Identifying the Cause of a Running Toilet

Before we dive into how to fix a running toilet, you should know that the flapper valve, water level in the tank, and float ball are the usual culprits. Here’s what you can do to identify what’s causing your running toilet:

Checking the Flapper Valve

The flapper valve is one of the first things you should examine when attempting to fix a running toilet. The flapper valve, a rubber seal, closes the gap between the toilet bowl and the tank. It is opened by the flush handle, allowing water to flush the toilet by flowing from the tank into the bowl. Water will continue to flow from the tank into the bowl if the flapper valve is not sealing properly, which will result in the toilet running.

How to fix a running toilet with this issue? Start by flushing the toilet and allowing the tank to refill before checking the flapper valve. When the tank is full, check the flapper valve to make sure it is sealing correctly. The flapper valve may be jammed or damaged if it is not sealing properly. To test whether the flapper valve will release and seal properly, try to lightly wiggle it. You might need to replace the flapper valve if this doesn’t work.

If the flapper valve seems to be working just fine, move on and check the other parts below.

Checking the Water Level in the Tank

For the toilet to work effectively, the water level in the tank needs to be at a specific level. The toilet won’t flush correctly if the water level is too low and it may start to run if the water level is too high.

Start by flushing the toilet and allowing the tank to fill up before checking the water level. Once the tank is filled, check the water level inside by looking at the line which should be just below the overflow pipe. You might need to bend the float arm or adjust the fill valve to lower the water level if it is too high and call in a professional plumber if the water level is too low.

Checking the Float Ball

If the first two usual reasons for a running toilet are working as they should check the float ball. The float ball is hollow and rises and falls in response to the water level as well as controls the fill valve. If there’s an issue with the float ball, here’s how to fix a running toilet:

Start by flushing the toilet and letting the tank fill up before checking the float ball. Check to check if the float ball is rising and falling gently with the water level after the tank is full. The toilet may be running if the float ball is not moving freely or is trapped in a position that is too high or low. If you are unable to adjust it, you will need to replace it
