I have a 1999 Catalina 320. The shower works well but the shower bilge pump does not turn on. On the main panel is the toggle for the shower bilge pump and its turned on. There is a switch right above the toilet but doesnt do a thing ! Any suggestions????

Does the bilge pump work if you place a direct 12VDC across its red and black leads?. and what happens if you by pass the float switch. There should be 12VDC across the switch when off. If not then you are getting power from the panel to the switch in the bath room. This is an easy fix.

Sounds like a bad pump.

On my C-320 it's accessed by unscrewing and removing the toilet-paper holder. Make sure the DC panel switch for Water Pressure/Shower Sump Pump is ON; then use the waterproof switch in the head to activate the sump pump. Run it until the sump sounds dry...there is no float switch.

BTW, make sure the through-hull is open.

If the pump cannot work, I'd sponge out the sump rather than let soapy water fester. Access the sump by unscrewing and removing the floorboard at the front of the head door. Next to the non-fastened smaller bilge pump floorboard.
