How to Repair a Broken Toilet Flange with a Repair Ring · Step 2 of 6
In this video
With the toilet removed, use a putty knife to scrape the old wax ring off the flange. Inspect the flange area. In this case, the original cast iron flange is found to be completely rotted and broken, sitting well below the finished floor level. The previous installer had used plastic spacer rings to build up the height, but these are not a proper or watertight fix. Remove any screws holding the spacers and pry the spacers off to fully expose the rotted flange.
Goal: Remove old wax and spacers to inspect the flange
- The old wax is sticky and messy. Scrape it onto a piece of newspaper for easy disposal.

FAQs
The project is rated 'beginner' but has a 4-hour estimate. What makes it beginner-friendly, and what contributes to the time needed?
This project is beginner-friendly because it doesn't require specialized plumbing skills, just careful step-following and patience. The 4 hours account for draining/removing the toilet, thorough cleaning of the flange area, precise repair ring placement, and careful reinstallation with a new wax seal, especially for first-timers.
Are all the listed tools absolutely necessary, or are there any I might already have that could serve as alternatives?
Essential tools include an adjustable wrench for water lines and bolts, a drill for securing the repair ring, and a putty knife for scraping off old wax. While specific brands are listed, generic versions of these tools are usually sufficient. A sturdy bucket and sponges are also critical for water management and cleanup.
What are the most common pitfalls or mistakes DIYers make during this repair, and how can I avoid them?
A common mistake is not thoroughly cleaning the old flange area, leading to poor adhesion or an uneven seal. Another is improperly seating the new wax ring or overtightening closet bolts, which can crack the porcelain base of the toilet. Ensure the flange is dry and level before installing the repair ring, and tighten bolts gradually and evenly.
What are the key safety precautions I should take when removing and reinstalling a heavy toilet?
Always shut off the water supply to the toilet and flush to empty the tank and bowl as much as possible before attempting removal. Toilets are heavy and awkward, so lift with your legs or get help from another person to avoid back injury. Wear appropriate gloves to protect against unsanitary conditions and potential sharp edges from the broken flange.
