Step-by-Step Guide to Replace Toilet Flange Concrete Floor
1. Safety First
Before you begin, put on safety goggles and a dust mask to protect yourself from flying debris and dust.
2. Remove the Old Toilet
Turn off the water supply to the toilet and flush to empty the tank and bowl. Disconnect the water supply line and unbolt the toilet from the floor. Carefully lift and remove the toilet.
3. Remove the Old Flange
Use a chisel or hammer drill to carefully chip away the concrete around the old flange. Be careful not to damage the subfloor. Once the concrete is removed, use a pry bar to gently pry the old flange away from the floor.
4. Clean the Area
Use a utility knife to remove any remaining debris or sealant from the floor. Vacuum or sweep away any dust or loose particles.
5. Install the New Flange
Place the new toilet flange over the hole in the floor. Use a level to ensure that it’s level both horizontally and vertically.
6. Seal the Flange
Apply a generous bead of toilet flange seal around the base of the flange. Press the flange firmly into place, ensuring that the seal makes contact with the floor.
7. Patch the Concrete
Mix a small batch of concrete patch mix according to the manufacturer’s instructions. Apply the mix around the flange, filling in any gaps or voids. Smooth the surface with a trowel.
8. Install the Toilet
Once the concrete patch has set, you can reinstall the toilet. Align the toilet with the flange and carefully lower it into place. Bolt the toilet to the floor and reconnect the water supply line.
9. Apply Plumber’s Putty
Apply a ring of plumber’s putty around the base of the toilet where it meets the flange. This will create a watertight seal.
Troubleshooting Tips
- The toilet won’t sit flat on the floor: Ensure that the flange is level and that the concrete patch has set properly.
- The toilet wobbles: Use shims or washers to level the toilet and eliminate any movement.
- Water is leaking from the base of the toilet: Check the toilet flange seal and plumber’s putty for any gaps or tears.
