Why not stick with black poly? Can't the leaking spot be repaired? I

would guess that the leak is at a fitting that can just be replaced.



Because black poly is not the best material. If it is deteriorating

you'll be forever patching. Pex is good for 30 to 50 years.

And your reference that poly won't last a similar amount of time is?

It is already deteriorating in the OP's water line. Patching it is only
a temporary fix.


It's been on my house, all my neighbors houses for 30 years now and
I haven't heard of a single failure. If it doesn't perform well,
rather odd it's still approved and used. And I'd also point out that
you're comparing something that is relatively new, ie PEX, to something
that has been widely used for 30+ years. There have been other new
plumbing materials that were thought to be great ideas, where after
a couple decades of use, they turned out to have major problems.
I'm not saying that PEX wouldn't be perfectly fine, just that until
it's been in that kind of application for 30 years, I don't think
you have the data that shows it's any better.


It has been in use for over 40 years now. Pretty well proven. It is
not relatively new IMO, but well established.
