2016 CC19 question on freshwater system


Mar 30, 2023
I finally was able to replace the rotted hose on the freshwater wash down hose. So, I figured I'd test it out...I put several gallons of water into the tank, turned on the switch and could hear it running, but nothing came out of the hose. So, there could be several reasons for this. Maybe the small amount of water I put in, wasn't enough. Solution would be to put a LOT of water in...but this then raises the question: what if the problem is that the pump is bad? Then I have a full tank of water I can't dump (or is there a way to drain the water)?

Anyway, hoping someone can answer these questions so I can decide how best to proceed:

1) how large is the freshwater tank on the CC19?
2) is there a way to drain the tank, or is the only way via squirting it out via the hose?
3) where is the water pump and how do I access it if it needs to be replaced?

Most on board freshwater systems have a filter in line from the water tank feed line to the pump. Normally attached to the feed side of the pump.

If no filter is present I would suspect a blockage prior to the pump due to the pressure switch most pumps have. If the blockage were after the pump the pump would shut off eventually due to pressure build up.

Or the pump is bad
