There should be a screw at the valve end that can be screwed in and out, but it is usually so corroded that you can't. Most of the time, you just bend the rod the ball is on to adjust the water level.

When you start unscrew a ballcock what happens?

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.


Where is a ballcock used?

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.

Why would a first floor toilet gurgle when a second floor toilet is flushed?

The water in the lower toilet is probably being siphoned out of the tank by the negative pressure caused by flushing the upper toilet. This CAN happen if the water level in the tank of the lower toilet is over the top of the ballcock. If this is the case, the tank water is being siphoned into your drinking water! Replace the ballcock with a Fluidmaster right away. If you have a small white fill valve that sits in the bottom of the tank, get rid of it. These are illegal and WILL siphon under these conditions. If the lower toilet runs AFTER the fill cycle of the upper toilet, it may be that the ballcock seals at a lower pressure, and the pressure spike when the upper toilet shuts off causes it to run a bit until the added water closes the valve a little tighter.
