My first thought as well! Over the years I have had to replace my pressure switches far more often than any part of well systems. They are a very inexpensive item, available at Home Depot/Lowe's, etc. and are very easy to replace with simple tools (just make sure you kill the electric power first since you are dealing with 220+ volt wiring!)...
I can't even figure out which parts are which.
There's a tall tank-like thing with a dial near the top, there's a "water filtration" thing, there's a box with a sticker that warns of high voltage, and then there's a cylinder shaped plain thing going into the ground.
I'm guessing the latter is the pump?
I'll go back out and look for a pressure switch at the bottom of the tank but I think it was just a plain tank sitting on the ground.
My only neighbor that I know is "too friendly". I don't want him to know that my husband is away. I'd rather pay out the nose for a repair man.
