Your Resource for PEX Plumbing Systems
On Jan. 22, 2009, the California Building Standards Commission (CBSC) certified the Environmental Impact Report (EIR) on crosslinked polyethylene (PEX) tubing and unanimously adopted regulations approving PEX water distribution systems into the California Plumbing Code, set to take effect Aug. 1, 2009.
Now contractors and consumers finally have access to an environmentally superior product that will provide a durable solution to the state's aggressive water conditions, while meeting California’s high standards for drinking-water quality.
Conducted from October 2007 through December 2008, the EIR evaluated PEX tubing on its impact on air quality, water quality and performance, as well as PEX tubing installation, use and disposability and manufacturing processes in the areas of waste, recycling, energy consumption and natural resources.
The EIR concluded the adoption of PEX tubing into the California Plumbing Code with proposed regulations would be “an environmentally superior action with respect to public health and hazards, water quality and air quality.”
In fact, millions of feet of PEX tubing are already in service in plumbing applications throughout California, due to the fact that 180 municipalities and counties within the state have already approved the use of PEX tubing.
Uponor Lead-free Plumbing Systems
To continue our mission of supplying our professional partners with building system solutions, Uponor is also launching a complete line of lead-free brass transition fittings and valves that meet California lead-free legislation and exceed the requirements of the United States Safe Drinking Water Act. Combining these fittings and tubing with our extensive engineered plastic (EP) offering and our innovative ProPEX® Out-of-the-Wall Support System provides a complete lead-free plumbing solution from the inlet to the faucet.

What is PEX?
An Uponor plumbing system features Engel-method crosslinked polyethylene (PEX) tubing. This is a flexible plastic tubing product that has been used for more than 35 years in radiant floor heating, plumbing and fire safety systems.
PEX is classified into three categories: • PEX-a (Engel or peroxide method) • PEX-b (Silane method) • PEX-c (Electron beam or radiation method)
The PEX tubing industry considers Engel-method PEX-a tubing superior because the crosslinking is done during the manufacturing process when polyethylene is in its amorphic state (above the crystalline melting point). Because of this, the degree of crosslinking reaches around 85%, resulting in a more uniform product with no weak links in the molecular chain.
The properties in PEX-a tubing make it the most flexible PEX on the market, allowing for the tightest bend radius available — as little as 3½" for ½" tubing. Its flexibility also greatly reduces the instance of kinked tubing. However, because of the thermal memory of PEX-a, if a kink does occur, a simple shot from a heat gun returns the tubing to its original shape.
The Unique ProPEX® Connection
The shape memory of PEX-a tubing allows it to expand and then shrink back to normal size. This allows for the use of Uponor’s unique ProPEX® expansion fittings, which capitalize on the shape memory of PEX-a to create strong, durable and reliable connections without the use of dangerous torches, glues or solvents.
USA "L" HARD COPPER
|
In order to help homeowners, potential homeowners and consumers make educated decisions when it comes to plumbing, the CDA has developed a 12-point Plumbing Test. Not surprisingly, copper is the only plumbing material that can answer "yes" to each of the following questions. How does your plumbing match up?
The CDA 12-Point Plumbing Test
- Does your plumbing material have a long-term, proven performance record?
- Is it permeable; can it block contaminants from penetrating its walls?
- Can the joints withstand rapid pressure and temperature changes?
- Will it perform well in all weather, and is easily thawed, if necessary?
- Does it resist punctures and abrasions and not become brittle with age?
- Does it inhibit the breeding of harmful germs?
- Will it not burn, or give off smoke or toxic fumes, when exposed to fire?
- Will it withstand the weather and the sun's ultraviolet rays in outdoor applications?
- Is it maintenance-free and has a low lifetime cost of ownership?
- Will it add to your home's resale value?
- Does it have nationwide approval of building inspectors and engineers?
- Does it have inherent quality and value, or offer 'false economy' like some competing materials?
