From time to time, the toilet brands will keep running for various reasons. It is a common plumbing problem that will raise the water bill if it is not fixed in a timely manner. Luckily, a running toilet can be easily repaired. There are certain areas to check to find out why the toilet is running.
Check Water Valve
If the water does not come up to the water line, check the water valve to see if it is turned on all the way. If it is not, turn the valve all the way on to fill the tank up to the water line. Next, flush the toilet. If the water fills to the water line, the problem will be solved.
Check Overflow Tube
Remove the lid and flush the toilet. If water is seen going into the overflow when the tank is full, it means that the valve is not shutting off as normal. When this happens, the overflow tube will need to be replaced. The overflow tube can be easily replaced, see more on this Facebook page.
Check Flapper Chain
If the overflow is not the problem, look inside the toilet tank to see if it is the flapper chain that is causing the toilet to run. If the chain is too short or too long, it could be why the toilet is running. A short chain will prevent the flapper from going all the way down to seal the opening of the tank. If the flapper chain is too long, it will most likely get caught under the flapper and will keep it from sealing. To fix the problem, a simple adjustment will be needed.
Check Flapper Seal
Over time, flappers get old and stiff, which will prevent them from sealing properly. Adding a few drops of food coloring to tank is a great way to check to see if there is a leak. Wait about an hour, and be sure not to flush the toilet. If food coloring is seen in the bowl, the flapper is leaking and will need to be repaired.
These are common areas to check when the toilet continues to run. Generally, the trouble centers around the water valve, overflow tube or with the flapper chain or flapper seal. Either one of these problem areas can be easily repaired or replaced.
