Safety Precautions

Before starting any repairs, ensure you have turned off the water supply to the toilet. Wear safety glasses and gloves to protect yourself from debris and harsh chemicals.

Step-by-Step Instructions

1. Remove the Toilet

• Unbolt the toilet from the floor using an adjustable wrench.
• Carefully lift the toilet straight up and set it aside.

2. Inspect the Flange

• Examine the flange for cracks, breaks, or any other damage.
• If the flange is severely damaged, it will need to be replaced.

3. Cut the Old Flange (if Necessary)

• If replacing the flange, use a hacksaw to cut the old flange flush with the floor.
• Clean the area thoroughly to remove any debris.

4. Install the New Flange (if Necessary)

• Apply PVC primer to the new flange and the pipe outlet.
• Apply a generous amount of PVC cement to the same areas.
• Quickly insert the new flange into the pipe outlet and secure it with bolts.

5. Level the Flange

• Use a level to ensure the flange is level.
• Adjust the bolts as needed to achieve the correct level.

6. Install the Wax Ring

• Place the wax ring on the bottom of the toilet base, centering it over the flange.
• Smooth out any wrinkles or creases in the wax ring.

7. Reinstall the Toilet

• Carefully lift the toilet and lower it onto the wax ring.
• Align the bolts and tighten them securely.
• Reconnect the water supply and flush the toilet to check for leaks.

Finishing Touches

• Use a utility knife to trim any excess wax ring that may have squeezed out around the base of the toilet.
• Clean up any debris and discard it properly.

Tips for Success

• Use high-quality PVC cement and primer for a strong and durable repair.
• Allow the PVC cement to dry completely before using the toilet.
• If the flange is loose but not damaged, you can tighten the bolts to secure it.
• If you are not confident in your abilities, consult a licensed plumber for assistance.

Troubleshooting

• Toilet is still leaking: Ensure the flange is level, the wax ring is properly installed, and the bolts are tightened securely. If the leak persists, you may need to replace the flange or call a plumber.
• Toilet is loose: Tighten the bolts that secure the toilet to the floor. If the toilet remains loose, check for damage to the flange or wax ring.
• Flange is cracked: Replace the damaged flange with a new one following the steps outlined above.

Information You Need to Know
