Backflow Prevention Assembly Tester
Training
0.433 - ✅✅-For every one foot of water you generate how much PSI?
1 PSID - ✅✅-Minimum standards for passing check valve
100 psi - ✅✅-Maximumun pressure delivered to customers
14.7 PSI - ✅✅-Atmospheric Pressure at sea level
2.31 feet - ✅✅-27 3/4 inches
2.31 ft - ✅✅-1.0 PSIG
20 psi - ✅✅-Minimum system pressure
27 3/4 - ✅✅-2.31 feet of head
3 methods for testing check valves - ✅✅-1. Seating with backpressure
2. Seating with flow
3. Differential (PSID)
33.9 feet -✅✅ -Only pertains to suction/vacuum. Absolute furthest water can
be pulled up a column under a complete and total vacuum/siphonage
35 psi - ✅✅-Minimum static pressure
4 preliminary steps to testing - ✅✅-Notify, identify, inspect, or observe.
4,3,2,1 - ✅✅-Flush test cocks in this sequence
60 psi - ✅✅-Average working pressure
62.4 - ✅✅-(7.48 gal/ft3)(8.34lbs/gal)
7.48 gallons - ✅✅-1 ft3 of water
8.34 lbs - ✅✅-1 gallon of water
, ✅✅
A valve designed to open in the direction of normal flow and close with the
reversal of flow. - -Check valve
Actual Cross Connection - ✅✅-Any arrangement of pipes, fittings, that
connects a potable water supply directly to a non-potable source at all times.
Air Gap - ✅✅ -A physical seperation between the free flowing discharge end
of a potable water supply pipeline and the highest flood level of an open or
non-pressure receiving vessel.
Air Gap - ✅✅ -In plumbing, the unobstructed vertical distance through the
free atmosphere between the lowest opening from any pipe or outlet supplying
water to a tank, plumbing fixture, or other container, and the overflow rim of
that container
Air Gap - ✅✅ -Requires a minimum vertical air space 2 pipe diameters
above the flood rim.
Requires a minimum 1 in. Distance.
Air Gap - ✅✅ -Testing requirements: it does not require "testing" as the other
devices. But it should be inspected to make sure it has not been nullified with
objects such as hoses or pipes.
✅✅-2x Supply line diameter but not less than 1".
Airgap -
Approved airgap seperation - ✅✅-Backsiphonage, backpressure,
containment, and pollutant
Area - ✅✅-Measures in square inches (in2)
Area - ✅✅-Measures the surface of an object
Area - ✅✅-Tells how big something is
Area - ✅✅-The extent of a planar region or the surface of a solid measured
in square units
