  • PEX may leach BPA and other toxic chemicals.
  • PEX is extremely sensitive to UV light.
  • PEX can be damaged by chemicals and pests.

How long is PEX supposed to last?

40-50 years
Fact: The life span of PEX tubing can vary based on frequency of use, water quality and water temperature and has an average life expectancy of 40-50 years. Some factors, such as exposing tubing to sun or water temperatures beyond tested levels, can significantly damage tubing and reduce its life span.

Is it better to bend PEX or elbow?

How tight can you bend 1/2 PEX?

PEX tubing can be bent slightly to accommodate curves. But do not bend the tubing tighter than a radius that’s six times the size of the tube. For example, a 1/2-inch tube can have a three inch bend radius. All 90-degree turns should have bend supports.

Does PEX piping deteriorate?

Can you use a heat gun on PEX pipe?

Type A pex is the only one that can be unkinked by application of heat from a heat gun. But, it won’t improve the turn radius. Each size and type of pex has a minimum turn radius and you should be able to bend it to that without doing anything special.

What are the pros and cons of PEX tubing?
