PEX & Kinks

[Pettrix]

I am having PEX installed on a new house build. I noticed one of the lines had a kink/bend in it that was straightened out but you can still see where the PEX bent and caused a crease. Is this something to be concerned about? Should I have them install a new piece there?

It would probably be fine but if it were mine they would be replacing it. If for no other reason just from a workmanship perspective.

Same. It should be easy right now.

I would say the installer needs to fix that kink, since it looks like potential time bomb later down the road.

I had a crash course in pex pipe this week.

It's super handy, but as I found out, it can be a ticking time bomb.

I'm still fighting with the camper sales place over the leak we had due to an improper install.

@Pettrix Don't even hesitate. Replace.

As @Chewwy's material points out, a kink ruins the strength and structural integrity of PEX. I would make sure that they replace several feet of the pipe to not be kinking the replacement section.

I hate to say it, but I would strongly recommend you going over ever inch of this installer's work, looking for small defects. It does not take much to generate an issue, and that photo says a lot to me about that particularly knowledge of PEX and their skill level.

Sorry.

All the best,

Peter

Properly installed PEX is ok for RVs and mobile homes that don’t have a long life expectancy anyway. I would never use it in a permanent home. Copper is more expensive but will last much longer (70+ years) if installed properly.

Does "installed properly" include something to combat acidity?
Why 10 Year Old Copper Pipes Start to Develop Pinhole Leaks.

When the potable water flowing through your plumbing system has a pH value that is less than 6.5, it can harm your copper water pipes. As the water moves through your copper pipes, it causes internal pitting of the pipe. Once those pits penetrate entirely through the copper, a pinhole leak develops.

Installation quality would have nothing to do with water quality. It does reflect on owners and builders intelligence though.
