A bad or poor wax seal on your toilet is among the most common reasons for a toilet leak. There are many reasons why the wax ring may not seal right, but perhaps the most common one is that you simply have an old wax ring that must be replaced with a new wax ring.
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.
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.
🚽 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.
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.
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.
An improperly installed wax ring may leak. Perhaps the installer used a ring that wasn't thick enough, or perhaps the flange is high enough to lift the toilet off the floor and make it rock. Once water begins seeping through a compromised wax ring, it won't stop. It doesn't take standing water long to rot a subfloor.
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.
$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 first sign of a failing wax ring is water that seems to be seeping out of the base of your toilet. Other signs to look for include: Water stains on the ceiling from the floor below. A lingering, unpleasant bathroom odor from escaped sewer gasses.
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 and Toilet
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.
One reason for a toilet leak from the base might be a loose connection where the tank meets the toilet. Check the connecting bolts. If they seem loose or you can see water gathering in that area, use the screwdriver to tighten them. Approach the bolts from inside the tank and screw downward to create the best seal.
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.
Loose Flange Bolts
The solution is to tighten the bolts by hand until the toilet stops rocking. If the bolts are too damaged, you'll have to replace them.
If the caulk is beginning to break down, it is a good idea to remove the old and apply the new caulk. What type of caulk for toilet base? It is recommended that you use a silicone base caulk due to its waterproofing capabilities. Let's take a look below at how to caulk our toilet base.
Caulk prevents smell
Yes, the bathroom is a place to get clean, but it can easily be a place to trap some pretty foul smells. 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.
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. If you'd rather have something that's easy to install, then a modern, wax-free toilet seal might be a better choice.
