FAQs

What is the primary purpose of the FEBCO MasterSeries LF876WZ Double Check Detector Assembly?

Its primary purpose is to protect potable drinking water and fire sprinkler systems from pollution caused by backpressure or backsiphonage of non-health hazard water, while also detecting potential leaks or unauthorized water usage via its metered bypass.

What does "Lead Free" mean for this product?

"Lead Free" signifies that the wetted surfaces of this product, which come into contact with consumable water, contain less than 0.25% lead by weight, ensuring compliance with health standards.

Can this backflow preventer be used to replace other brands?

Yes, this FEBCO MasterSeries LF876WZ assembly is specifically designed with a longer Z-Pattern lay-length to serve as a direct drop-in replacement for competitor's Z-pattern valves.

What is the significance of the ArmorTek coating?

The ArmorTek coating is a patented three-part advanced epoxy system applied to the ductile iron components to reduce microbial-induced corrosion (MIC) and protect the exposed metal substrate from degradation, enhancing the assembly's longevity.

Does this model include shutoff valves?

No, the 8 LF876WZ-LG-GPM model is configured "Less Shutoff Valves" (LG). Shutoff valves would need to be sourced separately if required for the installation.
