Water puddling where your toilet meets the floor. If you notice water pooling at the base of your toilet and don't see anything dripping from the toilet tank, there's a good chance the flange is the problem.
When this happens, you might notice your toilet seems loose or you might get leaks or sewer odors. In addition, if the flange is the wrong height, this can also cause major problems for your plumbing. If the flange is too short, then it leaves a gap where water, waste, and odors can escape.
Flanges last for about 5-20 years. Worn-out flanges will no longer create a tight seal between the toilet and outflow pipe. As a result, when you flush, the toilet will leak at the base. By replacing the closet flange you will be able to stop the base from leaking.
Any loose flange bolts or saturated bolt holes may cause a water leak, but not as many as your wax rings would. The wax ring affects all surrounding components. If the wax ring is worn out, it may allow water to flow into the flange's outer layers, including toilet bolts.
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.
Water around the Toilet Base
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.
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.
Replacing a toilet flange costs $145 to $165 on average. However, that's assuming no other complications pop up. Your costs could easily run into the hundreds or even thousands if a broken toilet flange is difficult to remove, or if you have excessive water damage.
Of course, the obvious answer is to tighten the bolts again and proceed with your operations. However, it's important to consider the method by which you tighten the bolts, as well as how often you need to tighten them. Torquing is the typical method of tightening bolts when they become loose.
Can you put a new toilet flange over an old one? A standard toilet flange should fit snugly into the outflow pipe and sit level with the subfloor. Installing a new one without first removing the old one will make it impossible to form a seal and keep the toilet bowl bolted securely in place.
$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.
If your toilet leaks, there's a good chance that a broken toilet flange is to blame. The flange is the metal coupling on top of the wax ring that secures your toilet to the floor and seals the connection between the toilet and sewer pipe. If either piece becomes worn or broken, you'll likely have a leak on your hands.
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.
As a rule of thumb, try a turn or two a side until you feel resistance, them try to wiggle the toilet bowl slightly. If there is no significant movement, you are probably tight enough. This tightening operation is a "feel" thing you get from experience, so be conservative and use your best judgement.
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.
A damaged wax ring doesn't seal the connection between the toilet and sewer line. This causes water to leak out and pool around your toilet. If you catch this issue quickly, then it may not damage your subfloor and require additional repairs. Some leaks are constant, while others only occur when you flush the toilet.
For instance a $2.00 compressed gasket may last 1 – 5 years, but a more expensive gasket such as a $25.00 Kammprofile gasket could last 20 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.
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.
In conclusion, the wax ring on your toilet will most likely never need to be replaced for the lifetime of the toilet. But, it will if you find that the base of your toilet is leaking. Sometimes, leaks at the base can be caused by the bolts being too loose. On the other hand, it could be because of a faulty wax ring.
Whenever you remove a toilet for any reason, you will need to replace the wax ring seal between the toilet and the toilet flange (sometimes called a closet flange) attached to the floor. A wax seal is used because it resists mold and bacteria and retains its sealing ability after years of use.
