FLOMATIC SPECIFICATIONS:
Reduced Pressure Principle backflow preventer shall
protect against backflow by either backpressure or
backsiphonage from a cross-connection between
potable water systems and substances that are nonhealth and health hazards.
The device shall be constructed from unleaded bronze
with less than 0.05% lead content (Federalloy I-836 or
approved equal). It shall consist of two (2)
mechanically independent, spring loaded, center stem
guided check valves. It shall also have a hydraulically
dependent differential pressure relief valve with the
sensing passage set in an integral cast unleaded
bronze body, with a single access cover. The
assembly shall have four (4) vertical test cocks and
two shut off valves which are quarter-turn, full-port,
resilient seated and ball type which are constructed
with low lead material, less than 0.25% lead content
(ASTM C90500) or approved equal.
The relief valve shall have removable stainless steel
seat ring. The check valves shall be held into place by
stainless steel clips and the check valve assemblies
shall be non-interchangeable with silicone discs.

TYPICAL INSTALLATION
Model RPZE Reduced Pressure Backflow Preventers
should be installed with adequate clearance and easy
accessibility for testing and maintenance and must be
protected from freezing. Local codes shall govern
installation requirements. Unless otherwise specified,
the assembly shall be mounted at a minimum
clearance of 12” (305mm) between port and floor or
grade. The assembly shall have a maximum of 30”
(762mm) above adequate drains with sufficient side
clearance for testing and maintenance. The installation
shall be made so that no part of the unit can be
submerged. Thermal water expansion can cause
excessive pressure. Excessive pressure situations
