|The what's and where's of a manual Marine toilet|
which I found very helpful - from Nigel Calder's book
Boat Owners Mechanical & Electrical Manual
In the last post, after attempting (& failing) to fix leaks, tired parts and an apparent block in our Raritan head (toilet) with vinegar and a new pump assembly, we re-wound to the beginning, & dismantled the whole toilet. What we found was the source of the remaining leak; a warped ring where the bowl attaches to the base. According to Raritan, this is the result of a hard freeze. It must have been leaking for awhile, since the bolts on the base left corroded water tracks & rust stains on the floor leading into the shower basin.
|After removing the new pump assembly & the toilet bowl, |
we discovered another source of leaks: a warped base,
likely from a deep freeze during Florian's history on the East Coast
We also found mineral deposits inside the toilet bowl flush holes around the rim, so the whole bowl was brought home to soak in a vinegar bath for three days while we waited for a new raritan toilet base to arrive.

|After reading about minerals and calcification growing in |
marine sanitation hoses where sea water pools, I traced our hoses, looking
for low points and up-angles where that might occur.
A sailing friend who does a major overhaul on his boat toilet every year told us we might be able to dislodge some of the calcification from the interior lining of the discharge hose by lightly tapping the length of the hose where it was accessible with a hammer. We did that - gently - and pulled another cup or so of grit and mineral chips out of the hose. After re-assembling the hoses and head, on the new base, and pumping a test flush, we still had backwash, bubbles and a handle that popped back up from internal pressure in the lines.
