The District encourages its customers to know where the shut-off valve is located to their home and to periodically turn the valve on and off to be sure it is in good working condition.
The older style shut-off valve in most older homes is shut off with the angle rod seen above ground at an L shape and typically located below the outside faucet at the foundation street side of the house. Care should be taken not to use extreme force when trying to operate the older angle rod type. Over the years valves may not turn easily and could be damaged. These types of shut-off valves are 1/4 turn Ball Valves. To shut off, you must turn the valve clockwise a 1/4 turn (some of these valves do not have a stop and will continue to turn all the way around). Customers should make sure the valve is turned back to the full "on" position after locating and turning the valve. If the valve is only partially on it may continue to drain water and leak.
Newer home installations are typically located in the garage area. The valve would be turned clockwise when closed. Care should be taken when turning the valve off and on, not to use extreme force as damage may occur to the shutoff gate valve.
