We recently bought a house with a water well on the property. We have city water service for the house, but would like to water the yard with the well water. We had a well service change out the downhole pump, pressure tank and all the associated plumbing. The well guy said that the well had plenty of water. The problem now is that when my wife waters, after the pressure switch kicks the pump back on, the pump is never able to replenish the water in the pressure tank. The pump continues to pump water at about 12 pounds on the pressure gauge for about 15 minutes, then the pump shuts off. I assume that the pump is shutting off to prevent overheating. Is the problem that the pump is too small, the pressure tank is too small, we’re expecting too much, or what?
