Toilet Leak

[Papahoosh]

Hello all! We have a 2020 337 RLS with a Thetford toilet. It started leaking from the top of the back only when the pedal is partially depressed. In searching thru previous posts here we are thinking that it is the vacuum breaker. Is there any other issue that would cause this? And for those who replaced the vacuum breaker would you please share a link of what we should purchase?
Does anyone know where I could find the toilet model number?

I think I need part this part.

Thank you so much!

You are probably on the right track suspecting the vacuum breaker We had a leak on our 337 in the same place... I lucked out as it turned out to be that the hose wasn't fully pushed on the vacuum breaker. Putting the hose the rest of the way on and using an aircraft-style hose clamp fixed it. The vacuum breakers are a frequent failure point, though.

The toilet is mostly likely an Aqua-Magic Style II. I think you've found the right part on Amazon - I found this one:

Thanks Rob, that is the part I was going to get.
Hey what size aircraft hose clamps did you get?

I don't remember - I had a small assortment in my junk tub and just used one of those. Sorry.
