FAQs

What is the primary use of this 10 inch backflow preventer?

This assembly is primarily used on potable drinking water systems to prevent the backflow of non-health hazard pollutants due to backsiphonage or backpressure conditions, especially at cross-connections or service line entrances.

What does "Lead Free" mean for this product?

"Lead Free" means that the wetted surface of this product, which contacts consumable water, contains less than 0.25% of lead by weight, complying with low lead installation requirements.

What is ArmorTek coating and what are its benefits?

ArmorTek is a patented three-part advanced epoxy coating system applied to the iron components of the backflow preventer. It is engineered to reduce microbial-induced corrosion (MIC) and protect exposed metal substrate.

What is the maximum operating pressure for this backflow preventer?

The maximum working pressure for this 10 inch double check valve backflow preventer assembly is 175 psi (12.1 bar).

Does this assembly include shutoff valves?

No, this specific model (LG) is supplied "Less Shutoff Valves." Shutoff valves would need to be procured separately if required for the installation.
