Common Causes of a Leaking Toilet: Part Two

 Common Causes of a Leaking Toilet: Part Two

A leaking toilet can become a major problem if left untreated, resulting in costly repairs or replacement, water damage, and a high monthly water bill.

Often, we don’t realize how vital our toilet is until it’s no longer functioning. One of the major causes of a malfunctioning toilet is water leaks. Leaking toilets often start as small leaks that can be gross and inconvenient. However, a leaking toilet can become a major problem if left untreated, resulting in costly repairs or replacement, water damage, and a high monthly water bill. Listed below are four common causes of a leaking toilet.

Faulty or Misadjusted Toilet Float

A toilet float, often called a float valve or ballcock, is a device responsible for regulating water levels in your toilet’s tank, filling it up without overflowing. If you’re experiencing issues with overflowing water in your toilet’s tank, it’s probably the result of a faulty float, or your toilet’s float needs to be readjusted. Fortunately for homeowners, the float is relatively easy and affordable to replace and adjust in most toilets.

Running Fill Valve

If you’re experiencing an overflowing toilet and it’s not a result of the float, it’s probably the fill valve. The fill valve and float work together to control the amount of water flowing into your toilet’s tank. A fill valve that won’t shut off is often a result of old age, rust, mineral deposits, clogs, damaged seals, and many more factors causing a leaking toilet. Before attempting to repair or replace your toilet’s fill valve yourself, you should seek assistance from a skilled plumber.

Damaged Toilet Bowl

Another cause of a leaking toilet is a cracked or damaged toilet bowl. Although toilets are durable and built last a long time, if any structural part of your toilet bowl is damaged or leaking, it’s best to replace the entire toilet to prevent future leaks.


Like most plumbing fixtures, your toilet is composed of many parts that have connectors with seals to prevent water leaks. Over time these connectors can become loose, damaged, cracked, or lose their seal, causing water to leak from your toilet.
