Fix a Toilet That Keeps Running

14July 2020

This video shares several methods for fixing a toilet that keeps running. Your toilet tank has a fill valve, flush valve, and flapper. And it’s these parts that ultimately lead to the toilet running. My $116 water bill could have been prevented by simply replacing the $5 flapper.

The second way a leak occurs is when the flapper chain gets stuck between the flapper and flush valve. If you encounter this just trim the chain so that it doesn’t drape below the flapper. Problem solved.

Sometimes the water in the tank is too high. If this is the case it will run over the overflow pipe and cause the tank to refill. You need to lower the tank’s water level to about 1 inch below the overflow pipe. Watch the video for a more in depth explanation.

A toilet that keeps running is annoying, not to mention expensive. I’m sharing my tips so that you don’t suffer from a $116 water bill like me. Hopefully these tips help you with your project.

  1. can anyone help me out with this – my toilet keeps running and when it does, it sounds as if it’s flushing, but it’s not. and idk what to do?

  2. Ok so my toilet has been flooding for 2 days now which sucks and I didn’t know what to do, my toilet is very old and it dosent have that screw what do I do? It’s the problem with the water running in to that tube and I have no screw what do I do?

  3. Thank you for explaining all Three ways that could be the problem. Every other video I found only spoke of the flush valve, but it was our fill valve that was bad. Adjust the float didn’t work, but your video put us on the right track to investigate further. My 14 year old son and I watched your video, discussed what we thought was wrong, investigated, discovered it was the valve and not just the float, watched more videos, bought parts, and fixed it today! It was a good project for us to do together. Thank you.
