this pump has not been used on a regular bases since 2002. It has been off most the time and only turned on occasionally approxomatly a total of 60 days since.
