The leakage conduit has a sealed connection with a casing sealed to the main and enclosing a corporation stop to which the service conduit is connected. The leakage conduit is sealed to the service conduit within the building and adjacent the meter and includes an outlet extending outwardly through the building wall above the ground so that leakage within the corporation casing or a leak in the service conduit may be quickly detected.
