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.
Toilets often have wax rings at their base. These rings create a tight seal between the base of the toilet and your plumbing system. They keep your toilet watertight and prevent the escape of noxious and potentially harmful sewer gases. However, sometimes these rings get damaged or break.
According to the International Plumbing Code (2012 edition) and the Uniform Plumbing Code (2009 edition), sealing the joint where fixtures meet the floor is required. Failing to caulk your toilet could result in noncompliance with these codes, which may lead to issues during home inspections or resale.
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.
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.
While wearing gloves, remove the old toilet wax ring. Using a putty knife, scrape the old wax seal off the toilet's base and toilet flange. Next, scrape the caulk off the toilet bowl and finished floor. Before installing a new toilet wax ring, inspect the toilet flange for any cracks or decay.
It's essential to have a good seal so that waste and water would not leak from the base of your toilet. If your toilet is leaking, the wax ring likely needs to be replaced. On average, it costs between $200 and $250 to replace a toilet wax ring.
Once installed, a wax seal should last the life of the toilet, 20 or 30 years, without needing to be changed. There are times, though, when the wax ring needs to be replaced, such as when your toilet begins to leak around the base or starts rocking. What ingredients are in wax gaskets?
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.
Plunging down too hard
A hard thrust downward can break the wax seal between the toilet and the floor, causing a leak. And a really hard thrust could even crack the bowl.
Alternatives like caulk strips and sealant tape need more frequent replacement, but spray foam and silicone putty can offer a similar life span in the right conditions.
It's actually required by the International Plumbing Code to caulk a toilet to the floor, and now knowing the reasoning behind it, why would you not want to? It helps to create safety in the bathroom and even provides sanitary protection.
All these signs point to a possible leak around the toilet flange — the metal or plastic ring that connects the toilet to the waste pipe. Toilet leaks typically occur in one of two ways: clean water dripping from the tank, or dirty water seeping out through the bottom and saturating the flooring.
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.
It is recommended they be replaced every three to five years. If you notice your toilet seal has started to loosen from the base of the toilet or on the floor, you should replace it. A torn or loose toilet seal will leak water from the tank and go down the wall or under the floor.
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.
Wax Ring: Replacing a wax ring costs $50–$200. This part seals the toilet base to the floor drain. Plumbers use plates to examine and replace this part. Tank: A toilet tank replacement costs $50–$100.
Replacing the wax ring is as easy as sliding the new piece onto the bolts in the floor, then sliding the toilet down to make a tight seal. However, many people try to lower the toilet by themselves and end up setting the ring unevenly.
If you're installing a new toilet, you'll want a new wax ring, so you can discard the old one. Inspect the flange for damage. A broken flange will need to be replaced when installing a new toilet.
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.
Some problems require expensive, complicated repairs. If you encounter these issues frequently, scheduling a replacement will most likely be the most cost-effective solution, as you can save money.
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.
