    I have a repair job; bring this new home up to code by getting a permit, installing a backflow, adding 4 valves and removing home owner installed HD junk. My problem is that I had to call a plumber to splice a "T" in this PEX line; $85. Has anyone seen a line run like this?

    Yup. not too often, but it's catching on. it's similar to poly pipe in the installation (barb fittings and clamps). if you need copper for stability there are adapters that'll take you from pex to copper. (you're plumber should have the stuff)

    Turn it around and bill the customer. The tools to mess with pex are expensive, and so is pex itself. Even though it looks cheap, its actually super - expensive. I think it can expand 3x and shink 1\2 without breaking.

    You might have been able to use a PEX compression tee, and saved a few bucks. Plumbers will use fittings specific to the brand of pipe, even though the tubing is made to SDR-9 specs.

    You learn this stuff the hard way, by breaking it, then fixing it. I guess the plastic compression fittings match the expansion rates of the pipe, so temperature changes don't create leaks.

    Any house built here in the last 15 years or so has pex plumbing and main. Before that we had Poly B. Copper is a pretty distant memory around here. Crimp rings and crimpers for pex are pretty much standard equipment for all irrigators around here. Most houses have 3/4" main and meter. Some high end stuff is now getting 1" and 1 1/2" mains. For those, we have a plumber do the T as the fittings are not at all alike and the "standard" crimpers are only good for 1/2" and 3/4" pex.

    With the price oc copper, pex is becoming standard and much faster to install.

    The only problem is that the pex crimper for 1 inch is very large and hard to manuever in the tight spaces in the basement ceiling. You need to plan ahead and preassemble components that go into tight corners. The nice thing is that you don't have to lay in a straight line. Much easier to go around obstacles.

    Pex reminds me of Quest. Was it Denver that did their city mains in the stuff, and wind up tearing up miles of street when it started to fail?

    I'll still take a welded joint any day, whether it be glued, soldered, or even arced.
