Other Applications For RPZ's
Although these pages deal mostly
with backflow prevention on irrigation systems,
backflow protection covers many different connections to a public water system.
If you are plumbing a new construction facility and connecting to a public water
system, check the list below and see if backflow protection may be necessary.
This
list is provided as a guide to cross-connection control administrators. By no
means does this list
include all possible High
Hazard facilities. The list is provided to aid the cross-connection
control
surveyor or inspector in making a
determination of the types of establishments which under normal
circumstances would tentatively
meet the definition of a High Hazard facility. The AHD always
recommends an inspection of an
existing facility to confirm the hazard level before requiring a
backflow
preventer. Under special
circumstances, specific facilities covered by the categories listed below might
qualify as Medium or Low
Hazard facilities. For new
construction, the facilities listed below
should have a RP type backflow
prevention assembly designed into the water service line.
