Trends in Backflow Preventer Valve Selection and Location - New Guide

    NASHVILLE, TN, September 21, 2016 /24-7PressRelease/ -- It's been happening under our noses, or actually under our feet, but hasn't been widely discussed. Over the last several years municipalities and water purveyors have been evolving their standards for backflow prevention valves on commercial facilities.

The evolving guidelines are increasingly conservative - assigning higher risk profiles to applications and requiring reduced pressure zone (RPZ) type backflow prevention assemblies (BPA) for more applications.

There are several contributing factors, including:

• Increased awareness of backflow situations through AMI data
• Growing attention to conservation and environmental concerns
• Awareness regarding potential cross connection risks with traditional double check assembly (DCA) type BPAs

And as attention focuses on the type of BPA that raises secondary questions regarding the optimal location. Water purveyors, civil engineers, building owners, contractors, fire departments, mechanical engineers and insurance underwriters are all increasingly attentive to the location of valves.

But the body of "best practice" knowledge has mostly just been passed anecdotally within water districts. At Safe-T-Cover we hear snippets from districts all over the country, and we realized these were wide scale trends. So we undertook to create a resource which would help anyone in the commercial plumbing and waterworks communities find a consolidated overview of these trends in a single guide.

"We're thrilled to release our new guide" says Craig Carmon, president of Safe-T-Cover. "We've literally spent more than three years researching these trends nationwide. We've collected input from regulators, purveyors, inspectors, civil and mechanical engineers, attorneys, underwriters, contractors and more. This is the first consolidated reference we're aware of regarding these trends in backflow preventer valve selection and location.

The 15 page illustrated guide covers key topics including:

• Water supply safety
• Types of backflow
• Types of valves
• Approaches to backflow management
• Design risks
• Use cases
• Regulations and guidelines
• Common installation locations
• Trends
• Liability and risk considerations

"The default location used to be a mechanical room or vault" adds Carmon. "But there's awareness growing that those locations are often poorly suited as the valve selection evolves. Today's valve specifications increasingly require above grade exterior placement rather than in vaults which often flood, or mechanical rooms where the RPZ drain requirements are simply impractical."

This guide is designed for anybody who's specifying, buying, testing or relying on a commercial supply backflow prevention valve. It takes the reader through the changes, background rationale and factors, and the implications to their existing and future projects.

Randy Holland, Safe-T-Cover's expert resource for water authorities and the civil & plumbing engineering community adds "I speak almost weekly with engineering teams at water districts and consulting firms. I'm amazed that as common as these trends are, there's been no common resource. I'm really excited to bring this guide to the community. Between this BPA trends handbook and our program to help water districts create standard design details, we're taking the lead in empowering the professionals that are entrusted with water conservation and safety."
