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.
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.
There's a Loose Water Supply Line.
If there's a loose water supply line, you'll notice that the water is leaking from the base of your toilet all of the time, rather than just when you flush it. Check the connection where the supply line connects to the tank to make sure the nut and rubber seal are tight.
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.
Behind every good toilet—or, rather, beneath—is a good wax ring. But with time, even good toilet wax rings can go bad.
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.
If the leak only occurs when you flush, it means the wax ring is eroded and needs replacing. You might need to remove the toilet from the floor to access the wax ring. Wax rings are affordable, and generic ones fit most toilets meaning there's no going wrong.
🚽 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.
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.
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.
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.
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.
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.
The resulting damage caused by the Category 3 water damage resulting from a wax seal leak is covered under most homeowners' insurance policies.
The main signs of a leaking toilet may include a damp area on the floor around the bottom of the toilet, a spongy feeling in the floor at the bottom of the toilet seat, signs of dampness on the ceiling in the room underneath your toilet, or the occasional smell of sewer gas and the flooring coming up in the area around ...
If there is no caulk, any water that creeps underneath the toilet can remain undisturbed for some time. It will soon start to stagnate, providing a breeding ground for mold and fungus. The application of caulk to the toilet prevents this from happening, and the bathroom is healthier as a result.
When a toilet leaks at the base, with water pooling on your bathroom floor, it's typically due to the failure of the wax gasket that seals the toilet to the floor. This seal should make a watertight connection between the toilet and floor. A leak often means that the wax seal may need to be replaced.
Since the water flows down the sewer, leaking toilets don't necessarily leave any signs of a leak, until you get the bill. The average leaky toilet can waste about 200 gallons of water per day. That's over 6,000 gallons a month ($70.06*) for just one leaking toilet!
For instances where the flange is too low, you can raise it with a repair flange or Set-Rite Kit. It is not recommended to stack wax rings because they will not seal together and would leave a leak path between the two.
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.
