How to Replace a Broken Toilet Flange · Step 2 of 6
In this video
First, assess the broken ABS toilet flange to understand the extent of the damage. In this case, the slot for one of the toilet bolts is split, compromising its ability to hold the toilet securely. Prepare the repair by gathering a replacement flange ring and the necessary fasteners. A rag should be stuffed into the drainpipe to block sewer gases and prevent tools from falling in.
Goal: Assess damage and prepare repair area
- Plugging the drain pipe is an important step to prevent unpleasant sewer gases from entering the room and to stop debris or tools from falling into the plumbing.

FAQs
Is this "intermediate" project doable for a DIY beginner, and is the 6-hour estimated time realistic?
While rated intermediate, a patient beginner can tackle this project by carefully following each step. The 6-hour estimate is achievable if the old flange removes easily and no extensive subfloor repairs are needed, but it's wise to plan for potential delays, especially for a first-timer.
Besides the listed items, are there any other crucial tools or materials I should have on hand for this toilet flange replacement?
Absolutely. Ensure you have buckets and old towels to catch residual water from the toilet, and a shop vac can be invaluable for cleaning up debris and standing water. Depending on your old flange, a hacksaw or oscillating tool might also be useful for its removal, and a level is essential for ensuring the new flange is properly set.
Why is "Subfloor Assessment and Preparation" listed as a key step, and what specifically should I look for?
Inspecting the subfloor around the drain is critical to ensure a stable, level base for the new flange and toilet. Look for any signs of water damage, rot, or weakness in the wood. If the subfloor is compromised, it must be repaired or replaced before installing the new flange to prevent future leaks and ensure the toilet sits securely.
What is the most critical step to ensure a watertight seal and prevent future leaks after replacing the flange?
Proper installation of the new wax ring and ensuring the new flange is securely mounted at the correct height relative to the finished floor are paramount. Ensure the PVC primer and cement are applied generously and allowed adequate cure time for a strong bond. When setting the toilet, press down firmly and tighten the toilet bolts evenly without overtightening to avoid cracking the bowl.
