What Does a Toilet Installation Involve?
A proper toilet installation is more than tightening bolts—it requires precise alignment, sealing, and plumbing expertise. Here’s what professionals handle:
- Removing the old toilet: Safely disconnecting the water supply and lifting the unit without damaging the flange or flooring.
- Inspecting the drain and flange: Crucial in older Houston homes where corrosion and uneven flanges are common.
- Placing the wax ring: Ensures a watertight seal to prevent leaks and sewer odors.
- Setting and securing the new toilet: Proper alignment and bolting to prevent rocking or shifting.
- Connecting the water supply: Ensuring leak-free operation and consistent flow.
- Testing and cleanup: Verifying flush performance, checking stability, and sealing the base neatly.
