I have had two plumbers in to install and re-install an American Standard Cadet 3 toilet. Neither installation has been successful. Is there something special about how this toilet has to be installed? (This is one that is fully enclosed at the base.)
The plumber mentioned that the waste pipe was too low below the floor, and possibly in extending it, he left a gap. Seems that two different installations would have had that problem, and a little unlikely that both plumbers didn't do the extension correctly. But maybe that's the issue.
One other point that may be contributing. Initially, this bathroom was just stubbed out, without any fixtures. When the waste pipe was initially installed, the builder did not include a vent. When installing a septic system, a vent was added to the waste pipe on the outside of the house about 7 feet from the toilet, in the waste pipe between the toilet and the septic tank. The vent comes out toward the upper surface of the waste pipe, then an immediate 45 degree bend to a horizontal section about 3 feet long, then a 90 degree elbow turns the vent upward. Currently the vent is not extended through the roof, but ends with a one-foot vertical section. Could any of this be contributing to the problem?
Thanks for your help!
If may have need two wax rings if the flange was too low.
One wax ring only works if the flange is above the finished floor.
If you have a lav in the bathroom, that should be vented, even if it's an AAVthis bathroom was just stubbed out, without any fixtures.
Then you will need at least one vent going through the roof, and extending at least six inches above it.
There is no excuse for the builder putting indoor plumbing in a structure without properly disposing of sewer gas from a septic tank. Was he just lazy and cheap?
