Looked at a repipe yesterday that has FostaPex.

Since there are no valves, save the ZVs, on the loops I need to cut some in. VERY close to the pressed fittings.

Wondering, will MultiCor press fittings fit ? Or do I need to hunt down a supplier ?

    FostaPex is

    a basic pex tube with the aluminum wrap around the outside.

    To make a fitting you need to remove the outer layer. Viega has a tool to do that.

    In a bind I have used my tubing cutter and pocket knife CAREFULLY, to notch and skin the outer layer.

    No you have a regular pex diameter and I have again in a bind, used a regular (other brand) copper crimp ring and fitting.

    The Viega fitting does have a tighter ring count, but for low pressure hydronics....

    That Viega system if the envy of many competitors. Nice looking and works. A bit more effort to assemble.

    Ideally you could find or borror the correct tool and fittings :)

    \"ideally\" :)

    That's funny :)

    This guy quoted 60% of my price, then crowed about taking my work. I guess it made him feel good to take a job from the last employer to fire him :)

    Now he's done something I've never done, been fired from a contracted project.

    Even with the lack of valves, etc., he worked about a month for what I can see is about a grand over material. And that was almost his complete quoted price. I guess when you don't do much in a week, you're not worth much for the week. Part of why I fired him.

    We'll see who laughs last :)

    Thanks guys, I'll start hunting parts.
