How to Replace a Broken Toilet Flange · Step 3 of 5
In this video
With the new subfloor in place, install a new toilet flange. Apply ABS glue generously to the inside of the sewer inlet pipe and the outside of the new flange's coupling. Firmly press the new flange into the sewer inlet, ensuring it sits flush on the subfloor. Align the flange so the mounting channels are at the 3 and 9 o'clock positions. Secure the flange to the new subfloor by driving deck screws through the provided holes.
Goal: Plumbing Fixture Installation
- Work quickly after applying ABS glue, as it sets fast.
- Ensure the flange is level with or slightly above the finished floor height for a proper seal.

FAQs
How long does a toilet flange replacement typically take for a DIYer?
This intermediate DIY project usually takes between 2 to 4 hours to complete, assuming no major complications. Factors like severely rotted subfloor or rusted bolts can extend the timeline, so allocate extra time if you anticipate these issues.
What are the absolute essential tools and materials I need for this job if I don't have everything on the list?
You will absolutely need an adjustable wrench, screwdriver, putty knife, and a level. For materials, a new DANCO Perfect Seal Toilet Wax Ring with Bolts is critical, and a new toilet supply line is highly recommended to prevent future leaks.
What are the most important safety precautions I should take when replacing a toilet flange?
Always shut off the water supply to the toilet and flush it to drain the tank and bowl completely before starting. Wear gloves to protect against unsanitary conditions, and use caution when lifting the toilet as it is heavy and can be awkward, potentially causing back strain or damage.
What's a common mistake beginners make when installing a new flange, and how can I avoid it?
A common mistake is not ensuring the new flange is level and at the correct height, flush with the finished floor. This can lead to an improper seal with the wax ring and subsequent leaks. Use shims if needed to achieve a perfectly level and secure installation.
