A continuously running toilet is more than just an annoyance. Left unfixed, it can dramatically increase your water bill and potentially lead to water damage or larger plumbing problems. By understanding the most common causes and solutions, homeowners can quickly identify the issue and decide whether a do-it-yourself fix is possible or if it’s time to call a professional.
The flapper in your toilet tank regulates the flow of water from the tank into the bowl. Over time, the flapper can warp, crack, or wear down, preventing it from sealing properly. This allows water to leak continuously into the bowl. Inspecting and replacing a worn-out flapper is often the simplest fix for a running toilet.
The fill valve controls how much water enters the tank after a flush. If the valve is damaged, clogged, or misaligned, water may flow when it shouldn’t, leading to constant running. Signs include a hissing sound or water trickling even after the tank should be full. Adjusting or replacing the fill valve usually resolves the issue.
Older toilets use a float ball that rises with the tank’s water level. If the float is set too high, the tank may overfill, causing water to run continuously into the overflow tube. Adjusting the float to the correct height helps shut off the water at the right level and prevents waste.
A cracked or leaking tank can also cause your toilet to run constantly as it tries to refill. Inspect the tank carefully for visible cracks or water seeping around seams. While some minor leaks can be sealed, a cracked tank often requires full replacement to prevent further issues.
A simple way to check for leaks is with a dye test. Add a few drops of food coloring to the tank and wait without flushing. If colored water appears in the bowl, you likely have a leak caused by a faulty flapper or tank issue.
Minor problems, such as replacing a flapper or adjusting the float, can often be handled with basic tools and a little DIY effort. However, larger issues like persistent leaks, broken valves, or cracked tanks require professional plumbing service. Attempting complex repairs without proper knowledge can worsen the problem and increase repair costs.
If your toilet continues to run after you’ve tried basic troubleshooting, it’s best to bring in a licensed plumber.
