We have city water, which goes into junction box which includes well water. We usually just use city, but last month it was $80 bill!! I think we may have a bad check valve in well as we possible left the tee valve allowing city water to go to well.. Is this possible? Either this or a leak in ground. #2 problem: Pump cycles to 60 psi, bleeds down to 40 psi and kicks on again, then pumps up etc...this is with NO water being used at the house and everything turned off. Could a check valve in pump be the cause for BOTH problems...
~City water into well
~Frequent cycling of pump with no water being used and water to house turned off...please help!
