A few years ago, I replaced the water pump for the freshwater system in my boat and added an adjustable well pump switch. Unfortunately used the Chinese equivalent of the Square D switch. The switch developed a leak and the pump was making noises. Replaced the switch with a Square D and cleaned up some rust on the contact terminals.

New switch started leaking water, #$%@! Removed that one, carried it back to the store and got it replaced. Reinstalled it yesterday. It commenced to leaking shortly after the installation, WTF!!! After an exhaustive analysis, the switch is leaking out of the switch electrical terminals, inches above the switch diaphragm, WTF!!!

With the system pressurized I found the leak. The shaft seal in the pump went bad. The motor partially filled with water. The pressure pushed the water through the multi strand wire, inside the wire covering, past the heat shrink sealed crimp connector, and on to the switch contacts.

You can't make this stuff up. Have no idea how the motor still ran filled with water.
