Location of the Main Stopcock

A stopcock controls the flow of water from a main supply water line into a residence or other type of building. Knowledge of the location of  this valve becomes vital in the event of a break occurring in a water  pipe located inside a residence. Water flowing from a split or cracked  water pipe can cause flooding within the property.

To protect your  belongings and to save time in the event of a plumbing catastrophe,  learn and remember the location of this important valve.

The stockcock can be hard to find, but a good place to look is under the kitchen sink, other locations can be in a basment.  If the cold water stops at the main kitchen cold tap, you can be almost sure you have located the correct valve.
