How To Replace a Toilet - Step-by-Step Guide

7/27/2023 (Permalink)

Replacing a toilet may seem like a daunting task, but with the right tools and a little know-how, you can successfully complete this home improvement project. Whether you're looking to upgrade your bathroom or need to replace a malfunctioning toilet, this step-by-step guide will walk you through the process of replacing a toilet and ensure a smooth and successful installation.

Step 1: Turn Off the Water Supply

Locate the shut-off valve behind the toilet and turn it clockwise to shut off the water supply. Flush the toilet to drain any remaining water from the tank and bowl. Use a bucket and sponge to remove any excess water in the bowl and tank.

Using an adjustable wrench, disconnect the water supply line from the bottom of the toilet tank. Be prepared for a small amount of water to drip, so keep the bucket handy to catch any spills.

Step 2: Remove the Toilet Tank

Loosen the nuts on the bottom of the tank using a wrench or screwdriver. Carefully lift the tank off the bowl and set it aside. If there is any remaining water in the tank, pour it into the bucket.

Remove the caps covering the bolts at the base of the toilet. Using a wrench, unscrew and remove the nuts from the bolts. Gently rock the toilet bowl back and forth to break the seal between the bowl and the floor. Once loose, lift the bowl straight up and place it on a towel or old newspaper to prevent any water or debris from spilling.

Step 3: Clean the Wax Ring and Flange

Remove the old wax ring from the flange on the floor using a putty knife. Clean any residue or debris from the flange to ensure a smooth and secure seal for the new wax ring.

Place the new wax ring onto the flange with the tapered side facing up. Insert the closet bolts into the slots on the flange, making sure they are positioned evenly and aligned with the holes in the toilet bowl.

Step 4: Position the New Toilet Bowl

Carefully lower the new toilet bowl onto the wax ring and align it with the closet bolts. Apply even pressure to compress the wax ring and create a watertight seal. Once in position, sit on the bowl or press down firmly to secure it.

Place the washers and nuts onto the closet bolts and tighten them by hand. Use a wrench to further tighten the nuts, being careful not to overtighten and crack the toilet bowl.

Step 5: Install the Toilet Tank

Place the rubber gasket onto the flush valve opening at the bottom of the tank. Carefully lower the tank onto the bowl, aligning the bolts with the corresponding holes. Secure the tank to the bowl by tightening the nuts underneath.

Attach the water supply line to the fill valve on the bottom of the toilet tank. Use a wrench to tighten it securely, but avoid over-tightening.

Step 6: Test for Leaks and Adjust

Turn on the water supply valve and let the tank fill. Check for any leaks around the base of the toilet, the water supply connection, and the tank. Use a level to ensure the toilet is sitting evenly, and make any necessary adjustments by tightening or loosening the nuts and bolts.

By following these step-by-step instructions, you can confidently replace a toilet and enjoy a functional and efficient bathroom fixture. Remember to exercise caution, take your time, and pay attention to detail throughout the process. If you encounter any difficulties or feel unsure about any step, don't hesitate to consult a professional plumber for assistance. With a little effort and the right tools, you'll have a brand-new toilet installed and ready to use in no time.
