A ballcock is a ball float on the end of a lever in the water closet of a toilet. As the level of water in the closet rises, so does the floating ballcock. When the water level is high enough, the lever operates a sliding valve and the water coming into the closet is shut off.
When you start to unscrew a ballcock, you are essentially loosening the connection between the ballcock and the water supply line. This allows you to either remove the ballcock for maintenance or replacement, or to adjust the float level to control the water level in the tank.
If you open the lid on your toilet you should see the ballcock. It is normally on the left side and has the float, that looks like a ball, attached to it. It is used to fill the water in the bowl and set the height of the water.

Just replace the ballcock valve..
A surge in water pressure can cause this. Also, a defective ballcock would pop off under these conditions. Replace the ballcock and consider installing a pressure reducing valve (PRV) on the incoming water line.
Turn off the water and drain the tank. Sop up excess as needed. Remove old ballcock and install new one. Connect chain and verify slack, but not too much slack, and that the chain will not catch an anything. Turn on water and let tank fill. Flush several times and verify correct operation. Double check chain. Sometimes, the ballcock seat is bad. You can replace it, but that is usually difficult and occasionally gets out of hand. They make a ballcock with seat replacement. The seat sits on top of the old seat using some kind of putty. Ususally, you remove old ballcock, clean and dry seat, apply putty bead to new seat, and press on, following any specific directions in the kit. In all cases, you need to check the minimum drain level. There is a cup on the back of the ballcock that lets you adjust how far down the water goes before the ballcock closes. This can save water. Set it to where the flush is correct for your application.
Your ballcock is comming on -- replace tank ball or sometimes you have to change out flush valve -- but change tank ball first and see if that will do it You hardly ever have to change flush valve -- Your ballcock is what lets water come into your tank
To allow toilets to fill from the water line without overflowing.
No. The instructions for replacing the ballcock valve should be printed on the package for the new valve. You can also discuss it with an employee at a good hardware or home improvement store who should be able to explain and maybe even demonstrate the procedure for you.
Thomas Crapper invented the ballcock which was the first type of toilet thank you very much.
Turn off the valve & tie up the ballcock...
