Uh oh. You walk into your bathroom and find a puddle forming around the base of your toilet. Not only is it messy and unpleasant, but it also signals a potential plumbing problem. Suddenly, you’re worried about water damage, costly repairs, and maybe even having to replace the entire toilet.
We understand how stressful a leaky toilet can be, especially when you’re not sure what’s causing it or how to fix it. At Instant Plumbing and Rooter, we’ve been helping homeowners in Phoenix and the surrounding cities tackle their plumbing challenges for over 20 years. We’re not just about fixing leaks; we’re about providing peace of mind and ensuring you have the information you need to make informed decisions about your home’s plumbing.
So, why is your toilet leaking from underneath? Let’s dive in and explore the common culprits:
Identifying the Source of the Leak: Detective Work 101
Before you can fix a leaky toilet, you need to figure out where the water is coming from. Here are the usual suspects:
- Base of the Toilet: This is the most common source of leaks. Water might be seeping out from under the toilet bowl itself, indicating a problem with the seal or the connection to the floor.
- Tank: If the leak seems to be coming from higher up, the tank might be the culprit. Check for cracks, loose connections or a faulty flush or fill valve.
- Supply Line: The supply line is the pipe that connects your toilet to the water supply. A leak in this line can cause water to pool around the base of the toilet.
Common Causes of Toilet Leaks at the Base
- Worn-Out Wax Ring: The wax ring is a seal that sits between the toilet bowl and the floor flange (the pipe that connects to your sewer line). Over time, this wax ring can dry out, crack or become dislodged, allowing water to leak out.
- Loose Closet Bolts: Closet bolts are the bolts that secure the toilet bowl to the floor flange. If these bolts become loose, the toilet can wobble and the wax ring seal can be compromised, leading to leaks.
- Cracked Toilet Bowl or Base: A crack in the toilet bowl or base can also cause leaks. This is less common but can happen due to accidental damage or manufacturing defects.
- Clogged Drain Line: A clog in your drain line can cause water to back up into the toilet bowl and overflow. With a main sewer back up, this can dislodge the wax seal, leading to leaks around the base of the toilet.
- Damaged Flange: The flange is the pipe that connects your toilet to the sewer line. If the flange is damaged or corroded, it can cause leaks.
Other Potential Leak Sources: Don’t Overlook These!
- Leaky Tank-to-Bowl Gasket: The gasket is a rubber seal that sits between the tank and the bowl. If this gasket is damaged or loose, water can leak out during flushing.
- Loose or Damaged Supply Line: A loose connection or damage to the supply line can also cause leaks.
- Condensation: In humid environments, condensation can form on the outside of the toilet tank and drip down to the floor, creating a puddle.
The Risks of Ignoring a Leaky Toilet: Don’t Let a Small Leak Become a Big Problem
A leaky toilet might seem like a minor issue, but it can quickly escalate into a major headache if left unaddressed. Here’s why:
- Water damage and bacterial growth: Water leaks can damage your flooring, subflooring and even the structural components of your home. Excess moisture can also lead to bacterial growth, which can be a health hazard.
- Increased water bills: Even a small leak can waste a significant amount of water over time, leading to higher water bills. Last year, a long time client called because they went out of town for 2 weeks, got home and had an $800 water bill show up. This was all from a faulty toilet that was leaking while they were away.
- Health hazards: Sewage leaks can pose serious health risks due to the presence of harmful bacteria and viruses.
Troubleshooting and Repairing a Leaky Toilet: DIY or Call a Pro?
If you’re handy and comfortable with basic plumbing repairs, you might be able to fix a leaky toilet yourself. However, if you’re not sure what’s causing the leak or if the problem seems complex, it’s best to call a professional plumber.
Preventing Future Toilet Leaks: A Little Prevention Goes a Long Way
- Regular inspections: Periodically check your toilet for any signs of leaks or damage.
- Proper toilet care: Avoid flushing anything other than toilet paper and human waste. Don’t use harsh chemicals that can damage the toilet’s components.
- Address minor issues promptly: If you notice a small leak or other issue, don’t ignore it. Addressing minor problems early on can prevent them from becoming major headaches.
