RV Toilet issue

[mdoverkamp]

We have an rv and for the last few months, about every 30 days or so a black looking valve cover, I’d say it’s the size of maybe a bike tire valve (and it looks like one too) kept popping off from the back of the toilet. When it does that and you step to flush water just flows out of the back and hence doesn’t flush.

I have looked everywhere for this little piece that seems to just slip over the spigot in the back of the toilet. I’ve no idea what it’s called

Toilet pressure valve stem cover?

Generally we just pop it back on and it’s fine. This one seems to have slipped into ten vent and is gone.

I cannot find this little piece.

It fits on this piece: DOMETIC 87 MAX PRESSURE 125 PSI.

I am not looking for the entire pressure valve or whatever. I’m not very good at explaining this. ??

I went to the local farm supply store and got one that fit right from one of the widget drawers there.
