Customer Questions & Answers

I'm replacing a toilet. I have a cast iron pipe face that is the same diameter as the plastic toilet flanges, so the flange doesn't screw in the floor

the issue is the flange can't be bolted to the plywood in the floor because the face plate of the cast iron drain pipe is the same size (the drain hole the standard size) but the face of the cast iron pipe is about 4" across, the same diameter and size as the plastic flange plate. The toilet mounting bolts go into the cast iron drain pipe face, which seem to be in order. Previously, the toilet was moving causing a leak to the floor below as essentially the whole bowl is only mounted to the face of the cast iron drain pipe. the question is whether there's a flange system that will work/fix this
Asked by: paul
Fluidmaster does not make a face plate or any product that would replace or repair a cast iron pipe. In most instances the plate would have to be drilled out and secured onto the exiting face place to repair any damage the former plate had. it is highly recommended to seek the advice of a Master Plumber in order to secure the pipe and toilet so no movement and more importantly no water can damage the ceiling/ floor of the home.

Customer Reviews

4 in. Wax-Free Bowl Gasket is rated 3.0 out of 5 by 2.
Rated 5 out of 5 by from Works well I replaced a broken wax seal with this. It installed easily, works well, and gives every indication that it will be much more robust than the wax seal was.
