Types of Toilets

There are various types of toilets, each with distinct installation procedures. The most common types are the two-piece toilets, one-piece toilets, and wall-mounted toilets. Recognizing your toilet type will guide you in selecting the right replacement and comprehending the installation process.

The Process of DIY Toilet Replacement

Follow this step-by-step process to execute a swift and successful toilet replacement.

Step 1: Remove the Old Toilet

The first step in toilet replacement is to remove the old toilet. Start by shutting off the water supply and emptying the tank and bowl. Unscrew the water supply line and bolts that hold the toilet to the floor. Lift the toilet carefully and move it aside.

Step 2: Clean the Toilet Flange

Use a putty knife to scrape any residue from the old wax ring. Inspect the flange for any cracks or damage. If necessary, replace it before installing the new toilet.

Step 3: Install New Toilet

Mount the new wax ring onto the toilet flange. Position the new toilet bowl over the flange, aligning the mounting holes with bolts. Press it downwards to compress the wax ring for better sealing. Attach the tank, secure it with bolts, and connect the water supply line.

Finally, turn on the water supply and allow the tank to fill. Flush the toilet to check for leakages and proper functionality.
