Would ideally like to use wax-free toilet seals (from Fluidmaster, Fernco, etc).
Fluidmaster seal, ready to drop the toilet into the flange.
However, have a lead (Pb) soil pipe/riser (approx 7"L, with cast iron flange, it connects to copper 90 deg. elbow). Has a 4" diam. opening at the top and looks like it starts to taper about 1/2 way down the length where it eventually necks to 3" diam at the elbow. Walls of lead pipe seem substantially thick, so assume they would not expand over time???
Some of the mfg's warn against using these wax-free seals with lead pipe. However, the pipe walls are substantial. Can't imagine them expanding/leaking. Has anyone had any experience using the wax-free inserts with this type of soil downpipe? Will the taper in the pipe internals prevent o-rings from sealing properly? Have attached 2 photos (closet flange, looking down into pipe; and picture of lead downpipe from below in basement). Assume this is typical closet plumbing from the late '60's?
Comments/Experience? Thank you.
