[C320-list] Shower sump won’t completely drain

[Charles Martin]

Doug, Crosby, Ken *et alii:*

Regarding my shower sump/fridge drain issue, I have checked the strainer
(it was dirty but cleaning it did not resolve the issue), and have narrowed
things down to either a lack of prime for the pump or a need to clean the
pump, or possibly a need to replace the pump.  I'll see if more head in the
fridge will lead to priming the pump.  If that doesn't work, I'll try to
remove it and clean it.  I may need to go thru the hole for the two drawers
in the aft stateroom for access.  If that doesn't work, I may replace
it--maybe there is a self-priming pump that might work better.  I'll let
you all know how it goes.  Any other thoughts would be welcome.

Best,
Chip Martin
