How to Replace a Broken PVC Flange on a Toilet
Replacing a PVC flange on a toilet is not a complicated job. In case your toilet is not stable and is rocking, then you need to replace the PVC flange. Below are the instructions for the repair.
Tools and Materials
- PVC flange
- Wax ring
- Channel locks
- Pliers
- Screwdriver
- 2 towels
- One rag
Step 1 – Remove Toilet
Cut off the water supply to the toilet. Flush the toilet to empty the tank. There will be some water left over. Place one towel in the tank to absorb the remaining water. Unhook the water supply from the toilet with the channel locks. There will be some excess water in the line, so you can spread the other towel behind the toilet for this. Remove the nuts from the floor bolts with the pliers. Remove toilet.
Step 2 – Wax Ring
Remove the old wax ring. Use the screwdriver to loosen and pull it up with your hands. Discard.
Step 3 – Install New Flange
If needed, unscrew the screws holding the old PVC flange and remove. Insert the new PVC flange. Tighten up the screws. This will cause the rubber seal to pucker and create a water tight seal.
Step 4 – Replace Wax Ring
Apply a new wax ring by pressing down firmly on the ring. Insert the floor bolts.
Step 5 – Replace Toilet
Gently set the toilet over the wax ring and floor bolts. Tighten the floor bolts with pliers. Reconnect the water supply to the toilet with the channel locks. Double check all connections. Turn the water supply on. If everything is working properly, you have successfully replaced the PVC flange.
