Step by Step Instructions

Turn off the water.

Step 1:

Turn off the water supply to the toilet.

Drain the toilet.

Step 2:

Drain the toilet by giving it one last flush, then, with a rag or towel, soak up the remaining water out of the tank. If necessary, push any remaining water in the bowl down with a plunger.

Remove the old toilet.

Step 3:

Remove the old toilet. Start by removing the bolt caps and unscrewing the nuts. Then unscrew the water line. Rock the old toilet back and forth to break up the old wax ring and caulk.

Remove the wax ring.

Step 4:

Remove the wax ring with a putty knife. It may also be a good idea to place a rag or towel in the opening to prevent any old wax from falling in and to eliminate odor. Scrape up any remaining caulk with the putty knife.

Install the new toilet.

Step 5:

Install the new toilet. Start by placing the new wax ring in place. Then line up the bolts with the new toilet’s bolt holes. To create a secure connection with the wax ring and toilet, place gentle-to-moderate pressure down on the toilet.

Secure the new toilet.

Step 6:

Secure the new toilet. Make sure the toilet is level before completely securing it down. When tightening the bolts, alternate from bolt to bolt to prevent cracking.

Hook up the water.

Step 7:

Hook up the water. After securing the water line, turn the water to the toilet back on, and flush the toilet to test the connection.

Caulk the bottom of the toilet.

Step 8:

Create a watertight seal around the bottom of the toilet with the caulking gun.
