My house is 28 years old. It has 5 toilets. The 3" black, plastic drainage
pipes are in a slab with a steel flange popping out of the slab. They all
have the same problem:
The original builder used toilets that had a deeper than normal recess in
the area that matches with the the toilet flange. (Or maybe they figured on
putting extra thick tiles on the pad in the bathroom.) Therefore, all toilet
flanges stick out 1/2" above the concrete pad. This makes it impossible to
replace the toilet with standard toilets because the new toilets would sit
directly on the flange, leaving a 1/2" space between the bottom of the
toilet and the slab. IOW, the flange is too high. Result: the toilet
When a previous owner replaced a toilet, he inserted a 1/2 sheet of plywood
under the toilet in order to raise the toilet. It now leaks and looks like
How can I resolve this problem. Of course, I could jackhammer the pad, cut
out out the old, glued-in flange, and glue in a new, shorter flange.
With 5 toilets, that would be a major undertaking
Can someone think of a simpler solution?
