5. Inspecting the Plumbing and Flange
Before installing the new toilet:

- Ensure the flange is level with the floor.
- Replace or repair the flange if necessary.
- Check that closet bolts are clean and correctly positioned.

6. Installing the New Wax Ring and Toilet Base
Proper sealing prevents leaks:
- Place the new wax ring on the flange or directly under the toilet base depending on manufacturer instructions.
- Carefully lower the toilet bowl over the flange, aligning bolts with holes.
- Press down evenly to compress the wax ring and create a watertight seal.
- Secure the bowl with nuts on the closet bolts, tightening gradually and evenly.
- Use a level to ensure the toilet is sitting flat.

Final connections:
- Attach the tank to the bowl if not pre-assembled, following manufacturer instructions.

- Turn on the water supply slowly to check for leaks.
- Flush several times to ensure proper function and that no water seeps from the base.
8. Testing and Finishing Touches
