Should you insulate PEX pipe?

Pipe insulation is a prudent step to take. Not only does insulation promote energy efficiency, but it can also reduce potential problems with moisture and condensation. … That’s because PEX pipes—basically a type of plastic—are physically different from other common piping materials.

Is PEX OK for drinking water?
