I just bought a house in the country, it has a deep well and a shallow well. Last night the pressure gauge dropped to zero and I had no water. The blue tank in the basement is empty, I flipped the switchs by the tank and got almost imediate water pressure(45) and had water for a little while, then it went to zero. It did this a couple of times while I played with it, but it wont hold pressure. I cant seem to get wateer from the deep well to the house, although I get water from the spicket at the well..
