I was taking a shower tonight and had low pressure, figured the wife had started the washing machine. Nope! So I go out to the well and the gauge is on "0" and no humming . I pulled the cover on the pressure switch and the contacts are made. I checked the breaker and alls well. I'm gonna wait until morning and check the contacts and clean them and assure that voltage is there. Is there anything else I can do? I'm thinking after that point its time for the professionals. It is a submersible appx. 150' deep.
