Back pressure means pressure that is higher than the ambient pressure in the water distribution system of the Corporation;
Back pressure means a form of backflow caused when the pressure of the water users' system is greater than that of the water supply system. This could be caused by a pump, elevated tank, elevated piping, boiler, pressurized process, pressurized irrigation system, air pressure or any other cause of pressure.
Back pressure means any elevation of pressure in the downstream piping system (by pump, elevation or piping, or stream 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 direction of flow through the backflow prevention assembly.
