What is PEX?

PEX is made from high density polyethylene. It contains cross-linked bonds in the polymer structure, changing PEX into to a thermoset.

How is PEX used?

PEX tubing is widely used to replace copper in home plumbing applications. Residential use of PEX has increased by 40% annually.


Why is PEX problematic?

PEX has a minimum bend radius that when not adhered to causes rapid failure of the piping. PEX can also fail due to poor manufacturing.

Most Common PEX Pipe Failures

Defective manufacturing

Defective manufacturing can occur if the manufacturer is not using processes that ensure uniform composition and thus defective.

Improper installation

PEX has a minimum bend radius, if the bend in PEX piping exceeds this minimum radius then failures can occur fairly rapidly.


Whatever the cause of the failure, our PEX pipe experts get to the bottom of the problem. We perform forensic analysis on broken PEX pipes to determine if the failure was caused by installation defects or manufacturing defects.


Want to know if a product is compatible with PEX pipe? We offer a number of A2LA certified tests including ASTM D543.


We offer on-site, non-destructive inspections of PEX piping systems then create customized remediation plans.
