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 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.
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.
Is 1 2 PEX big enough for shower?
As long as the supply lines for the shower tie into a 3/4″ line, 1/2 ” will be fine.
