DIY Toilet Repair: How to Replace a Wax Ring and Save Money

When it comes to plumbing emergencies, a leaky toilet is often at the top of the list. While most toilet leaks can be easily fixed, replacing the toilet wax ring is a common solution that requires a bit more effort. In this comprehensive guide, we will walk you through the step-by-step process of changing a toilet wax ring, empowering you to tackle this plumbing task with confidence.

What is a Toilet Wax Ring?

A toilet wax ring is a flexible, water-resistant seal that sits between the base of the toilet bowl and the flange on the floor. Its primary purpose is to prevent water from leaking out of the toilet base and onto the floor. Over time, the wax ring can deteriorate or become damaged, leading to leaks.

Symptoms of a Faulty Wax Ring

• Water leaking around the base of the toilet
• A wobbly toilet that rocks back and forth
• Foul odors emanating from the toilet base

Tools and Materials You’ll Need

• New toilet wax ring
• Adjustable wrench
• Plumber’s putty (optional)
• Toilet bowl cleaner
• Scrub brush
• Rags
• Bucket

Step-by-Step Guide to Replacing a Toilet Wax Ring

1. Shut off the Water Supply

• Locate the water supply valve behind the toilet and turn it clockwise to shut off the water.
• Flush the toilet to drain the tank and bowl.

2. Disconnect the Water Supply Line

• Use an adjustable wrench to loosen the nuts connecting the water supply line to the toilet tank.
• Disconnect the water line and place it in a bucket to catch any remaining water.

3. Remove the Toilet

• Carefully lift the toilet straight up and off the flange.
• Inspect the old wax ring and remove any remnants from the toilet base and flange.

4. Clean the Toilet Base and Flange

• Use toilet bowl cleaner and a scrub brush to thoroughly clean the toilet base and the flange on the floor.
• Remove any debris or old sealant.

5. Apply Plumber’s Putty (Optional)

• Apply a thin layer of plumber’s putty around the base of the flange to create a better seal.

6. Install the New Wax Ring

• Place the new wax ring onto the flange, ensuring that it is centered and facing the correct direction.
• Press down firmly on the wax ring to create a seal.

7. Reinstall the Toilet

• Lower the toilet back onto the flange, carefully aligning the bolts with the holes in the base.
• Push down on the toilet until it is fully seated.

8. Reconnect the Water Supply

• Reconnect the water supply line to the toilet tank and tighten the nuts with an adjustable wrench.
• Turn on the water supply valve and check for leaks.

9. Tighten the Toilet Bolts

• Use an adjustable wrench to tighten the bolts that secure the toilet to the floor.
• Do not overtighten the bolts, as this can crack the toilet base.

Additional Tips

• Use a high-quality toilet wax ring for the best results.
• If the flange is damaged or uneven, you may need to use a toilet flange repair kit.
• If you are having difficulty removing the old wax ring, you can use a putty knife or utility knife to carefully cut it away.
