If your toilet does not stop running after flushing, there are a number of potential causes. It is important to find the root of the issue and make necessary repairs as soon as possible, as you are likely losing hundreds of gallons of water every day.
Common Reasons Why Your Toilet Keeps Running, Include:
- The flush handle and tank ball (or flapper) aren’t connected properly
- The flapper valve or tank ball are getting stuck, due to damage or mineral buildup
- The float ball is damaged or not adjusted correctly
To figure out what might be going wrong, take a look inside the tank at the various parts.
Flush Valve Issues
Does the toilet stop running after you wiggle the flush lever a bit? The problem probably lies with the connection between the flush handle and the tank ball or flapper, which is the mechanism at the bottom of the tank that blocks the tank water from draining into the toilet bowl. These parts are typically connected by a chain, which may be catching on something.
Tank Ball Or Flapper Valve Issues
Another cause of a running toilet may be a sticky flapper or tank ball, which is supposed to fall back into the drain after the toilet bowl refills. If it is not properly falling, the flapper itself may be damaged or contain a buildup of mineral deposits or warping. Alternatively, the issue may be with the hinge of the flapper, in which case the part may need to be replaced.
Float Ball Issues
The float ball, or float, is the balloon-like part of the toilet tank that rises along with the water as the pump refills the tank after flushing. When it reaches a certain level, the pump stops. If the float is damaged, or improperly adjusted, it may be sending the wrong signals to the pump, which in turn, doesn’t know when to stop pumping.
