the flow of water or other liquids, mixtures or substances into the distributing pipes of a potable supply of water from any source other than from its intended source.

A

BACKFLOW

17
Q

the flowing back of used, contaminated or polluted water from a plumbing fixture or vessel into a water supply due to a negative pressure in such pipe.

A

BACK-SIPHONAGE

18
Q

an unobstructed vertical distance through the free atmosphere between the lowest opening from any pipe or faucet conveying potable water to the flood level rim of any tank, vat or fixture.

A

AIRGAP, WATER DISTRIBUTION

Q

has an air inlet valve that closes when the water flows in the normal direction. But, as water ceases to flow the air inlet valve opens, thus interrupting the possible backsiphonage effect.

DOUBLE CHECK VALVE BACKFLOW PREVENTION ASSEMBLY

21
Q

has an air inlet valve which is designed to open when the internal pressure is 6.9 kPa (1 psi) above atmospheric pressure so that non-potable will not be siphoned back into the potable water system. It includes a check valve that is designed to close with the aid of a spring when flow stops.

A

Principle No. 2

24
Q

Inadequate Water Pressure – whenever the water pressure in the main or other source of supply will not provide a water pressure of at least ___ after allowing friction and other pressure losses, a hydro pneumatic pressure tank or an elevated tank and booster pump will provide 103 kPa pressure.

A

103 kPa (15 psi)

25
Q

Excessive Water Pressure – when the local water pressure is in excess of ___, an approved-type pressure regulator preceded by an adequate sized strainer shall be installed to reduce pressure on the building side of the regulator to the required supply pressure.

Q

is a pressure surge or wave resulting when a fluid in motion is forced to stop or change direction suddenly (momentum change).

commonly occurs when a valve is closed suddenly at an end of a pipeline system and a pressure wave propagates in the pipe. It may be known as hydraulic shock. This pressure wave can cause major problems from noise and vibration to pipe collapse.
