PEX-AL-PEX (Kitec/IPEX): dezincification of fittings PEX-C (Nibco/CPI/DuraPEX): cracked, leaking pipes PEX-B (Zurn & Viega): dezincification of fittings PEX-A (Uponor/Wirsbo and Rehau): dezincification of fittings and chemical leaching/odor (AquaPEX only) Anyone with a prejudice towards one type or brand of PEX and fondness of another should know that not a single major PEX pipe/fitting system used in the US has been problem free. While a reader may find that our share of experience is similar to that of others, we’ll try to provide not only a description of the common and not-so-common problems, but also the steps to prevent and remedy them where possible.īefore we proceed, we ask the reader to keep the following 3 things in mind:ġ. CPVC, leaks, bursts, kinks and you name it. Having been in the PEX industry for many years, we’ve heard it all – the PEX-A vs PEX-B debates, PEX vs.

The good news is that a PEX system can be made to last beyond the 20-25 standard warranty and perform as needed when properly understood and installed. We also have ProPress adapter flanges in bronze and copper for sizes 1' to 4'.With increasingly larger portion of contractors and homeowners turning away from copper and CPVC and switching to PEX, we’re inevitably facing the reality that PEX is not a final solution for the plumbing industry, and like its predecessors and competitors, has its own ups and downs. Viega offers a bronze ProPress dielectric union with an EPDM flat gasket and sealing element for sizes ½' to 2'.

Insulating components prevent the two metals from touching. The other end has a female copper hub fitting, which slides over onto the copper tubing. This has a threaded steel female pipe fitting on one end, which is threaded onto the male threads of the galvanized steel pipe. We recommend a transition fitting called a dielectric union. This is one of those joinings that requires protection against galvanic corrosion. Galvanized, which was common in houses built before 1960, is susceptible to corrosion and is now being replaced with copper or other material. One of the most common metal-to-metal joinings is copper to galvanized steel in potable water systems. Different jurisdictions have different rules.

While there are general rules of thumb to follow, the best way to ensure compliance is to consult the local code book. That’s why joining dissimilar metal pipes requires using the correct insulating transition fittings. Whenever two different types of metal come into contact with each other or an electrolyte (like tap water), one of the metals might begin to corrode. Problems occur when dissimilar metals are joined without consideration to their compatibility. Particularly in older structures, a contractor is likely to find a mix of piping materials, often the result of repairs or incremental upgrades, rather than complete system replacements. Depending on the nature of work (residential, commercial, industrial), a plumbing contractor is likely to encounter a dizzying variety of materials: copper, different types of PEX, galvanized steel, stainless steel, brass, PVC, CPVC, cast iron and ABS. Knowing the correct method for joining dissimilar materials is one of the most challenging things for a contractor to learn. That’s only a few more than the number of pipe-to-pipe combinations a contractor is likely to face on the job. There are 43 quintillion possible configurations of the Rubik’s Cube.
