A tool used to drive the lead firmly into a lead and oakum joint when working with hub-and-spigot cast-iron pipe and fitting.
A fitting used to connect the water closet to the closet bend.
A joint formed using a neoprene gasket inserted into the bell end of a hub-and-spigot pipe. The pressure applied between the two joined pipes forces the gasket to compress and fills in any air gaps in the joint.
A fitting used to connect two lengths of no-hub cast-iron pipe.
A type of cast iron in which magnesium is added to the molten gray iron to reduce brittleness.
The length of a pipe that fits into the fitting or other joint when assembling a pipe run. The measurement must be figured into the calculation before cutting a piece of pipe for joining.
Fiber rope that is clamped around the pipe using a spring clamp to keep the hot, molten lead in the hub when making a lead and oakum joint. Also called running rope.
A spoon-like tool used to dip the molten lead from the lead pot and pour it into the joint.
Lead and Oakum Joint
A joint for hub-and-spigot cast-iron pipe that involves pouring molten lead over oakum fiber to form a water-tight seal between the two pieces of pipe, then caulking the joint after the lead has cooled.
A vessel used to hold molten lead. It is placed on the head of the propane melting furnace during the melting process.
The principal pipe artery to which branches may be connected.
A caulking material of old hemp rope or jute fibers that have been treated with tar or a tar derivative.
A tool with a board, thick blade used to pack oakum into a joint with a hammer.
A tool with a diamond-shaped flat point used to remove the lead and oakum from a joint.
Powder-Actuated Fastening Tool
A tool that uses a 0.22-caliber shell to drive nails or fasteners into the framework of a structure. It may be used only by certified workers.
Propane Melting Furnace
A device used to melt lead. It burns liquefied petroleum (LP) gas.
Rotary Hammer Drill
A drill with a pounding action that lets you drill into concrete, brick, or tile. It rotates and hammers at the same time and drills much faster than regular drills.
A lightweight kind of cast-iron pipe. Service refers to the pipes, thickness which can vary.
Measurement of the fall of a length of pipe from level. The change in level is expressed in degree of an angle. Also referred to as percent of grade.
Soil Pipe Cutter
A heavy-duty tool used for cutting cast-iron pipe. Soil pipe cutters can be of the snap or ratchet type.
A tool used to clamp the running rope around the pipe next to the hub when making lead and oakum joints.
A support that keeps lengths of cast-iron pipe from swaying when they are suspended.
A fitting with a radius of the curve greater than 90 degrees. Used for a smooth change of direction.
A wrench with a gauge or other means to indicate the amount of rotating force applied to a fastener, such as a nut, as it is turned.
A tool used to pack the oakum fiber into the joint when making lead and oakum joints to connect hub-and-spigot cast-iron pipes.
