A constantly running toilet is loud and wasteful, often requiring plumbing repairs. If you experience this issue, a few components might be damaged. Check out the list below for some of the most probable causes and how to troubleshoot them.

Why Is Your Toilet Running Constantly?

1. Failing Flush Valve

Problems with the flush valve, also known as the flapper seal, are some of the most common causes of constant running. This component regulates the flow of water from the tank to the toilet bowl. If it becomes old or dented, water may start to run longer than necessary.

To determine if you need to replace yours, put a drop of food coloring in the tank. If it ends up in the bowl without you flushing, the seal isn’t working and needs to be replaced.

2. Leaking Fill Valve

After you flush your toilet, the fill valve replaces the water in the bowl. When this tube leaks, it doesn’t have access to enough water to refill the bowl quickly. This can cause the toilet to run constantly as it attempts to address the under-filled bowl.

Take a look inside the tank and make sure the valve sits above the water level. You can also check for cracks or dislodgement, which would cause it to sink. Call for plumbing repairs if you discover damage.

3. Aged Flush Handle

When you push the flush handle down, it should come back up immediately. If it remains engaged for a long period, your toilet will keep running and wasting water and energy.

This usually occurs when a flush handle is old or corroding. A professional will loosen the handle to stop the sticking and replace any corroded parts. If necessary, they may install an entirely new flush handle.
