Help! Why Is My Toilet Leaking? Learn the Common Causes and How to Fix It

A leaking toilet is one of the common plumbing problems in homes and commercial properties. Left unrepaired, a leaky toilet can drive up your water bills, cause water damage in your toilet, and create a thriving environment for mold growth. It’s important to learn about the common causes of leaky toilets and how you can fix the problem before things escalate.

Mr. Rooter Plumbing is a reputable plumbing contractor providing a comprehensive range of plumbing services in Dallas, including toilet maintenance and replacement. In this article, we will walk you through the common causes of a leaking toilet and how to fix it.

• A Damaged Flapper

One of the common causes of a constantly running toilet is a deteriorated or damaged flapper. This is a rubber or plastic piece that opens to allow water to flow into the bowl and then seals back up to let the tank refill. If the flapper is damaged, it won’t seal properly; hence, it will allow water to continuously leak into the bowl. A constantly running toilet is a major water waster and needs to be addressed as soon as the problem is detected.

Thankfully, replacing a damaged flapper is a simple process that doesn’t require specialized skills. Simply lift off the toilet tank and detach the chain from the flush handle lever and flapper itself. Lift the old flapper off the overflow tube and the flush valve. Position the new flapper onto the overflow tube and flush valve, and ensure it’s securely clipped in place. If you need help, reach out to a licensed plumber specializing in toilet repair.

• Loose Mounting Bolts

Is your toilet leaking at the base? The most common culprit for a toilet leaking at the base is loose mounting bolts. Your toilet should be firmly attached to the floor with two bolts. These bolts can loosen over time and allow water to seep out during each flush. A puddle of water forming around the base of your toilet after flushing is a clear indication of loose mounting bolts. You may also notice the toilet rocking back and forth due to compromised stability.

The solution to this problem is to tighten the bolts using an adjustable wrench. However, you need to consider the age of your toilet to determine if tightening mounting bolts can be a long-term solution. Call a trusted plumbing service to inspect your toilet and provide you with professional advice.

• Faulty Fill Valve

A faulty fill valve is a common culprit for a constantly running toilet. This valve controls the water flow into the tank, and if it's not functioning properly, it can cause water to continuously leak into the bowl.

To fix a faulty fill valve, you'll need to replace the entire unit. This is a relatively simple DIY task that involves turning off the water supply, flushing the toilet, and removing the old valve. Then, you'll install the new valve, connect the water supply, and adjust the float to ensure the correct water level in the tank. If you're unsure about the process, it's best to consult a plumbing repair service.
