What could result from kinked PEX runs during re-piping?

Explanation:
Kinks in PEX piping create localized narrowing where the pipe is crushed or sharply bent. That reduced cross-sectional area increases resistance to flow and causes a drop in pressure downstream. The bend also places unusual stress on the pipe wall, and under normal operating conditions those stressed areas can crack or leak. So kinked PEX runs will restrict flow and raise the risk of leaks. To avoid this, route and support PEX so it remains smooth and free of kinks during installation.
