A constantly running toilet can be more than just a nuisance at home. It can also waste hundreds of gallons of water each day, resulting in higher water bills. Here are a few reasons why your toilet may be running and what you can do to fix this issue.
Common Causes Of A Running Toilet
These are the most common causes of a constantly running toilet.
1. High Water Level In The Tank
When the water level in the tank is too high, it can allow water to constantly flow into the overflow tube. This issue will keep the toilet running.
It can also indicate a problem with the fill valve or incorrect adjustments.
2. Faulty Flapper
The flapper is a plastic or rubber component located inside the toilet. Its main purpose is to lift when flushed and seal the tank as it refills.
As time goes on, the flapper can wear out. This can result in water continuously leaking into the bowl.
3. Issues With The Chain
The chain that connects the flush lever to your flapper can get tangled or stuck, in some cases. If the chain is too short, it could keep the flapper from sealing properly.
Meanwhile, if the chain is too long, it can become trapped under the flapper.
4. Float Malfunction
The float is a mechanism that both rises and falls with your water level. This component tells the fill valve when to stop adding water.
If the float is damaged or placed too high, the water may keep running constantly.
5. Fill Valve Problems
The fill valve is responsible for controlling waterflow into the tank.
When the valve is either misaligned or worn, the tank may not refill properly. This can result in an endless flow of water to the toilet.
How To Fix A Running Toilet
There are a few steps you can take to fix the issue of a constantly running toilet. Take the following steps outlined below.
Step 1. Inspect Your Flapper
- Lift your tank lid and find the flapper at the bottom of the tank.
- Make sure the flapper seals correctly and does not appear to be damaged.
- If the flapper seems worn, you can purchase a replacement and install it as an easy DIY project.
Step 2. Adjust Water Level
- Check the water level in your tank.
- If it’s reaching the top of the overflow tube, make sure to adjust the float to ultimately lower the level.
- Depending on the specific type of float system, you may need to turn a screw or bend the float arm to make this slight adjustment.
Step 3. Check The Fill Valve
- Check the fill valve for any visible issues.
- If it is not shutting the water off efficiently, you may need to clean it or replace it.
- Thankfully, replacing the valve is a straightforward task.
- However, it’s always a good idea to contact a local professional if you have any questions.
Step 4. Chain Test
- Make sure the chain connecting the flapper and the flush lever is neither too loose nor too tight.
- Adjust its length at this time.
- It should not interfere with your flapper’s ability to seal the tank.
Step 5. Inspect The Float
- If the float appears stuck or it is not functioning properly, clear it of any visible debris.
- Make sure the float is set at the proper height for your toilet.
