[C320-list] Toilet Related

[Dave Hupe]

Note that on older hulls (like my #32) there is an anti-siphon loop for the toilet, but it does not extend up into my medicine cabinet.  It is accessed by removing the medicine cabinet (easy remove 4 screws and pull out the whole cabinet).

New toilets are often supplied with a hose that goes directly from the pump to the bowl. Independent of the question of whether to replace the existing hoses, the question here is whether it is okay to use this hose as supplied or whether the hoses "that run behind the head wall" are required.

Those hoses are part of an anti-siphon loop that goes up into the cabinet above the toilet. The purpose is to make sure that if the head inlet valve is open then water cannot siphon into the boat should the heal angle be sufficient to bring the toilet below the water line (and water for some reason flows through pump unchecked). It's a good safety precaution and I think it would be a good idea to keep the loop in place, even if you replace the hoses.

You can see the design in the Catalina drawing that I extracted from the 320 manual here: https://pages.adrianba.net/c320/HoldingTankAndHead.pdf

I learned this when I contacted Catalina Direct to find out what a new holding tank will cost since I had to remove the holding tank to get to the lower tank hose and remove it only after the tank could be lifted out of its location. I replaced all hoses and the holding tank because the new replacement holding tanks have much thicker walls. Also, I also purchased thicker odor resistant head hoses instead of the former thinner rubber hoses that are prone to emitting odors as they age.

Absolutely replace all lines since you are hull #118.
I replaced all my toilet and waste tank lines to try to eliminate odors. Dave Hupe C320 #32Holland, MI

And now that I have everyone?s attention?. :)

I am planning to replace the toilet on my C320.  The current toilet has a leak in the pump and for an extra $100 I thought I would just replace the whole thing rather than just the pump assembly.  Also, I can now get a standard size bowl vs. a compact sized toilet currently installed.

There seems to be a hose running from the flushing pump outlet tail to the toilet that goes through the back of the head rather than straight across like the one supplied with the new toilet.  Can I just use the new line or should I connect the existing lines that run behind the head wall?  Is there a reason for that configuration that I?m missing?  This is a standard Jabsco marine toilet.

Are there any other gotchas to doing this seemingly simple swap (I know, famous last words?the easiest of jobs always turn into complications of the unexpected variety when it comes to boat maintenance).

Thanks!
