Weirdest thing, I have 2 pumps connected to my pump controller. The controller is in the dry electrical compartment of my sump. I keep on seeing salt creep on both pump connectors to the controller. There is no water whatsoever anywhere in this compartment. No salt creep anywhere else, just on the pumps connectors. The pumps cables are bone dry as well as everything else in this compartment. I keep on cleaning these connectors but in a week time there is salt deposit again. Saltwater must be getting to the connectors but I can't figure out from where. Could it be possible for saltwater to get inside the pump wire?
