Stop Your Toilet from Wobbly: The Quick and Dirty Guide to Raising Your Flange

A toilet flange is a crucial component of any bathroom, ensuring a secure and leak-proof connection between the toilet and the drainpipe. However, sometimes the flange may need to be raised to accommodate changes in flooring or to resolve drainage issues. This guide will provide a comprehensive step-by-step process on how to raise your toilet flange effectively.

Tools and Materials Required

• Toilet flange extender (flange ring or wax ring with built-in extender)
• New toilet bolts
• Plumber’s putty
• Hacksaw
• Screwdriver
• Adjustable wrench
• Measuring tape
• Level

Step 1: Measure the Flange Height

Use a measuring tape to determine the current height of the flange. Ideally, the flange should be flush with the finished floor level.

Step 2: Choose and Install a Flange Extender

If the flange is too low, you will need to install a flange extender. There are two types of flange extenders available:

• Flange ring: A metal or plastic ring that fits around the existing flange and raises its height.
• Wax ring with built-in extender: A wax ring with a plastic or metal base that extends the height of the flange.

Step 3: Remove the Toilet

Disconnect the water supply and flush the toilet to empty the tank and bowl. Remove the nuts that hold the toilet to the flange and carefully lift the toilet straight up off the flange.

Step 4: Clean the Flange and Drainpipe

Use a scrub brush and cleaner to remove any debris or old wax from the flange and drainpipe. Ensure the surfaces are clean and dry.

Step 5: Install the Flange Extender

Apply a bead of plumber’s putty around the base of the flange extender. Place the extender over the existing flange and press down firmly. Secure the extender with screws or bolts, depending on the type of extender used.

Step 6: Install the New Toilet

Place the new wax ring on the flange extender. Carefully lower the toilet onto the flange, aligning the bolts with the holes in the flange. Tighten the bolts evenly using a screwdriver or adjustable wrench.

Step 7: Level the Toilet

Use a level to check if the toilet is level from side to side and front to back. If necessary, adjust the bolts slightly to level the toilet.

Finishing Touches

• Reconnect the water supply and flush the toilet to check for leaks.
• Apply caulk around the base of the toilet to seal any gaps and prevent water damage.
• Trim any excess caulk with a utility knife.

Troubleshooting Tips

• Toilet wobbles: Ensure the flange extender is properly secured and the toilet is level.
• Leaks: Check the wax ring for cracks or damage. If necessary, replace the wax ring.
• Clogs: If the toilet frequently clogs, consider raising the flange further to improve drainage.

Flange Extender Options

• Flange ring: Available in various heights and materials, including metal, plastic, and PVC.
• Wax ring with built-in extender: Convenient and easy to install, but may not be as durable as a flange ring.
• Adjustable flange: Allows for fine-tuning of the flange height, providing greater flexibility.
