Replacing a Wax Ring
Wax rings are used to seal a toilet to the flange.
It is used to seal the water and sewer gas into the soil stack. If there
is moisture or water on the floor around the toilet, you probably need a new
wax ring. One note: Find a helper for this task. Not only are toilets heavy,
but you will need help aligning the flange bolts when you set the toilet back
in place. Please note that some localities require a plumber to perform this
activity so please check in advance.
Turn off the water to the toilet and flush it (Fig. 1). Remove the water line from the tank. Next you need to empty the
bowl. There are two ways: 1) Use a cup to empty the toilet bowl. Get as much water as possible out. 2) pour a bucket-full
of water (at least a gallon) into the bowl. Pour it in all at once.
The next step is to remove the nuts that secure the toilet to the flange (Fig. 2). The flange bolts have tabs on them so
they should not turn when you turn the nuts. If the bolts turn when you turn the nuts, you will need to saw the nuts off.
The easiest way to do this is to hold the top of the bolt with pliers (vice grips are better) and try to turn the nut a bit. This will
give you access to the body of the bolt under the nut to saw it off. Next, take a hacksaw blade, wrap a rag around one end
and saw the nut off. This will likely take some doing.
Locate the spot where you want to put the toilet when you lift it from the flange. Remember that the toilet still has
some water left in the trap and some of it may leak. A good spot to put the toilet is a tub or tile floor. Put down something
to protect the surface - it will get wet. Lift the toilet up and gently place it on its side (Fig. 3).
Remove the old wax ring from the bottom of the toilet (Fig. 4). Scrape off all of the old ring (Fig. 5). Clean the
bottom completely (Fig. 6). Next, clean the flange and the area of the floor under the toilet (Fig. 7). Get all of the old junk off
the flange. Inspect the floor and flange. If the subfloor has been damaged by the leak, stop now and call a professional
Place the flange bolts back into the slots on the flange and the wax ring on the bottom of the toilet (Fig. 8). Now comes
the part where you need help. Lift the toilet up, being careful not to set the toilet down, and place it over the flange (Fig.
9). Have your helper guide the toilet back over the flange bolts. Tighten the nuts by hand until they are snug. Now
gently tighten the nuts with a wrench (Fig. 10). DO NOT over-tighten these as the toilet may crack. Check the nuts in a few
days to make sure that they are still tight.
