As a result, having a local plumber replace your toilet's wax ring can be anywhere from $75-250 depending on the cost of the trip charge and whether anything else is discovered in the process that needs fixing.
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.
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. When that happens, they need to be replaced.
The first sign of a bad toilet ring is water forming around the base of the toilet. To test that a bad seal is the problem, grab a couple of towels and wipe up the water. Go on with your day, checking periodically to see if the water has returned.
In theory, the wax ring “should” last the lifetime of the toilet, or certainly 20 to 30 years. We come across situations all the time, however, where wax rings are in need of replacing well short of this scenario.
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.
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.
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.
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.
🚽 Caulking Prevents Water Contamination
It could be water splashing out of a bathtub, mop water, water from a shower and even misguided potty training from your young boys who seem to miss the toilet bowl every single time! Without caulk around the toilet base, water can get under there and sit for a long time.
Wax rings come in two diameters, 3 and 4 inches, to comply with the standard size for toilets in the United States. Thickness is also a specification that should be considered. Again, you have two options: regular and extra thick.
Wax seals are still the go-to for many plumbers. If the flange is particularly high and can't be lowered, wax might be the only option. Even the thinnest wax-free seal can't compress as effectively as wax.
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.
Wax rings are inexpensive and can be found at most hardware stores. Make sure you have a few essential tools on hand before you start the replacement: an adjustable wrench, a putty knife, a bucket, disposable gloves, and a towel or paper towels.
How soon after I install a new toilet can I use it? Technically, a new toilet will work as soon as it's hooked up to the water supply line. But waiting until the caulk is fully dry is wise. Refer to the directions on your caulk tube for an ideal dry time, but know that most should be set within three to six hours.
Plunging down too hard
A hard thrust downward can break the wax seal between the toilet and the floor, causing a leak.
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.
The wax ring seals a toilet base to the toilet flange. If during installation the wax is squashed out such that it partially blocks the waist opening that can cause clogging.
International building codes require that a fixture shall be made watertight where it comes in contact with the wall or floor. One way of making sure this code is adhered to is by caulking around the toilet.
Standard wax rings are about ¾- or 1-inch thick. This standard size is suitable for flanges which are set slightly above, at the same level as the floor, or slightly below the flooring (up to ¼ inch).
