It requires no maintenance and can last 30 or more years, often as long as the toilet itself. But sometimes wax rings can dry out, crumble, and fail prematurely.
Every toilet in your home has a wax ring connecting it to your plumbing, which creates a waterproof seal to keep what goes down to the sewer from seeping out the sides. This piece of equipment usually lasts as long as the toilet, about 30 years.
or certainly 20 to 30 years.
Besides leaking, signs that the wax ring may need replacing could be an odd odor seemingly stemming from the area where the toilet meets the floor, or if the toilet itself feels wobbly.
No Leaks Coming From the Toilet
Again, leaky water is a telltale and common sign of a bad wax ring. If you do not regularly see moisture or puddling water under your toilet, you may be fine. Leaks can, however, happen where you do not see them, under the finished floor and into the subfloor.
Your toilet's wax ring creates an airtight seal to prevent water and sewer gas from escaping. When the thick wax ring goes bad, you need to replace it right away to prevent leaks. Knowing the signs of wax ring failure helps you spot an issue early to prevent major plumbing repairs.
There are, however some things that may cause them to no longer function properly. One very common cause of wax ring problems is loose toilets. If the toilet is not firmly mounted, or gets loose to the point where it rocks a bit, it can cause the wax ring to lose its seal.
The most common place for a toilet to leak is at the wax seal. Replacing a wax seal may be as cheap as $50. Other common leak points are the tank and bowl which may cost $300 or more to repair.
In your situation, it sounds like the floor has been build up around the flange and it is lower than the floor so they have to put multiple wax rings so the toilet seals down to the flange or use the rubber extension flange. These techniques generally work.
The choice between wax toilet seals and wax-free toilet seals ultimately comes down to your personal preference. Many professionals stick with wax because they know it's reliable, and they're paid to deal with the mess. If you're more comfortable with the tried-and-true approach, go with a wax seal.
Wax-free toilet seals are made out of a heavy duty rubber, so they're flexible enough to shimmy into the flange without smearing a wax ring. Wax-free seals can also be reused. As long as they're still attached to the bowl in good condition, you can reinstall the toilet without replacing the seal.
Place the wax ring on the closet flange, not on the toilet. Pick up the toilet and set it evenly over the closet flange, making sure the bolts come through the bolt holes in the toilet base. Fine-tune the toilet position, so it's right where you want it, then push it straight down so it smashes the wax evenly.
Underneath the toilet tank, locate the two plastic nuts that hold the tank to the bowl. Tighten both of the nuts. Dry off the toilet and observe to see if this stops the leak. If not, you'll need to replace the tank-to-bowl gasket.
Signs of a Toilet Leaking
Both are typical signs that the wax ring that seals the toilet to the drain may be old or worn out. This is a common problem when toilets have aged over years. The first thing you do if your toilet is leaking at the base is stop using it.
An argument that one could make for wax-free seals is that they're reusable. If you need to remove the toilet base with a wax ring, you'll need to purchase another ring to reinstall the toilet. When you use a wax-free seal, it's reusable as long as it's in good condition.
In an effort to dislodge whatever is clogging the toilet, many homeowners get overzealous and thrust too hard downward into the toilet with their plunger. A hard thrust downward can break the wax seal between the toilet and the floor, causing a leak. And a really hard thrust could even crack the bowl.
The wax ring usually needs to be replaced because the toilet is loose. The other reason why a wax ring may need to be replaced is that it has been worn down over the years and is no longer pliable. This means the seal is no longer intact. Therefore, it causes water to seep through the base.
$90-$120 is a good ballpark.
If you are having other plumbing work done, they might do it cheaper, and if they have a large travel fee, you may pay closer to $150. Unless there is a problem, it should take them under a half hour, whereas, it might take a novice 1.5-2 hours.
The most common toilet leak is caused by a deteriorated flush valve (flapper) at the bottom of the toilet tank. If the flapper does not seat properly, water will leak into the toilet bowl. Often this leak will occur without being heard.
If the wax ring isn't sealed correctly, it can cause wastewater to leak from the bottom. Leaking water can lead to mold around the floor. A poorly sealed wax ring can also cause foul odors to stink up your bathroom. If you smell sewage or see water leaking, then you may need a new wax ring.
If the closet flange sits below the level of the finished floor or the wax ring is installed catawampus, the seal can be incomplete, and the toilet will leak. Removing and resetting the toilet properly will stop the leak. To remove the toilet, shut off the water to the tank.
The wax ring is exactly what it sounds like: a ring made of sticky wax that helps form a watertight seal between the bottom of the toilet and the sewer pipe. It requires no maintenance and can last 30 or more years, often as long as the toilet itself. But sometimes wax rings can dry out, crumble, and fail prematurely.
