Performa tubing is suitable for a full range of radiant applications in residential, commercial and industrial applications. These include radiant heating, radiant cooling and snow and ice melting.

The photo in Figure 1 shows a non-pressurized outdoor wood-fired furnace connected to a floor heating subsystem via two PEX tubes. It includes a cast iron circulator, a thermostatic 3-way valve for mixing, a bypass linking supply and return tubes, and an "expansion zone" for another floor heating circuit. This setup is in a multi-million dollar home. Are there any potential issues with the installation?

Recognizing that pipe joints are the most common source of premature leaks and system failures, IPEX has designed Centra-lok to minimize maintenance, repair and installation costs.

The simplicity of the patented Centra-lok design is also intended to offer a cost-effective vinyl-by-vinyl containment system for commercial, industrial, and municipal water and wastewater applications.

Available in sizes from ¾" to 2", the pipe is tested and proven to the highest industry standards and is fully compliant for water service applications to prevent costly errors, rework, and penalties.

The attachment cuts a wide range of PVC pipe sized from 1-1/4 in. to 8 in. schedule 40 and features a permanently fixed blade. 

Jones Stephens PEX-B pipe meets all industry standards and compliance, including ASTM F876 and F877 and NSF/ANSI 14, 61, and 372. 

PEX's shape memory allows it to expand and shrink without compromising its integrity, making it highly resistant to damage in freezing conditions. This has proven to be a lifesaver in areas like Texas during unexpected mid-winter freezes.

How do you deal with damaged embedded-in-concrete PEX tubing? Read on to find out the challenge I met and resolved.

Prepared by PPI’s Building & Construction Division, PPI TN-31 Differences Between Crosslinked Polyethylene (PEX) and Polybutylene (PB) Piping Systems for Potable Water Plumbing Applications discusses the advantages of modern PEX tubing and fittings as compared with PB tubing and fittings, which were last sold in the U.S. during the late 1990s.
