It's a flexible polyethylene tubing, not all that dissimilar to a garden hose, that can routinely handle the same temperatures and pressures as you'll find in your home plumbing supply system. It's cheap, very easy to work with, and approved by building codes. I was thinking of upgrading the supply plumbing in my house, but as I learn more about PEX I'm thinking about redoing it altogether. I can put in whole new system instead of just trying to patch up somebody else's mistakes.

Everything I've read says it's inert. Do you know something I don't know?

the last half dozen houses we've been using pex, easier to work with than copper, and seeing how expensive copper has gotten, it's reasonable. Now every run is a straight shot to each device. All shut-offs are in the basement, no more guessing if you have the water off or not. Saves lots of time over sweating copper.

The past couple physician offices we have opened, the contractor used this instead of copper. All accounts is that it is much cheaper to use then copper.

Last time I compared costs was early last year. At that time the material cost between copper and Pex had the Pex slightly higher but the labor was cut in half. We switched over to using Pex at that time unless copper was requested. Now with copper so much higher priced than last year, Pex is even more cost effective.
We've had Pex out there for almost two years with no call-backs.
If you count the Pex used in in-slab radiant heat then it's been five years.

I greatly appreciate hearing from those of you who have experience with PEX. Now, a specific question: I would like to use HydroPex fittings

http://www.pexsupply.com/CategoryPre.asp?cID=543&brandid=

but with regular-style hose clamps, of the type you might use on your car. I want to avoid buying the $140 "ratchet clamp tool" that's needed for the "stainless steel clamping system".

http://www.pexsupply.com/Categories.asp?cID=553&brandid=

I'd be happy to buy stainless steel clamps, but I don't see why I should buy THESE stainless steel clamps; apparently the tool gives you a calibrated amount of squeeze, but I figure I should be able to put on a hose clamp by myself...

Any comments?

"apparently the tool gives you a calibrated amount of squeeze,"

Sometimes yer tool NEEDS a calibrated amount of squeeze.

"but I figure I should be able to put on a hose clamp by myself..."

Nah. Tell your wife to leave the fence alone for a while and give you a hand. Or, a calibrated squeeze, maybe.

Prefer the expander tool with the sliding over fitting.
See if you can rent the tool from where you buy the PEX.
They have different PEX for heating and water supply.

Have been working with PEX around the house and I like it. I'm kind of cobbling things together for the moment and will have to redo at a later date, so I'm using the Shark Bite fittings. They are expensive but reusable, and easy as pie to use.

One recommendation: Don't use the long coils in a re-fit if you can afford not to. Long coils save money, but they are hell to work with. Trying to unravel a 30-inch diameter coil (that's what it relaxes to) between joists that are hung with wiring and ductwork is insane, and it's impossible to get the ends square and perfectly seated. Ten-foot straight lengths are much easier to work with, but you'll have to spend more for elbows and connectors. (I'm talking about 3/4 PEX; 1/2 is easier.)

All in all, PEX beats the hell out of sweating copper or fooling around with PVC. I had a PVC joint blow out inside a wall once because I hadn't cleaned the pieces correctly or let them dry long enough; with PEX it either works or it doesn't. As soon as you turn on the pressure you know.
