There is an easy fix to this common issue. And best of all, it takes only a few household tools and virtually no time at all.

Before we get started, let’s learn a little about the parts of your toilet so you know where to get started…

The Fill Valve

The fill valve is located inside the tank of the toilet on the left side. It is connected to a water line and is responsible for filling your toilet once you have flushed.

The Float

Attached to the fill valve you will find a float. Once you flush the toilet, the float will sink with the water level. As the water returns to the tank, the float will be used to gauge the water level and stop the tank from overfilling.

The Flush Valve

The flush valve is in the center of the tank. It is covered by a flapper, which opens when you flush the toilet. When the flapper is open, the water can leave the tank and go into the bowl to do its job. Once the water has emptied from the tank, the flapper will close and the tank will begin to fill with water.

There are a few common culprits for a running toilet, and most of them are an easy fix.

1. Toilet Flapper – Needs To Be Inspected

The seal between the flapper and the flush valve prevents water from leaking out of the tank. When the flapper is bad, water will leak from the tank to the bowl. You will know the flapper needs to be replaced if you inspect it and see irregular notches or bumps. The edges of the flapper should be smooth and fit snug within the flush valve. A properly sealed flush valve causes the float to go down and tell the tank it needs to refill. When the seal is broken, the water will continuously leak and the tank will keep trying to refill. The fix to this is easy. Turn off the water to your toilet by turning the shutoff valve clockwise. Flush the toilet to empty the tank. Then, remove the flapper and take it with you to the hardware store. Be sure to note what brand your toilet is. Buy a replacement flapper, put it back on, and you’re good to go. Don’t forget to turn the water back on.

2. Toilet Flapper Chain – Is Too Long

If the flapper is in good condition, the next thing you should do is check the chain. The chain connects your toilet handle to the flapper. When you flush, the pull from the handle causes the flapper to open and release the water into the bowl. If the chain is too long, it can become tangled and get stuck between the flapper and the valve. This breaks the seal between the flapper and the valve and makes the tank leak. To fix this problem you can reduce the slack on the chain where it connects to the toilet handle. Simply move the clip that connects the chain to the handle further down the chain. Snip off any extra chain with wire snips.

3. Toilet Fill Valve – Check Your Water Level

If you have checked the flapper and the chain and you still hear the water running, you may have a problem with the water level inside your tank. The water in your tank should be about a ½ inch to 1 inch below the overflow pipe in your tank. If it is too high, you will likely hear a constant running sound. To adjust your water level, you will need to adjust the height of your float. If you look at your float, you will see a screw that connects the float to the fill valve. Simple turn the screw counterclockwise, just enough to lower the float. If your float has a metal arm that connects it to the fill valve, you can bend the arm to lower the level of the float.

    I did everything like you said, but I still Get a slight water leak in the front inside bowl.
    When I shut off the water supply line then it stops leaking completely.
    When I turn the water supply line back on it starts leak again.
    Am I missing something. I have the new assemblies.
