Abstract
A service connection between a water main and a meter within a building has a service conduit within a leakage conduit. 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. In the event of a leak, the service conduit may be removed and replaced through the leakage conduit with excavation limited to exposing the corporation casing and the end of the leakage conduit connected thereto. A snake provided with a flexible wedge that includes connections with an existing service conduit and a leakage conduit to be installed enables the former to be withdrawn and the latter simultaneously to be pulled through the ground to effect its installation. The flexible wedge may be double ended with a cable connected to each end.
