Step-by-Step Guide: How to Use a Toilet Flange Spacer to Correct Misalignments

A toilet flange spacer is an essential component for ensuring a secure and leak-proof connection between your toilet and the drainpipe. If you’re experiencing issues with your toilet rocking or leaking, installing a flange spacer can often resolve the problem. In this comprehensive guide, we’ll delve into the step-by-step process of how to use a toilet flange spacer, providing detailed instructions and expert tips to help you achieve a successful installation.

What is a Toilet Flange Spacer?

A toilet flange spacer is a device that fits between the toilet flange and the subfloor, raising the flange to the appropriate height for a proper toilet installation. It is typically made of plastic or metal and comes in various thicknesses to accommodate different floor heights.

When Do You Need a Toilet Flange Spacer?

You may need a toilet flange spacer if:

• The toilet is rocking or unstable
• There is a gap between the toilet base and the floor
• The toilet is leaking at the base
• The flange is too low or too high for the toilet

Step-by-Step Guide to Using a Toilet Flange Spacer

Materials You’ll Need:

• Toilet flange spacer
• Toilet wax ring
• Adjustable wrench
• Screwdriver
• Hacksaw (if necessary)

Step 1: Remove the Toilet

• Turn off the water supply to the toilet.
• Flush the toilet to empty the tank.
• Disconnect the water supply line.
• Unbolt the toilet from the flange using an adjustable wrench.
• Carefully lift the toilet straight up and set it aside.

Step 2: Inspect the Flange

• Once the toilet is removed, inspect the flange to ensure it is in good condition and securely attached to the subfloor.
• If the flange is damaged or loose, replace it before installing the spacer.

Step 3: Choose the Correct Spacer Thickness

• Measure the distance between the top of the subfloor and the bottom of the toilet flange.
• Select a spacer that will raise the flange to the desired height, typically 1/2 to 1 inch above the finished floor level.

Step 4: Install the Spacer

• Place the spacer over the flange and align the holes.
• Secure the spacer to the flange using the provided bolts or screws.
• Tighten the bolts or screws until snug, but do not overtighten.

Step 5: Cut the Spacer (Optional)

• If the spacer is too long for your installation, you can cut it to the desired length using a hacksaw.
• Cut the spacer from the bottom to avoid damaging the flange.

Step 6: Install the Wax Ring

• Apply a new wax ring to the top of the spacer.
• Center the wax ring over the flange.

Step 7: Install the Toilet

• Carefully lower the toilet onto the wax ring, aligning the bolts with the holes in the flange.
• Hand-tighten the bolts until the toilet is secure.
• Use an adjustable wrench to fully tighten the bolts, but avoid overtightening.

Tips for a Successful Installation

• Use a level to ensure the toilet is installed evenly.
• Apply a bead of silicone caulk around the base of the toilet to prevent leaks.
• Allow the caulk to cure for 24 hours before using the toilet.
• If you encounter any difficulties during the installation, consult a licensed plumber for assistance.

Troubleshooting Common Issues

• Toilet is still rocking: Check if the bolts are properly tightened. If they are, the spacer may not be thick enough. Remove the toilet and install a thicker spacer.
• Toilet is leaking: Make sure the wax ring is properly installed and that the bolts are not overtightened. If the leak persists, consult a plumber.
• Toilet is too high or too low: Remove the toilet and adjust the spacer thickness accordingly.
