Backflow Prevention: The Last Line of Defense for Plumbing-System Safety

By JOHN VASTYAN, Common Ground, Manheim, Pa.

In a piping system, water is intended to flow in one direction: from the supply to the point of delivery. Danger lurks when the pressure in a system exceeds the pressure of the supply. Anytime pressure in a system drops, even momentarily, the system is subject to backflow, back pressure, or back siphonage, opening the door to contamination. This can happen all too easily when a water main is shut off, a water main is broken, or water demand surges in a specific area.




Proposed Facility Smart-Grid Standard Open for Public Review

A proposed standard intended to create smart facilities in support of a national smart-grid effort is open for an advisory public review ending Sept. 3.



HIGH EFFICIENCY BOILERS FROM BRYAN STEAM Bryan Steam's HE Series, high efficiency version of forced draft gas fired "Flexible Water Tube" Water Boilers, features a guaranteed efficiency of 85% without complications of condensation. The high combustion efficiency results from a uniquely designed integrated extended surface heat extractor supported by 7 sq. ft. of heating surface per boiler horsepower. HE-AB and HE-CLM Series Boilers offer inputs from 900 MBH to 3,000 MBH, while the HE-RV Series offers 3,500 MBH to 8,000 MBH. The Bryan "Flexible Water Tube" design provides for extremely fast internal circulation for maximum heat transfer and operating efficiency. Click here for more.
