Abstract:
Selecting a dimension representing the distance between a residential gas hookup, downwardly through an intended subterranean trench to a gas main typically located along a public right of way, such as a street, and selecting a plastic pipe having a predetermined length at least equal to such dimension. Then, fabricating at a manufacturing site remote from the intended site of installation, a kit including a metallic riser having an upper end formed with a coupling screw thread and a lower end. Inserting one extremity of the plastic pipe through the riser to leave an excess length projecting from such lower end, forming a joint between the plastic pipe and such upper end, coiling such excess length into a coil and securing the assembly in a package to form the kit. A selected number of the kits may then be stored in their packaged form for subsequent shipment to the installation site to be installed and connected to make a hookup between the hookup location at respective residences and such main gas line.
