Backflow prevention is the unglamorous side of commercial water management — it guards against problems, and is only noticed if something goes wrong. Recent innovations in backflow prevention system design, however, have attracted attention for their improved performance, protection against liability, ease of installation and advantageous lifecycle costs.
Backflow prevention & pressure regulation help safeguard buildings from disaster
Water efficiency and sanitation for a building or campus, whether new construction or retrofit, are best achieved through a whole-building approach, with a proper emphasis placed on connectors that regulate pressure.
Protecting the integrity of buildings’ plumbing systems
Nationwide, the U.S. loses 1.7 trillion gal of water each year, which the U.S. Geological Survey estimates is equivalent to 16% of treated water never reaching the tap. This is the direct result of the aging and rapidly deteriorating system of pipe and plants that comprise U.S. water infrastructure.
Water-efficient fixtures help homes find significant water savings
Through the partnership, the organizations hope to advance the professions of water treatment & plumbing engineering
The American Society of Plumbing Engineers (ASPE) and the Water Quality Assn. (WQA) have signed an agreement to promote and advance three WQA standards for recognition as consensus American National Standards by the American National Standards Institute (ANSI):
The RP 340 is a small, light press tool for joining copper, stainless steel and PEX tubing, and black iron pipe. It has increased user maneuverability and a service-interval cycle of up to 42,000 cycles. It comes standard with new 18-V advanced lithium 2 batteries and an optional AC power adapter. It offers bolt sensor technology to ensure jaws and attachments are securely connected to the tool. Other features include a quick cycle time, operation in extreme temperatures and jaw rotation up to 270 degrees.
FC-Cutters are available in 1.5- and 2-in.-diameter options for cutting different pipe sizes. They cleanly cut ABS and foam core PVC pipe. Featuring an extended handle for leverage and easy rotation, the cutters need only to be snapped onto a pipe and rotated once for a precise cut. They do not leave burrs, and each cutter comes with an extra blade. Replacement blades also are available.
Students in Maine fix water leaks and recommend efficiency measures during Fix a Leak Week
The Kennebec Valley Community College (KVCC) and the International Assn. of Plumbing and Mechanical Officials (IAPMO) Green Plumbers Training program are teaming up to fix water leaks and recommend efficiency measures during the U.S. Environmental Protection Agency’s (EPA) Fix a Leak Week March 18 to 24.
The Bell & Gossett ecocirc wireless circulator system uses electronically commutated motor technology and operates on as little as 14 W of power. A valve is installed under the sink or other water outlet, farthest away from the water heater, where hot water takes the longest to arrive. The valve is battery operated and equipped with an onboard temperature sensor and wireless RF transceiver that communicates with the circulator pump mounted to the water heater or hot water source.
The Close Quarters ASTM F1807 PEX crimp tools feature handle openings up to 70% smaller than standard, providing maneuverability in tight spaces. Available in ½- and ¾-in. sizes, they are ideal for making connections in potable water and radiant heating applications. Features include durable, glass-filled polycarbonate E3 handles; a built-in, Go/No-Go gauge; and an adjustable lock screw. They are made for use with ASTM F1807 copper crimp ring PEX tubing connections.
In an effort to ensure that America has the cleanest water possible, on Jan. 4, 2014, a new law reducing the amount of lead allowed in plumbing products will go into effect. Williette Nyanue, assistant editor for Water Quality Products, recently spoke to Barbara Higgens, executive director of Plumbing Manufacturers Intl. (PMI), to discuss the implications of the law and how manufacturers are preparing to comply.
