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.
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.
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.
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. When installed, a wax ring is compressed to fit the flange and the toilet, creating the seal.
The only-when-flushed toilet leak could be caused by loose mounting bolts or a worn-out wax gasket while the all-the-time leak could be caused by a loose water supply line connection, a problematic water shutoff valve, or a faulty seal between the toilet tank and its base.
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.
Remove the hassle out of replacing your toilets wax seal with Fluidmaster Better Than Wax. This superior solution eliminates messy wax, and cuts down on repair time, with a rubber toilet seal design.
Do not be tempted to stack up two wax rings because this setup tends to leak. Installing a flange extender or using an extra-thick wax ring will work much better in the long run.
$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.
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.
A wax ring, when correctly installed, produces a watertight seal between discharge hole and the waste pipe. 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.
Determine if the Wax ring is possibly bad by inspecting the floor for water or a foul odor of sewer gas. Use food coloring. If are unsure of where water is coming from you can add food coloring to the toilet tank. If the floor's water is the same color, then you likely will need to install a new wax ring.
When it works properly, the wax ring creates a watertight seal between the toilet base and the drain pipe. Unfortunately, wax can fail over time, leading to water leaking onto the floor. The good news is that popping on a replacement wax ring will fix the problem.
I have installed a few toilets over the years and have always placed the wax ring on the toilet, then placed the toilet over the flange, carefully aligning the holes with the "wobbly" closet bolts. This is the way recommended in the current new toilet's installation instructions.
Wax Toilet Seals: Keeping with Tradition
For years, wax rings have been plumbers' go-to options for making these types of toilet repairs.
A regular wax ring is all you need if the flange is set on top of the finished floor. Oatey® Heavy Duty Wax Bowl Ring can be used to set any floor type closet bowl. A thicker wax ring is used when the flange has already been set on the subfloor and is flush with the tile instead of sitting on top of it.
Thickness – Check the toilet flange.
If the flange is level with your floor, a regular-thickness wax ring will be fine. You'll only use a double-thickness wax ring if the flange is located under the floor.
Replacing the wax ring is as easy as sliding the new piece onto the bolts in the floor, then sliding the toilet down to make a tight seal.
Caulk prevents smell
If you don't caulk a toilet to the floor, you could find yourself smelling leftover residue from smelly mop water, tub water, or even worse, the remnants of your son's potty training.
Drain Size
Most waste lines have a 3- or 4-inch diameter. Many wax rings are compatible for both sizes, but it's still prudent to double-check the compatible drain size before buying a new product. To determine the correct wax ring size for your toilet, you'll need to remove and measure the base.
