Every homeowner should locate their main water shut-off valve and know how to use it.
There are two types of main water valves: the gate valve and the ball valve.
The gate valve is recognized by its round handle that must be turned a number of times to open or close the valve.
The ball valve is recognized by its single handle that needs to be turned ¼ turn or 90 degrees, to turn the water on or off.
City Wide Plumbing can tell you about the condition of the main water valve in your home and replace it if necessary.
