Atmospheric |Vacuum |Breaker |(AVB) |- |✔✔💯Backflow |prevention |device |that |allows |air |into |the |
piping |system, |with |the |use |of |a |float |that |moves |up |and |down, |to |prevent |backsiphonage. |
Cannot |be |under |constant |pressure |for |more |than |12 |hours |in |one |24 |hour |window.
A |minimum |of |6" |higher |than |all |down |stream |piping.
A |separate |AVB |must |be |installed |on |the |discharge |side |of |each |control |valve, |between |the |valve |and
|all |emission |devices.
Automatic |control |valve |- |✔✔💯An |electrical |or |hydraulic |remote |control |valve |in |a |sprinkler |system |
which |is |activated |by |an |automatic |controller
, Backflow |- |✔✔💯An |unwanted |reversal |of |the |flow |of |water |in |a |piping |system |which |can |potentially
|allow |non-potable |water |to |pollute |or |contaminate |the |potable |water |supply.
Backpressure |- |✔✔💯Any |condition |that |could |create |pressure |in |the |discharge |side |of |the |piping |
system |that |is |greater |than |that |of |the |supply |side |of |the |system.
Backsiphonage |- |✔✔💯A |form |of |backflow |due |to |negative |or |sub-atmospheric |pressure |within |water
|system.
Backflow |prevention |methods |- |✔✔💯Any |approved |device |which |prevents |an |undesirable |reversal |
of |flow |of |water |by |the |introduction |of |air, |check |valves, |or |a |combination |of |both.
Backflow |prevention |devices |- |✔✔💯Air |Gap
Atmospheric |Vacuum |Breaker |(AVB)
Pressure |Vacuum |Breaker |(PVB) |
