I recently bought a 1978 17' boler
and am refurbishing it...it hasn't been used in a few years, so I'm having to replace and update a lot of things.
One of my challenges is that when I put water into the original Monogram Industries 461 toilet it doesn't stay in the toilet; fortunately it goes into the black water tank that seems to be in good shape.
I'm thinking the solution might be to simply replace the flush gate valve seal, but I haven't been able to find one anywhere online that indicates it fits that toilet.
Anybody know the solution to this problem?
