Backpressure definition
Backpressure means a pressure (caused by a pump, elevated tank or piping, boiler, or other means) on the consumer's side of the service connection that is greater than the pressure provided by the public water system and which may cause backflow.
Backpressure means any elevation of pressure in the downstream piping system (caused by pump, elevated tank or piping, steam and/or air pressure) above the water supply pressure at the point which would cause, or tend to cause, a reversal of the normal direction of flow.
Backpressure means any elevation of pressure in the downstream piping system (by pump, elevation of piping, or steam and/or air pressure) above the supply pressure at the point of consideration, which would cause, or tend to cause, a reversal of the normal
Examples of Backpressure in a sentence

More Definitions of Backpressure
Backpressure means the flow of water or other liquids, mixtures or substances under pressure into the distribution pipes of the Public Potable Water Supply System from any source or sources other than the intended source.
Backpressure means an elevation of pressure downstream of the distribution system that would cause, or tend to cause, water to flow opposite of its intended direction.
Backpressure means backflow caused by connection of a public water system to a non-potable system which is operating under a higher pressure than the public water system. The cause of the higher pressure includes, but is not limited to, a pump, boiler, elevation difference, or air or steam pressure.
Backpressure means a pressure, higher than the supply pressure, caused by a pump, elevated tank, boiler, air or steam pressure, or any other means, which may cause backflow.
Backpressure means any increase of pressure in the downstream piping system (by pump, elevation of piping, or steam and/or air pressure) above the supply pressure at the point where backflow could occur.
Backpressure means a condition in which the owner’s system pressure is greater than the supplier’s system pressure.
Backpressure means any elevation of pressure in the downstream piping system (caused by pump, elevated tank or piping, steam
