We are suddenly w/o water after having all day today. We are wondering if this is an issue with the fuse being blown. I am not a plumber, so this question may sound silly, but where is the fuse found on a submersible well pump? We are hoping this is not a major problem as we had a new well with this pump installed about 6-7 yrs ago.

Your pump is most likely on a circuit breaker. That would be the big gray box in the nearest enclosure. If any of them shows red reset it. Good luck, Tom
