Hello, we have been having water issues for the past month. We have a pressure gauge in our mechanical room that shows the pressure is normal but we will randomly loose water pressure so we have zero water in the house. We have had a well company come out 6 times now and they cannot figure out why it is happening. They thought it may be an electrical issue and have replaced all parts except the pipe in the well and the pump. Our well is 300ft deep and there is a lake about 200 meters across the street. When we lose pressure there is zero water in the house for about 30-45 mins then it's back to normal. Any ideas what could be causing this?
