The pipe in my bathroom for the toilet is not high enough so that when I flush the toilet the water leaks out the back.. even a wax ring doesn't hold the water in.. I tried that already.. is it possible to put another pipe into the pipe.. like a closet flange so it would raise the waste pipe so the toilet doesn't leak..
This is a very old house... the toilet is actually set in marble with the wood floor around it.
Thanks
