Water Leaking: If you notice water pooling around the base of the toilet, it could indicate a failing wax ring. This is often the most obvious sign. Unpleasant Odors: A wax ring that has deteriorated can allow sewage gases to escape, leading to foul odors near the toilet.
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.
If the floor has any softness or if the toilet flange is broken then there can be movement between the toilet and drain flange every time someone sits on the toilet. Over time this slight movement causes wax ring to fail.
The cost to replace a wax seal on a toilet typically ranges from $50 to $150, including both parts and labor. Here's a breakdown of the costs:
Bad Odors Coming from the Toilet
It's likely that what you're smelling is sewer gas that's made it past the wax ring. Don't mess around with this type of situation. Sewer gases are harmful. Not only do they make people sick, but if there is an open flame, the gases could cause an explosion.
If a wax seal is stored in a dry location exposed to temperatures between 70°F and 110°F, the shelf life is five years from the date of manufacture. Once installed, a wax seal should last the life of the toilet, 20 or 30 years, without needing to be changed.
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.
Wax-free Toilet Seals: The New Kid on the Block
For plumbers interested in a mess-free option, wax-free toilet seals check this box. These seals affix to the toilet using a strong adhesive. There's no wrangling the ring in into place. It's a straightforward method of keeping your toilet base leak free.
If you see pooling water around your toilet's base, clean up the water and thoroughly scrub the tiles until they are clean and dry. Wait a few minutes before reevaluating the space for leakage. If the pooling water returns after you clean the area, you probably have an under-tile toilet leak.
If you've ever installed a toilet, you know how important obtaining a proper seal is to the integrity and cleanliness of a bathroom. While there are many taboos plumbers should avoid when setting toilets, none are as frowned upon as double stacking wax toilet rings.
The average homeowner typically replaces their toilet every 10 to 15 years. However, when properly cared for, a toilet can last up to 50 years or longer. Toilets usually show signs that they need a repair or replacement, but some reach the end of their lifespan with little or no physical signs.
Plunging can usually only loosen clogs that are close to the bowel. What's more, if you're too vigorous with your plunging, you might mess dirty toilet water out of the bowel. Besides this, too much plunging can also damage the wax ring at the base of your toilet.
The wax rings are probably misaligned. The fix is to reseat the toilet using a flange extension and one wax ring. The slight unevenness of the slab might be a contributing factor, but you can fix that by shimming the bottom of the toilet so that it sits level. Toilet hydraulics are pretty simple.
When removing a toilet, replacing the wax ring between the bathroom and the floor-mounted toilet flange (commonly referred to as a closet flange) is essential. The wax ring's purpose is to create a water and air-tight seal that can withstand years of use.
Reasons to Caulk Around a Toilet
Moisture Prevention: Without caulk around the toilet base, external water can seep under the toilet, leading to floor and subfloor damage over time. This is especially important in bathrooms with wooden floors, as prolonged exposure to moisture can lead to rot and structural issues.
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.
The International Plumbing Code requires caulk around the base of a toilet. You must use 100% silicone caulk where fixtures meet the wall or floor. Here are a few of the primary reasons it's required, and you should take the time to properly seal toilets above and beyond basic code requirements.
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.
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.
Both toilet tank gaskets and toilet tank bolts can leak. The bolts hold the tank onto the toilet while the gasket creates a seal between the tank and toilet where the water leaves the tank when the toilet is flushed. In some cases, leaks in this area can be fixed by tightening the tank bolts.
If wax does start to age, you may notice discoloration or yellowing of the wax itself, and/or a rancid smell due to the aging of the oil. If this occurs, we would recommend doing a test candle to check the performance and throw of your products before continuing to use the wax.
If you notice the caulk around the base of your toilet start to turn brown, it means your toilet has a wax ring which is leaking. As a result, human waste especially urine is decolorizing the normally white caulk. The solution to this is to remove the toilet and put a new wax ring.
