Toilet That Keeps Running
Water cycling in the tank long after the flush.
Quick answer
Not an emergency, but it is quietly expensive. A toilet that runs continuously can waste hundreds of gallons a day, and it is almost always a cheap part inside the tank.
A running toilet is the most common plumbing fault there is and one of the least urgent, which is exactly why people live with it for months. The waste adds up on the water bill far faster than most people expect.
How you know this is it
- Water still cycling in the tank long after the flush
- A hiss or trickle from the toilet with nobody near it
- Having to jiggle the handle to make it stop
- A water bill creeping up with no change in use
- Visible water running down the inside of the bowl
What usually causes it
- A worn flapper no longer sealing, which is the usual answer
- A fill valve that does not shut off properly
- A float set too high, sending water down the overflow tube
- A chain too short or too long, holding the flapper open
- Scale from hard water on the flapper seat, common around here
