FAQs
What is the primary purpose of this 8 inch Double Check Detector Assembly?
Its primary purpose is to prevent the reverse flow of non-potable fire protection system substances, such as glycerin wetting agents or stagnant water, from entering the potable water supply line. It is mandatory for water authority containment requirements.
What is ArmorTek® coating technology and why is it important?
ArmorTek® is a patented three-part advanced epoxy system that coats the iron components of the backflow preventer. It is engineered to reduce microbial-induced corrosion (MIC) and protect exposed metal substrate, enhancing the assembly's durability and lifespan.
Does this backflow preventer help detect water leaks?
Yes, this assembly not only detects leaks, with an emphasis on unaccountable water, but also incorporates a gallons per minute meter. This meter allows the water utility to detect underground leaks and identify unauthorized water use, helping to locate illegal taps.
What are the key certifications and approvals for this 709DCDA assembly?
This assembly is UL Listed, UL Classified, and FM Approved, specifically for its resilient seated OSY shutoff valves and test cocks. It also meets the basic requirements of ASSE 1048 and AWWA Std. C510 for Double Check Valves.
What type of shutoff valves are included with this assembly?
The assembly is standardly equipped with resilient seated OSY (Outside Stem and Yoke) shutoff valves. These valves are also UL Classified and FM Approved.
