TYPICAL INSTALLATION

Model RPZE II 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
should be eliminated to avoid possible damage to the
system and assembly.

WARRANTY: Flomatic valves are guaranteed against defects of materials or workmanship when used for the

services recommended. If in any recommended service, a defect develops due to material or workmanship, and the
device is returned, freight prepaid, to Flomatic Corporation within 12 months from the date of purchase, it will be
repaired or replaced free of charge. Flomatic Corporations’ liability shall be limited to our agreement to repair or
replace the valve only.
