[C320-list] Shower sump pump woes

[Bob Borelli]

The shower sump will not take suction for discharge with the sea valve closed.
Check that the sea valve is open.

I have removed, disassembled to clean and reinstalled the original pump & strainer.
Finally installed a new pump, strainer & hose to the sea valve.
Lube the sea valve with Forspare Marelube.

Access - remove the 2 drawers & than 5 wood screws in the frame & ease the cabinet frame assembly out & set it aside.
Now room to work.  You can remove the vanity to place a drop light in the opening to help see whats going on.

I replaced the original pump with the same so the 3 wood screws holding the base down would line up.
I purchased the new pump on Amazon.  I've taken several showers onboard including last night.  Works.

Jabsco 37202-0000 12V Light Duty Bilge Pump Shower      -181
4.5 gpm  8 ampls.   Shower sump pump with

You can access it by removing the drawer frame in the aft cabin. Make sure that the y valve hasn’t been changed to the shower sump first. Water runs downhill so priming shouldn’t be an issue.

I have had the pump out and I do sort of remember taking it apart, cleaning it all up and reinstalling it.  Seems to get a prime very quickly now.

( We couldn’t hear it over engine noise. ) Later I noticed more water in the fridge from defrosting and tried the pump again. Nothing pumped out. I correctly thought the filter might be clogged and so we removed it and cleaned it. But the pump won’t prime at all now. Thoughts?  Do I need a new pump?  Any priming tricks welcome.
