The point where the elbow joint from our flushometer meets the toilet bowl has begun leaking (dripping, really) whenever we flush (so, whenever water passes through it). I jiggled it a bit and the elbow joint popped right out. So the connection seems to be an unthreaded pipe with a plastic gasket that slides into a threaded mounting ring (is that the right term?) that then threads onto the toilet. update: it's a slip joint nut
The gasket appears to be intact, so I think I can fix this by reinforcing the seal at the threading. I have a jar of pro-dope, a tube of durst pipe thread compound and a roll of what teflon tape.
Am I on the right track here? and Which should I use for the best seal?
PS. What is a flushometer? Ours is a Sloan Gem for a "back spud bowl" (vs. a "top spud bowl") -- it reaches the toilet via an elbow rather than a straight pipe. Our toilet is a ways out from the wall so the joint has been extended by about 8".
Update: not using the toilet wasn't really working for us so I took a stab at using pro-dope and re-assembling.
Here's the halfway point, after I unscrewed the
mounting ring slip joint nut:
And the after:
You can kind of tell from the after image that the toilet and the flushometer aren't properly aligned so the elbow joint doesn't meet the toilet at a proper 90° angle.
That worked, but there was still a tiny bead of water making its way out with every flush. I thought I'd be clever and get someone stronger than I to tighten the
mounting ring slip joint nut. Bad idea: as I was watching him tighten the mounting ring I could see the flange inlet spud assembly start to turn. We tried flushing again and tons of water came out all around the flange inlet spud assembly. So now my question is, do I have to replace the flange inlet spud assembly to fix this? We tried backing the mounting ring slip joint nut back out, but that didn't help.
