Proper cast iron toilet flange replacement. This client in Chelmsford MA. Had purchased this house from a house flipper that did some questionably un professional repairs. They retiled the bathroom floors and installed new sinks and toilets in the home. However after a short while of them living in this home the toilet was leaking into the basement. Pulled the toilet to find a very large hole under the toilet that was cut out. Someone previously must have found that the cast iron flange was rotted. So they decided the way to fix it was to force a plastic one inside the cast iron pipe, cracking the plastic too. Then spray foam the big hole to secure the toilet. Here is the proper way to install a cast iron toilet flange. We also had to add 2×4’s below the floor and cut plywood to fill in the large hole they made so the new flange was secured. This is not a homeowner handyman job people, call a professional this could have caused a very unhealthy mold problem.
