So I have been wanting a washdown pump on my boat and finally bought one, ended up getting a Jabsco. So after 2 days of a SUPER FUN install (because of doing 10 other wife projects while trying to do my own project) I finally got everything put back together. Now this is my first boat and first time installing a washdown pump, so this question is probably going to be stupid. But when I turned on power I heard NO humming sound from the pump to give me the warm fuzzy feeling that at least it works. I checked no fuses blown good solid ground,good connection to the switch panel but heard nothing. Is it even supposed to make any kind of sound, what am I missing?
