VacuFlush leaking from fitting at rear of unit

[Danny Troy]

I had a leak for a while now and after attending to all other minor stuff on the boat, this hopefully is the last job for a while. I took the photo using a mirror. It leak seems to be where the part enters the porcelain toilet. Wondering how to remove it and what part is actually needed. Is the whole part needed, or is there a seal that needs replacing? I'll call Dometic tomorrow, but thought maybe someone here had experience with this. Thanks for any help.

I’d just replace, if this is your part, please verify, then super inexpensive. Only .035 of a boat dollar!

Regarding removal, I believe it just pulls right out. I was removing The whole toilet to replace seals, ball, little bolt thingy, and you literally just pull towards the rear gently and it slides out...

Yes, I just found a guy on YouTube who had the same exact leak. Looks like it the grommet that holds the vacuum breaker in. Since the vacuum breaker is ok and it's only the grommet leaking, I'll try a quick fix with 3M 5200 and see if that seals it. Looks like the grommet isn't available separately, so I'll start with the free fix!

Well, if this works this will be one of the all time easy boat repairs. No tools needed! Just cleaned the surfaces and used the quick set 3M 5200 (or is it 5400?) and put it back together. I'll wait a day or so to check for leaks. Sorry for the out of focus photo.

That is supposed to be removable, I’m concerned the 5200 has made it permanent?

The grommet is available... I bought a couple in 2019.

At my age this repair will probably outlive me!
