FAQs

What is the primary use of this backflow preventer?

This backflow preventer is primarily used in fire protection systems to prevent the reverse flow of polluted water into the potable water supply and to detect system leakage or unauthorized water use through its metered bypass.

What does "Z-pattern lay length" mean for this product?

The Z-pattern lay length indicates a specific, longer dimension for the valve assembly, which makes it a direct "drop-in" replacement for competitor backflow preventers with similar Z-pattern configurations.

What material is the body made from, and what is "ArmorTek coating"?

The body is constructed from Ductile Iron Grade 65-45-12. ArmorTek coating is a patented 3-part advanced epoxy system applied to both internal and external surfaces to protect against microbial induced (MIC) and exposed metal substrate corrosion.

What is the maximum operating pressure for this assembly?

The maximum working pressure for this 6-inch Double Check Detector Backflow Preventer Assembly is 175 psi (12.1 bar).

Are special tools required for servicing this backflow preventer?

No, the design of this assembly, specifically its main valve and bypass, does not require special tools for servicing, simplifying maintenance procedures.
