Is PEX safe for drinking water 2020?
The inner pipe for drinking water is made of a plastic called cross-linked polyethylene (PEX). There are no health risks associated with drinking water from PEX pipes. A few types of PEX-pipe may cause prolonged undesirable taste and odour if the water remains in pipes over time.
Does PEX pipe cause cancer?
They found that each type caused odors exceeding the Environmental Protection Agency’s guidelines, and leached chemicals such as toluene, which is neurotoxic, and MTBE, a carcinogen that’s been banned as a gasoline additive, but is a byproduct produced during PEX pipe manufacture.
How long does PEX last?
Additionally, long-term testing programs on PEX have shown that it has a potential lifespan of more than 100 years. So, while copper systems may have to be re-piped every few years or decades due to corrosion and pinhole leaks, a PEX system can last 10 times longer — or more.
Which is better copper or PEX?
Copper is more likely to freeze and break. Having a degree of flexibility, PEX is able to expand if the water inside it freezes, making PEX more resistant to freeze-breakage.
Is PEX pipe BPA free?
PEX is a form HDPE (high density polyethelene) also know as cross linked polyethylene tubing. … The use of BPA in plastics has come under fire for its adverse health affects and although PEX does not contain BPA it contains a number of other chemicals.
Where is PEX not allowed?
Pex not being allowed in commercial or industrial buildings, and thus not in residential buildings deemed “commercial industrial”.

Should PEX hot water pipes be insulated?
Pipe insulation is a prudent step to take. … That’s because PEX pipes—basically a type of plastic—are physically different from other common piping materials. They are very flexible and less prone to cracking. They also contract with heat, cold, and sometimes even water flow.
Why is PEX plumbing bad?
PEX failures Piping fails when the pipes are exposed to chlorine that is within the water, exposure to direct sunlight before its installation. Furthermore PEX pipe is vulnerable when it comes in contact with such solutions as petroleum products and oxygen. It can leach toxic chemicals from pipe material also.
What are the disadvantages of PEX?
PEX Plumbing DisadvantagesPEX may leach BPA and other toxic chemicals. … PEX is extremely sensitive to UV light. … PEX can be damaged by chemicals and pests. … PEX can’t be installed in high heat areas. … PEX is semi-permeable, which means liquid can enter the pipe.
Should I use PEX A or PEX B?
Flexibility – PEX-A is the most flexible, allowing for it to be fastened by cold expansion, which allows the end to be fluted prior to inserting the fitting. PEX B is not expandable and you should never expand the end of a PEX-B pipe. Kink-Resistance – PEX-A has the greatest resistance, PEX-B the lowest.
Which PEX is best for drinking water?
There are no performance differences between red, white, blue and white PEX and all are intended for use in potable water systems. The colors can be used to easily distinguish between hot and cold distribution lines. Orange PEX pipe is an oxygen barrier PEX pipe used only for hydronic heating applications.
Can you use blue PEX for hot water?
Color-Coded: Red PEX pipes can be used for hot water supply lines, blue PEX for cold water supply, and white for either hot or cold. These colors are just for your convenience. Plumbing code does not require the pipe color to match the type of water supply.
Is PEX pipe legal in California?
— The California Building Standards Commission has given its approval for the use of PEX tubing in potable water systems in the state following its review of a Second Revised Draft Environmental Impact Report (SRDEIR). …
Why is PEX banned in California?
PEX was banned by California’s Building Standards Commission because there was a concern that some chemicals may leak from the pipe into the water. So, the authorities of California banned the PEX thinking that it may cause unnecessary exposure to chemicals or carcinogens which may lead to dangerous effects.
