This stopcock looks like a tap under the sink
Stopcock under the sink
The stopcock is a valve for turning off and on the cold water system in your home. When you turn the stopcock in a clockwise direction the water supply will be shut off. You can turn the water supply back on by turning the stopcock in an anti-clockwise direction.
Stopcocks are usually found in your kitchen, below the sink unit.  However in some houses the stopcock is found in a front or back hall or in a larder unit beside the sink unit.
It is important that you know where the stopcock is and that you check that your stopcock is working.

How do I check my stopcock?
