Vacuflush vacuum breaker leak

[tonyiiiafl]

Getting a leak from the back of the vacu flush toilet. Probably had an issue over the winter, but who mows. When we step on the pedal we get water running down the supply tube. A mirror places the problem at teh vacuum breaker. Anyone ever replace one with the toilet in place? Does it just pull out and then press back in? I ordered the part and supply tube, just wondering what I am getting into.

Thanks!

Not really understanding your issue description but I did have to replace the foot pedal valve as it developed a leak. Rather easy job with just the water supply needing to be shut down and depressurised. Bought a spare which I carry on board as I do have 2 heads however the other one still has the original valve although it is the guest head which sees seldom use. I believe it is universal but do double check your model as I do not know what you have. https://www.ebay.com/itm/Complete-Domet ... SwtIdc5vcK

The foot pedal valve is OK. When stepping on the foot pedal to activate the valve, water goes up to the rear of the toilet to fill it. On the back there is a valve that is leaking. I am wondering how to replace. Does it just friction fit with a grommet? It is number 14 and 15 in the diagram. https://www.google.com/url?sa=i&url=htt ... AdAAAAABAD

The ones I've done have had Oetiker type crimp clamps on the lines but you could use regular hose clamps.

Here is a better view. https://marinesan.com/vacuum-breaker-small/ looks like a standard hose barb style so push on and clamped I have to assume.
