How to remove a broken toilet flange yourself
Removing a stuck or broken toilet flange is difficult because it anchors the toilet firmly to the floor and often breaks during removal, leaving homeowners unsure whether to patch it with epoxy or attempt a full replacement. This uncertainty leaves the bathroom out of commission and forces a decision between continuing a tricky DIY repair or calling a professional plumber.
