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
Acquisition meets demand for expedited plastic pipe performance and custom R&D testing
NSF Intl. acquired the laboratory portion of Jana Laboratories Inc., an engineering consulting and laboratory testing firm that serves the global water and plastic pipe industries. Jana Laboratories’ 14-person laboratory staff and 20,000-sq-ft laboratory in Aurora, Ontario, Canada will be renamed NSF Janalab and become part of NSF’s global network of ISO/IEC 17025-accredited laboratories throughout North and South America, Europe and Asia.
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
The Leak Defender automatic water leak detection system stops power to water well pumping systems in the event a leak should occur at the well tank, manifold, water heater or any water-supplied system. No external plug is required. The system is powered by the well pump and does not use a shutoff valve. Simple design and heavy-duty components ensure long-term use with low risk of failure.
Made of clear, chemical-resistant PVC and reinforced with spiral steel wire for durability, Vardex PVC hose is suited for fluid or air transfer and handles both pressure and full vacuum. Applications include chemical transfer, air supply, coolant feeds, floor cleaning equipment, material handling, water feeds and discharge, vacuum lines, spray systems, and food and beverage supply lines.
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.
The 700APD is a portable, pneumatic, heavy-duty power drive that provides power for threading pipe and conduit up to 2 in. in diameter. The safety arm absorbs forces generated during threading and frees up the operator to oil the dies during threading. Its 4-hp pneumatic motor turns at 28 rpm no load. It has a maximum torque of 400 lb-ft and uses R12+ segmental dies and dropheads.
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.
When choosing pipe or fittings for any water application, the material options can be overwhelming. This was not always the case, though: For centuries, most pipe was made of lead or wood. In fact, the word plumbing is derived from the Latin word for lead, plumbum. Although the mechanical properties of lead are advantageous for making pipe, its toxicity is an issue. Wood pipe, on the other hand, is nontoxic, but susceptible to leaks. And because wood is soft, people could easily drill into the pipe and steal water.
