Recently, our pump 'tripped' and we called out a plumber to come to fix the problem. He tried a few things, including replacing the pressure tank and eventually the pump as well (the pressure switch too). Now he said that it's possible our well has gone dry. But we haven't seen signs of it going dry. It was a little cloudy, but it usually is after it rains. We've had no other problems with our water before this. And when I looked down in the well, it appeared to have water. One of our faucets -- the bathtub -- has a little water coming out of it now, but it's just a light drizzle. And that water is fairly clear. He said that the pump might not be powerful enough -- but I've also heard from someone we know who used to do plumbing work, that for our 30-foot well, that half a horsepower is enough and that the extra horsepower wouldn't work. (And it'd cost more on our electricity bills). I'm not sure if that's true or not, so I figured I'd ask here. Is it possible our well has gone dry, and we just didn't have any many symptoms? Would the extra horsepower be costly on the electric bill? We're only getting a little water from one faucet. I really don't know anything about wells, which is why I figured I'd ask here. Thanks for any advice you could give me.
