The Flapper

Sometimes the water comes out or trickles through the bowl for leakage around flapper. You can test it simply by turning off the water supply at the shutoff valve. If you notice that the water in the tank is dropping noticeably, understand that the problem might be in the flapper chain.

If the chain of the flapper is too tight, these types of water dropping happen. All you have to do is adjust it slightly to settles back in its place.

Are you still hearing water leak into the bowl? If that is the case, the second possible source is leakage around the flapper.

In this case, you have to replace the flapper. Replacing a flapper is not hard. The first step is to drain the tank and pull it loose. Adjust a matching flapper that suits onto the hinges of the overflow tube. Sometimes the rubber label needs to be repaired.

The Inlet Valve

If you’ve already tried the above steps and it doesn't work, take a look inside the tank. If the water level rises above the overflow tube the problem might be with the inlet or float valve.

To know what the problem is you have to determine the technology behind the valve system. Know that the rising water instruct inlet valve when to shut "Off" and "On". If this mechanism got interrupted somehow, it keeps spilling the rising water through the overflow tube and into the bowl.

To examine the inlet valve, you have to flush the toilet and check whether the water flow is stopping of not while holding the floating rod.

If it doesn't stop, you have to adjust the float valve moving down slightly, ensuring it’s not touching or hampered by anything else.

You can also try to fix it by turning screws on top of the valve. If you still face the problem, you have to replace it.

If the water stops flowing while holding the floating rod, the inlet valve is fine and the problem resulted in by the float.

Float Valve

Now check whether the float valve is shutting off properly or not. Pull up the float to see if the water running stops. If it stops adjust the level of the float in the inlet valve.

You will find a screw at the top of the ballcock. It will allow you to adjust the level of the float. You can reduce or raise the level of the water in the tank by this adjustment.

After the adjustment, if you face the same problem running, check the float if it has any hole and lies too low in the water. The hole doesn't allow the float to raise enough to the inlet valve and caused the problem of dripping water.

In these cases, you have to fix your tank by replacing the float but don't take the stress. It's easy to replace and also inexpensive.

Flush Valve and Seal

Sometimes the seal and the flush valve between the tank and bowl becomes old and cracked. So, you know what to do, replace it and solve the problem.
