Toilets — like anything else — leak, wear out and break down. Replacing them is costly and usually unnecessary when just a little maintenance can do the trick. Here the top four toilet parts you should replace when problems arise.
1. Wax Seal
One thing separates your toilet from the sewer: an airtight, watertight wax or non-wax seal. This seal, which surrounds the toilet’s exit hole, does more than sit between the fixture’s base and flange. It’s a safety feature, and that’s why it’s one of the most important toilet parts you could replace.
The seal prevents water from leaking as it leaves the toilet and enters the drainpipe. This prevents the kind of water damage that leads to mold and mildew, at best, and rotting that, at worst, could compromise the home’s structure.
In addition, the seal prevents harmful sewer gases from entering your living space. Hydrogen sulfide, for instance, leaves foul odors, similar to rotten eggs, but that’s the least of your worries. It’s also corrosive, flammable and poisonous.
