Anybody have any experience with this stuff. Been used in Europe since 1980.

It has been widely used in residential around here (Cincinnati) for several years, but I am just now seeing it in the specifications on commercial project more frequently. It is cheap, installs easier than sweating copper fittings, and most guys run it right in the concrete floor slab instead of running it inwall or overhead thereby eliminating the need for hangers and supports. If I were building a house, I wouldn't hesitate to use it. We install very little of it as we do exclusively commercial plumbing, but we do use it when allowed.

Does it pass residential code in Cincinnati? I like what I see, seems easy enough and the crimping tool is not that expensive. I sure am tired of sweating cooper, plus this looks like you can make more direct runs etc.

I used it on a repair for the kitchen sink hot supply line. Easy as can be and they make a connector to go from brass to PEX.

Yes, many new construction residential guys use pex everyday here.

ETA: As a matter of fact I am getting ready to use it in a new 100 bed nursing home we will be starting in the spring.

Wow - I knew I would get great info here.

Long story, but my sons house he bought last year, PO re-ran the plumbing in copper below the floor joist in the garage. This area is about 7' X 10' and feeds the bath & kitchen above. Of course the garage is un-heated. We had enough ceiling height, so I dropped the ceiling, insulated the pipes as well as cavity, with R30 attic insulation below them plus vapor barrier and dry wall. There is also a heat run now in the box, which I tapped a small amount of air to help heat the cavity.

It all worked well until we hit the -10 temp this week, sure enough the pipe closest to the garage door froze. I have not been able to get over there yet to see if we have a burst pipe yet, but no water leaking.

I am thinking of re-running in PEX keeping the runs as close to the upstairs floor and through the joist as possible. I am also going to foam insulate the garage door.

Thoughts???

Yes. All of my plumbing subcontractors use pex.

My entire house uses this, it's looks like it made everything a lot easier. And repairs will be easier down the road I think.

Here's the manifold

You can turn off each line individually which I like

Forget the crimps and crimping tool. There are fitting called gator bites that are made for pex tubing and they are awesome. I have used them and there is nothing that could be easier. They sell them at my local lowes hardware.
