PEX fitting failure
nev

I have had several stainless steel clamps fail on hot water PEX lines.
Brass fittings corroded. Well water is source. Plumbing about two years old.
Any thoughts?

Replace the crimp type fasteners and crimp tool with the expander tool and the PEX outer ring. You still use the brass barbs. Have your well water tested, it may be acid and you may also be getting air into your water lines.

Your story doesn't sound good, even without knowing what you used for PEX and clamps.

Did a licensed plumber do the job? If yes, call him to see what he can do.

What kind of clamps used? domestic or imported? brass or other "metal"?

Are the pipes bursting, cracking, leaking or whatever too? call the manufacturer. There have been a lot of class action suits in this industry.

I install COPPER only, and don't have these problems.

So how can air in the system cause corrosion? Thanks

Air contains oxygen which is needed for corrosion.
