Toilet Flange Too Low
Posted by Mike Janowiak on November 05, 2001 at 13:33:19:
I had water damage to my bathroom floor and pulled the toilet and replaced the plywood flooring around the toilet flange. The wax ring looked uncompressed when I pulled the toilet. Though the flange was installed above the sub-floor (diagonal planking) it appears that the flange was installed flush with the plywood flooring which lays over the subfloor.

Was the low flange and uncompressed wax ring the source of the leak and resulting water damage?

I am planning to install ceramic tile which would result in the flange being 1/2" to 3/4" below the level of the floor.

Is there such a thing as a flange extension or spacer to raise the level of the current flange to the normal 1/4" or 1/2" above the level of the floor after the installation of the new floor?
