[C320-list] Holding tank replacement

Thu Mar 21 19:31:51 PDT 2024

Inspection port in a holding tank? Not for me! My 23 year old #772 has the 23 gallon black holding tank. I have replaced hose lines from head to tank, but would never consider cutting a hole in that well sealed tank. My boat came to me with exterior plated gauges for both black and fresh water. I really don't use them. The best gauges are you nose in the head for gassing and awareness of a lack of water pressure--time to fill both tanks! I always top off before a third shower.

I had one on a previous boat. Pretty gross. It also became a source for odors.

Thanks Dan,

It seems that the tank I have (not leaking) is pretty much what you get.
Has anyone out there put an inspection/cleaning port in their holding tank?
