Identifying the Damaged Wax Ring
Identifying a damaged wax ring can be a straightforward process if you know what signs to look for. The first indication is often a foul smell coming from the toilet area. The wax ring, which forms a seal between the toilet and the sewer flange, may have deteriorated and allowed sewer gas to escape. Another telltale sign is water seeping from the base of the toilet, around the flange. This indicates a leak in the seal, causing water to seep onto the floor or subfloor.
You can also check for a damaged wax ring by rocking the toilet back and forth. If the toilet wobbles excessively or moves side to side, it suggests that the wax ring is not holding the toilet securely to the flange. This movement can weaken the seal and allow leaks to occur.
If you suspect a damaged wax ring, it’s essential to address the issue promptly. A faulty wax ring can lead to unsanitary conditions, water damage, and costly repairs. Replacing the wax ring is a relatively simple plumbing task that can be completed in a few steps by following the instructions provided in the next section.

Applying the New Wax Ring
Now it’s time to apply the new wax ring. Wax rings come in various materials, including plastic, rubber, and foam. The type you choose will depend on the specific toilet and your preferences.
Step 1: Clean the Flange and Toilet Base
Before applying the new wax ring, clean the toilet flange and the bottom of the toilet bowl thoroughly. Remove any old wax residue or debris using a putty knife or a coarse brush.
Step 2: Dry the Surfaces
After cleaning, allow the flange and toilet base to dry completely. This will ensure a proper seal when the wax ring is applied.
Step 3: Apply the Wax Ring
There are two types of wax rings: compression ring and non-compression ring.
**Compression Ring:** This type of wax ring has a conical shape that compresses when the toilet is set in place. It is typically made of a durable material such as polyurethane.
**Non-Compression Ring:** This type of wax ring is typically made of rubber or foam and does not compress when the toilet is set in place. It simply forms a seal between the toilet and the flange.
Step 4: Align the Toilet Bowl
Place the new wax ring on the toilet flange, centering it carefully. Make sure the wax horn is pointed toward the drain pipe.
Step 5: Set the Toilet Bowl
Gently lower the toilet bowl onto the wax ring, aligning it with the bolts. Do not force the toilet down or rock it back and forth. If it does not fit properly, lift it up and adjust the wax ring as needed.
Step 6: Tighten the Bolts
Once the toilet is properly seated, tighten the bolts that secure it to the flange. Be sure to tighten the bolts evenly and securely, but do not overtighten them. Overtightening can crack the porcelain or damage the wax ring.
Step 7: Check for Leaks and Adjust
After the toilet is bolted down, flush it to test for leaks. If you notice any leaks around the base of the toilet, it may indicate that the wax ring is not properly seated or the flange is damaged. In this case, you may need to lift the toilet again and adjust the wax ring or replace the flange.
Repositioning the Toilet
Step 7: Reattach the Toilet to the Flange
Once the new wax ring is in place, carefully lift the toilet back onto the flange. Align the holes in the base of the toilet with the bolts protruding from the flange. Slowly lower the toilet, making sure that it sits evenly on the wax ring. Do not overtighten the bolts; hand-tightening should be sufficient.
Step 8: Reconnect the Supply Line and Flush Valve
Reconnect the water supply line to the fill valve. Open the water supply valve to fill the tank. Once the tank is full, check for leaks around the base of the toilet and the connection between the water supply line and the fill valve. If there are any leaks, tighten the connections as needed.
Next, reconnect the flush valve chain to the handle and flush the toilet. Check for leaks around the base of the toilet and the connection between the flush valve and the tank. If there are any leaks, tighten the connections as needed.

Step 5: Install the New Wax Ring
Place the new wax ring over the base of the toilet flange, centering it evenly. Gently press down on the ring to secure it.
Step 6: Reposition the Toilet
Carefully lift the toilet and align it over the wax ring. Slowly lower the toilet into place, ensuring it sits evenly and flush with the floor.
Step 7: Reconnect the Water Supply Line
Tighten the nuts on the water supply line to reconnect it to the fill valve and the shut-off valve. Ensure the connections are secure but not overtightened.
Step 8: Turn On the Water
Turn the water shut-off valve counterclockwise to restore the water supply to the toilet.
Step 9: Check for Leaks
Checking for Leaks:
Once the water is turned on, examine the connections for any leaks. Tighten the nuts if necessary. Flush the toilet several times and observe the base of the toilet and the connections for leaks.
If you detect any leaks, turn off the water supply again and retighten the nuts or call a plumber for assistance.
