I had a gfi trip in a bathroom that would not reset. Since I had a spare gfi, I installed it and the new one would not reset. A corresponding event was a water hose was left on for 30 minutes flooding the area where the underground wire runs from the street to the meter. I waited 24 hours for the ground to dry up a little then tried the gfi and it reset. Do you think my analysis was correct that the flooding caused the gfi reset (2 others did not trip but are located further from underground wire)? Do you think that there is a problem with the 30 year old wire conduit that runs to the house?
