Does PEX plumbing 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.
Is PEX 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.
Can I run 3 4 PEX to shower?
3/4″ pex is somewhat larger than 1/2″ copper, and 3/4″ copper is probably a good size for a bathroom group. If the pressure drops on the cold side (sink and someone flushes the toilet), that may be enough with 1/2″ line to cause a pressure balance valve to throttle the hot side while it’s also feeding the shower.
Is PEX legal in California?
California plumbing code now accepts PEX pipe.

What is the lifespan of PEX pipe?
100 yearsAdditionally, 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.
Can I use blue PEX for hot water?
Blue PEX pipe carries cold water. White PEX pipe can be used for either hot or cold water. … There would be no problem, for example, using blue PEX for hot water lines or red PEX for cold water lines.
