Why is PEX plumbing bad?

PEX failures 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. On the other hand, fitting failure is caused by dezincification that results to corrosion and finally creating leaks.

How well does PEX hold up to freezing?

Due to its flexibility, PEX has a small margin of expansion under the damaging pressure caused by ice formation. If the weather gets cold enough, PEX pipes can and will freeze like any plumbing. However, PEX may be less likely to rupture as a result of freezing.
