Leaky Toilet Repair: A Step-by-Step DIY Guide · Step 3 of 3
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
Do I need specialized plumbing tools for this repair, or can I use common household tools?
You'll primarily need an adjustable wrench and a putty knife, which are standard tools many homeowners already possess. A bucket for catching water, sponges for drying, and possibly a utility knife for trimming the wax ring are also useful items for this project.
What are the most important safety precautions to take when disassembling a toilet for repair?
Always start by turning off the water supply completely at the wall valve and flushing the toilet to drain both the tank and bowl. When lifting the toilet tank, be mindful of its weight; it's heavy and awkward, so lifting with a helper is strongly recommended to prevent injury or damage.
The project is listed as 'beginner' and 2 hours; what are the most common challenges that might extend the repair time for a first-timer?
The most common challenges include loosening old, rusted tank bolts, which may require penetrating oil, and properly aligning the new wax ring. Ensuring the toilet is perfectly centered over the flange before seating it firmly is crucial to avoid leaks and might take a few attempts.
What are common mistakes when replacing a toilet's wax ring, and how can I ensure a proper, leak-free seal?
A frequent mistake is not completely removing the old wax and debris, or misaligning the new wax ring during installation. To ensure a good seal, thoroughly clean the flange, center the new wax ring precisely on the toilet's horn or the floor flange, and apply firm, even pressure when seating the toilet.
