Step 1: Prepare the Area for Replacing a Toilet Flange and Wax Ring
Begin by preparing to replace a toilet flange and wax ring. Shut off the water supply valve behind the toilet by turning it clockwise. Flush to drain the tank—hold the handle down for maximum emptying—and use a sponge and bucket to remove remaining water from the tank and bowl.

Use an adjustable wrench to disconnect the supply line from the toilet tank. This step is critical to avoid water spills.

Step 2: Remove the Old Toilet
Removing the old toilet is key to replacing a toilet flange and wax ring. Pry off the plastic caps covering the base bolts with a screwdriver, then loosen the nuts with an adjustable wrench. If corroded, cut bolts with a hacksaw.
Break the Wax Seal
Gently rock the toilet to break the old wax ring seal. Patience prevents damage during removal.
Lift the Toilet
Lift the toilet straight up—it’s heavy—onto a towel or newspaper to protect your floor. This challenging step is vital for replacing a toilet flange and wax ring.

Step 3: Inspect and Replace the Flange
Inspecting and replacing the flange is central to fixing a leak when replacing a toilet flange and wax ring. Scrape off old wax from the toilet base and flange using a putty knife.

Set the Wax Ring
Center the new wax ring on the flange, a precise step for replacing a toilet flange and wax ring.
