The next step involves removing the supply line by using an adjustable wrench. You will need a container that should be close to you for the water drained from this hose.

After loosing the bolts with the help of a wrench, the toilet will be lifted and put aside on a pile of rags.

Once the toilet is put away from its base, the wax ring can be seen, so the plumber can remove it from the flange using a putty knife. As he or she can remove the wax ring, the debris and residues accumulated around the flange will also be removed.

At this point, when the wax ring is removed, the plumber can inspect the flange to make sure that it is working in proper conditions. If there is a problem with this piece, they will recommend replacing it. The cost to replace the flange would be around $520.

After this check, the plumber will install the new wax ring on the face of the flange or at the base of the drain, depending on the toilet type.

Once the toilet wax ring is replaced, the whole toilet will be reinstalled and thoroughly checked so there will be no moving or wiggling.

Finally, the bolts are tightened at the toilet base and the water source reconnected in order to fill the toilet water tank again.

Important things to consider

The lifespan of a high-quality toilet wax ring is up to 25 years or equal to the life of the entire toilet as this piece would not get damaged very easily. Anyway, to avoid the water toilet leaks due to improper wax ring installation it must be tightly fixed with the bolts holding the toilet to the floor base. The seal can be compromised by loose bolts, resulting in damage to the toilet wax ring.

If are going to replace the toilet wax ring yourself, firstly make sure you purchase the right size for the flange, as these are not all equal. Also, in some setups, a flange extender may be required.

Usually, the wax rings come in a standard size, but some of them are double in thickness. This type is used if the toilet flange under the toilet is below the floor level.
