PVC (Polyvinyl Chloride): A rigid white or cream-colored plastic pipe used in non-pressure systems, such as drainage, waste, and vent systems. Pressure Tubing: Tubing used to conduct fluids under pressure or at elevated temperatures or both, and produced to stricter tolerances than pipe. Pressure Tank: Device used to pump water from a well. As a result, temperature remains constant, though the outlet pressure may drop. Pressure Balance Valve: Shower mixing valve that automatically maintains balance between incoming hot and cold water supplies by immediately regulating fluctuations in pressure. The maximum head is determined by the horsepower available and the casing strength. the capacity determined by the pump speed. Gear, sliding vane, progressive cavity, lobe etc. Positive Displacement Pump: Called a PD pump. Port: An opening in a burner head through which gas or an air-gas mixture is discharged for ignition. When a lavatory lift rod or bath overflow plate lever is lifted, the pop-up drain closes so the lavatory or tub retains water. Pop-Up Drain: Type of drain assembly for lavatory and bath.

Pitch: Downward slope of a drain pipe in the direction of the water flow. Substance applied to threaded fittings to create a watertight seal.
Pipe Dope: Slang for pipe-joint compound. Below 7 denotes acidity above 7 denotes alkalinity. PH: Potential Hydrogen, the hydrogen ion concentration of water to denote acidity or alkalinity, measured on a scale of 0 to 14. Peak Hour Demand: Time when the largest demand for hot water is needed. PB (Polybutylene): Flexible plastic tubing used in water supply systems where allowed by code. Packing Nut: Nut that holds the stem of a faucet in position & holds the packing material. Packing: Fibrous material that is used on faucets to prevent leaks. Outlet Sewer: Pipe section in a septic system which runs between the septic tank and the drainage field. Oakum: Loosely woven hemp rope that has been treated with oil or other waterproofing agent it is used to caulk joints in a bell and spigot pipe and fittings. O-Ring: Round rubber washer used to create a watertight seal, chiefly around valve stems. O.D.: Abbreviation for Outside Diameter. A variation, a neoprene sleeve with two adjustable steel bands, is used for connecting dissimilar materials, as when connecting new plastic pipe to an existing cast-iron drainpipe. No-Hub Connector: A connector for no-hub iron pipe consisting of a rubber sleeve and a stainless steel band secured by hose clamps. Nipple: A short length of pipe installed between couplings or other fittings. Multi-Stage Pump: A pump that has more than one impeller. Mechanicals: The wiring, plumbing and heating and cooling systems in a building also the components with moving parts such as furnaces, plumbing fixtures, etc. Manifold: A fitting that connects a number of branches to the main serves as a distribution point. Malleable Fittings: Fittings made of metal which is soft and pliable. Male Threads: Threads on the outside of pipes and fittings. In the case of drains, known as the Main Vent. Main: The primary artery of supply of the water supply or drain system in which all the branches connect. Lock Nut: Nut fitted into a piece of pipe and screwed onto another pipe to join the two pieces. Leader: Pipe carrying rainwater to the ground or sewer. Leach Field: Porous soil area, through which septic tank leach lines run, emptying the treated waste.
