Back flush toilet

[akpolaris]

I have a back flush head in my shop. It leaks when it is flushed. I had a plumber install it so I have not taken it from the wall to figure this out yet. Research shows me that it has some type of fiber gasket instead of a wax ring (like a floor evacuating unit). With wax rings and floor mounts some times you can double up on the ring if necessary to get a good seal. Any ideas on this situation? Does this ring come in thicker diameters??

Who makes it, and what model is it? There are a few different systems it could be.

Ok, a traditional floor mounted back-flush with a pressure assist. That mounts using a standard wax ring (the manufacturer recommends one with a horn), but from what I've heard, pressure assist toilets can have enough water velocity to cause issues with wax rings. The horn helps with that, and so can a fiber reinforced wax ring.

My problem with fiber reinforced wax rings is that they're hard to fully squash, and they don't squash as well as ordinary wax, so they can be their own worst enemy when it comes to sealing.

Personally, I've given up on wax entirely, and am only using reusable products now. Like this:

I would suggest you give their 800 number a call tomorrow, and see what they have to say about rear mounting their product. If not the FluidMaster Better than Wax, there are other products out there (the SaniSeal has known issues, but maybe the Danco Perfect Seal's hybrid wax/silicone would be better for you).

Thank you very much. I just learned way more here than on the website and you tube
