The leak detection system includes a leak detector including an enclosure in fluid flow communication with the portion of the conduit downstream from the valve, a member responsive to the fluid condition within the enclosure and signal means responsive to the fluid condition responsive member for indicating the existence of a predetermined fluid condition.
A valve seating means which is pressure activated to forceably seat the valve also is provided.
A leak detecting method is disclosed which includes the steps of activating the pump, opening the dispenser and dispensing a fluid, closing the dispenser, closing the valve to isolate the pump from the dispenser, sensing a flow of fluid in the conduit portion between the valve and dispenser, and energizing signal means if the fluid flow is greater than a predetermined amount.
