Have a well 490 ft deep . It is protected by a PumpTec system. Water ran for about 3 minutes and then stopped. PSI down to 10. The pressure switch is making contact.
When switch is manually opened and allowed to close, PumpTec makes a growling hum for about 4 seconds and then stops.
Have shut off water a house to see if I have a leak I don't see. Did not hear water pumping up from well.
Any suggestions greatly appreciated.
Chuck
