A toilet that runs continuously is not just an annoyance—it can waste hundreds of gallons of water per month, increasing your water bill and potentially causing damage over time. Understanding the common causes of a running toilet can help you address the issue quickly and effectively, preventing unnecessary expenses and water waste. Here’s what you should know about a running toilet from Parson Plumbing and Drains, the Columbus Plumbing experts.
Common Causes of a Running Toilet
One of the most frequent reasons for a constantly running toilet is a faulty flapper. The flapper is the rubber seal at the bottom of the tank that lifts when you flush, allowing water to flow into the bowl. Over time, flappers can become warped, cracked, or coated in mineral deposits, preventing a proper seal and causing water to leak continuously. This seemingly small issue can result in significant water loss over days or weeks.

Another common cause is a problem with the fill valve or the float, which regulates the water level in the tank. If the float is misaligned, too high, or the fill valve malfunctions, the toilet may keep filling even after the tank is full. This continuous flow not only wastes water but also creates constant noise that can be disruptive in your home.
Additional issues can include a worn-out flush valve seat, chain problems that prevent the flapper from seating properly, or even cracks in the toilet tank itself. While some homeowners attempt DIY fixes, these solutions are often temporary and may not address the underlying problem, leading to recurring issues.
