Why Your Toilet Won't Stop Running and What You Can Do About It

Why Your Toilet Won't Stop Running and What You Can Do About It

It's late at night, you've gone to bed and finally found some peace and quiet after a long day, but then you hear a consistent noise – it's your toilet running continuously. This is a common plumbing issue that most homeowners have experienced. If your toilet won't stop running, it can waste a lot of water and add to your water bill. But don't worry, there are a few things you can do about it.

Find the problem

First, it's essential to know what is causing the problem. Your toilet may not stop running due to various reasons. One of the most common culprits is a malfunctioning flapper. The flapper is a valve at the bottom of the tank that prevents water from continuously draining into the bowl. If it's not sealing correctly, water will keep flowing into the toilet bowl, causing it to run continuously.

Faulty Fill Valve

Another possible cause is a faulty fill valve. The fill valve controls the water flow that refills your toilet tank after you flush. If the fill valve is not working correctly, water will continuously flow into the tank, causing your toilet to run.

Blocked Chain

Another common reason your toilet won't stop running is a blocked or kinked-up chain. Check to see if the chain is attached correctly between the flapper and the handle. If it's too long, it will tangle up, preventing the flapper from closing completely, causing the toilet to keep running continuously.

Water Level in the Tank

You can also check the water level in the tank. If it's too high, the water will keep spilling over into the overflow tube and continually flowing into the bowl, causing your toilet to run continuously. You can adjust the water level by adjusting the float arm to ensure the water level in the tank is not too high.


A running toilet is not just annoying; it can lead to a waste of water and add to your water bill. The good news is that this problem is often easy to fix.
