Stop taps are often called stopcocks, most people will know them as stopcocks. A stop tap is often found on the rising water main of a property and is used to isolate the water supply. Normally there are two stop taps, one on the boundary of the property, which is the water companies responsibility and one on the inside of the property, which is the owners responsibility.
A stop tap is connected to the supply pipe by a compression nut and olive at each side of the tap. You can see from the picture Below that there is a directional arrow on the tap. The arrow must point in the direction of the flow of water.
