I redid an older mobilehome that has central H/Air in the floor (under the flooring)
I replaced my floor in the bathroom and installed the toilet. You could flush all day long with out any water on the floor, but, if you turn on the central heat for a long while
( several hours ) you come back to about 8 T/spoons of water at the base.????? huh ???
I have replaced the wax seal several times with the same results.
