A running toilet can be frustrating and wasteful. While it might seem like a small issue, it can significantly increase your water bill if left unchecked. In this blog, we’ll discuss the most common causes of a running toilet, how to diagnose them, and some straightforward solutions.
1. Faulty Flapper
One of the most frequent culprits of a running toilet is a faulty flapper. The flapper is the rubber piece that seals the toilet tank after each flush. Over time, it can wear out, preventing a proper seal, and water continuously leaks into the bowl.
To fix a faulty flapper:
Turn off the water supply to your toilet.
Drain the tank by flushing.
Remove the old flapper and replace it with a new one from your local hardware store. This quick repair will help resolve many cases of running toilets.
2. Misaligned or Broken Chain
Another common issue is the chain that connects the flapper to the flush lever. If the chain is too short or long, it might prevent the flapper from closing fully, which leads to continuous running.
Solution:
Adjust the length of the chain so that there is a slight slack when the flapper is in the closed position. If the chain is broken, replacing it with a new one is inexpensive and easy to install.
3. Faulty Float or Incorrect Water Level
The float controls the water level in the toilet tank. If it’s set too high, water will overflow into the overflow tube, causing the toilet to run. Alternatively, if it’s too low, your toilet might not flush properly.
Steps to Fix:
Check the float: Adjust it so that the water level sits about an inch below the top of the overflow tube.
For older toilets with ball-and-arm floats, you can bend the arm down to lower the water level.
Newer models use a cylinder float, which can be adjusted by sliding it up or down on the shaft.
4. Issues with the Flush Valve
The flush valve is responsible for releasing water into the toilet bowl when you flush. If this valve is damaged, it can cause the toilet to run continuously.
To resolve flush valve problems:
Turn off the water supply and drain the tank.
Replace the flush valve if it’s worn or cracked.
5. Cracked Overflow Tube
A cracked overflow tube can lead to water constantly flowing into the toilet bowl. Over time, this wear and tear can result in a running toilet.
How to Fix:
Inspect the overflow tube for cracks or damage.
Replace the tube if necessary by purchasing a replacement kit.
6. Mineral Buildup in the Fill Valve
Hard water can cause mineral deposits to build up in your toilet’s fill valve, obstructing its function. This often leads to filling problems or slow leaks.
To solve this issue:
Turn off the water supply.
Clean the fill valve to remove any mineral buildup.
If cleaning doesn’t work, replacing the fill valve can resolve the problem.
Additional Issues that May Lead to Running Toilets
Toilet Gasket Replacement
A worn-out gasket can also lead to a running toilet. The gasket forms a seal between the tank and the bowl, and over time, it can degrade, allowing water to leak.
Solution:
Replace the gasket with a new one to restore the seal and prevent leaks.
Low Water Pressure in Toilet
Low water pressure might prevent the toilet from refilling quickly after a flush, which can sometimes cause the toilet to run as it tries to compensate for the pressure loss.
Tip:
Check your water pressure by adjusting the valve supplying the toilet. If you suspect deeper plumbing issues, consider consulting an emergency plumber to address possible pressure problems.
Clogged Toilet
Though typically associated with overflows, a clogged toilet can sometimes trigger issues like continuous running if the clog causes improper flushing.
Fix:
Use a plunger or toilet auger to clear the clog. For severe blockages, you might need the help of professional plumbers.
Flushing Problems
A running toilet can sometimes occur due to general flushing problems, especially when there is a miscommunication between the parts. Whether it’s a mechanical issue or a clog, flushing problems can exacerbate running toilet issues.
Solution:
Regular maintenance of flushing mechanisms and quick action in addressing clogs will keep these problems at bay.
Preventing Future Toilet Repairs
To avoid recurring issues with running toilets, it’s a good idea to inspect your toilet components regularly. Keeping an eye on the flapper, float, and flush mechanisms can prevent wear and tear from turning into expensive water bills. Additionally, addressing leaks promptly ensures that your toilet remains in good condition.
