Does your toilet keep running long after you’ve flushed? A constantly running toilet is a common plumbing problem for homeowners across Southern California. Not only is the sound annoying, but a running toilet can waste up to 200 gallons of water a day — dramatically increasing your water bill. Understanding why your toilet keeps running is the first step toward saving water and money. In this guide, the experts at A-1 Performance Rooter and Plumbing explain the most common reasons behind this issue and how professional toilet repair in Los Angeles, Long Beach, and Orange County can fix the problem fast.
Common Reasons Your Toilet Keeps Running
Toilets have several moving parts that control water flow. When one of these parts fails, your toilet won’t stop running properly. Here are the most frequent causes:
1. Faulty Flapper
The flapper is a rubber seal that controls the flow of water from the tank into the bowl. Over time, it can wear out, warp, or become dirty, preventing it from sealing properly.
- Solution: Inspect the flapper for damage or buildup. If it looks worn, replace it — a simple fix that often stops the toilet from running.
2. Misadjusted Float
The float controls the water level inside your toilet tank. If the float is set too high, water continuously flows into the overflow tube, causing the constant running sound.
- Solution: Adjust the float to lower the water level. For older toilets with ball floats, simply bend the arm slightly downward. For newer models, adjust the float cup mechanism by turning the screw or sliding the adjustment clip.
3. Worn-Out Fill Valve
Another common cause is a failing fill valve, especially in older toilets. When the fill valve can’t shut off properly, it continues to let water flow even after the tank is full.
- Solution: Test the fill valve by pushing down on the toilet float while water is running. If the water stops, the valve is the problem and should be replaced.
4. Leaking or Cracked Overflow Tube
If the overflow tube is damaged, water continuously leaks into the bowl. This not only wastes water but can also indicate larger wear issues inside the tank.
- Solution: Inspect the overflow tube for cracks or corrosion. A professional plumber can replace the tube and check internal seals to ensure everything functions efficiently.

Preventative Toilet Maintenance Tips
To avoid running toilets in the future, consider these maintenance tips:
- Inspect the flapper every 6–12 months for signs of wear or buildup.
- Check the water level inside the tank; it should be about an inch below the overflow tube.
- Avoid using bleach tablets in the tank, as they can deteriorate seals and rubber components.
- Schedule annual plumbing inspections with a local professional for long-term reliability.
