We are having trouble with our water well system. I don't know too much about water well systems so forgive me if I ask any stupid questions. What I do know is we have a 300 ft deep well, 1hp submersible pump, and the tank looks to be somewhere around 500 gallons (tank is close to 4 ft across 6.5ft tall) and the pump is down 120ft. There is a total of 8 houses on 30 acres currently tied into the well. The problem we are having is the well shutting off. The switch we have is a 40-60 psi switch(1yr old). We replaced the pump yesterday by hand (pain in the behind) and the pump has lost pressure twice today. I am thinking of calling someone out to check it out, but if anyone has any suggestions I would rather get hear them before doing so. do we need a bigger tank? My uncle thinks that if the tank was raised 10-15 feet it would help feed water more efficiently. Any suggestions?
