Where to insulate PEX Plumbing Pipe tubing will it freeze bust should be insulated in attic outside 

The most vulnerable areas of PEX is at the connections. Sometimes these connections are not made properly and can fail as a result. PEX should have as few fittings as possible in the system for this reason. All plumbing systems have a service life, based on installation technics and the quality of the tubing and fittings. The lack of an Expansion Device on tanked water heaters can also cause plumbing failures. Most homes built today are plumbed with PEX and there is also different types of PEX Pipe as well.
