The Most Common Causes of a Toilet Leak

While toilets are relatively low-maintenance, they can cause significant stress when they break down. Leaks are an especially pesky issue, posing health and safety risks and damaging your home. Even the smallest leaks can lead to big problems. The sooner you call a plumbing specialist, the more trouble — and money — you’ll save yourself. This article explores the most common causes of a toilet leak and how a plumbing repair service can help.

Damaged Flapper

You may not have heard it by name, but you’re definitely familiar with your toilet’s flapper. This plastic or rubber cap lifts when you press down on the lever to flush. As it lifts, it releases water from the tank and into the bowl, replenishing it with fresh water to prevent bacteria or stains. It also acts as a sealing barrier, preventing water in the tank from escaping. This simple device is essential for a clean, functional toilet.

When the flapper warps or breaks, water can escape into the bowl, often creating a light trickling sound. This is known as a “silent leak.” You may not notice this sound, but you’ll notice the high water bills it causes. Pay attention to your toilet after you flush, and if you hear trickling once it fills, call a plumbing specialist for toilet repair.

Cracked Supply Line

A cold-water supply line refills the tank with water after every flush, ensuring your toilet is ready for the next use. If this line cracks, water leaks onto the floor and can even cause severe flooding, leading to structural damage and stained walls. The sooner you call a plumbing repair service to complete leak detection and toilet repair, the better your chances are of avoiding significant home damage.

Damaged Tank

If you notice puddles around your toilet, there’s a good chance you have a damaged or cracked tank. This is the large container behind the bowl that holds water, transferring it into the bowl after each flush before refilling itself. Since it holds a lot of water, if it cracks, it can cause significant leaks, leading to water damage and bacteria growth. A plumbing leak repair specialist can reseal your tank or replace it for a long-lasting solution.

Rusted Fill Valve

Another common source of leaks is a rusted fill valve, which controls the amount of water used to refill the tank. When this valve rusts, it can’t function with the same accuracy, causing the tank to overflow. This can cause water to splash onto the floor or create subtle leaks down the tank’s back. A plumbing repair service can replace your fill valve to keep your toilet working optimally, only filling as much as is needed and no more!

Bowl Damage

Toilet bowls are far from indestructible, and over time, the porcelain or ceramic walls can crack, causing unhealthy water waste to leak onto your floor. Unfortunately, sealing these cracks with putty won’t cut it and will only prolong the unhealthy situation and high water bills. If your toilet bowl cracks, it’s essential to call a professional plumbing repair service to complete leak detection and toilet repair. You’ll have to replace the entire toilet, and plumbing specialists can recommend the best models for your home and your budget.
