We recently replaced the pressure switch and a relay on our well pump because it was running in short bursts every 5 minutes or so. Now it's running better but still about every 17 minutes, even with the water turned off to the house and barn.

We're going to have it pulled in two weeks and replace it, since it's a 37-year-old Berkeley; I'm not even sure there are parts for it! My question is, what's a good, reliable replacement unit?
