My coach has been sitting for about 3 months and after filling with water last night this fitting is leaking on the back of the toilet. It's leaking from the very top which looks like a vent almost. Is this is a replaceable part? What's it called?

That is a "vacuum breaker" and should be available from the toilet manufacturer.

Thanks Mel. I'll look into it. Maybe the local RV parts place has one.

I've had to replace a couple of them. Each time I've had to order from Thetford. Easy enough to do once you figure out how to reach it. My suggestion is that if you can't easily get to the hoses "I see you're using a mirror", consider removing the toilet and do the work in the garage and then re-install the toilet.

when i replaced the bowl seals, i took the toilet out so got to know how it works... without moving the toilet, you should be able to just pull it out with force toward the back wall (horizontally). (mine is a sealand though).

You may find that locating the part is a bit more difficult than you think. It really depends on what brand and model toilet you have. Like CountryFit I have a Sealand and mine is a discontinued model. I had to replace the anti-siphon valve on ours too. And I had a devil of a time finding a supplier for my part.

I was able to replace mine with the toilet in place, although I had to do some clever manipulation of a flexible drive screwdriver to get to the hose clamps. But, once I took out the controller board I had an acceptable access to anti-siphon valve. The fact that you have to use a mirror to take a picture of yours makes me think you may not have enough access to replace it without removing the toilet from the stand. (And if you do that, you might as well replace the seals as well while you have it off.)

Don't be surprised if your replacement does not come with a cap on top. On mine, I had to take the top off the old unit and put it on the new one.

Like everything else, the first time you do it is that hardest.
