Water refilling a toilet tank is an expected sound.
But how long should this sound continue?
The sound is brief and ends when the water fills the tank.

The overflow pipe is a vertical plastic tube located at the center of the toilet tank.
If readjusting the refill tube does not work,replace the toilet flapperwith atoilet flush valve repair kit.

This toilethammering soundis sometimes heard in other fixtures and appliances, especially washers.
In toilets, the sound occurs after the toilet tank has finished filling up.
Angle the cylinder toward the toilet.
Not only does this improve the appearance, but it also protects the cylinder from accidentally breaking off.
It can sometimes sound like a foghorn or that it’s humming.
The sound is brief, but it happens nearly every time you flush the toilet.
Older plastic valve handles are particularly brittle.
If that fix does not stop the toilet from moaning, replace the toilet’s water supply valve.
