duo-pex

[pj4]

putting in an outdoor stove. has any one had experience with duo-pex for underground use? not sure if it it oxygen rated.should i stick to the metal reinforced hose, such as wirsbo? what do you know that does not work?

Our outdoor boiler has the nibco dura pex. First year with it, but thats what they used for the install.

We used the al-pex for our install. If there is any cast iron in the system the pex must have the oxygen barrier.

Just going to install mine tomorrow, it is the pex-al-pex wrapped in insulation and stuffed inside a 4" drain tile. The al-pex is much easier to work with since it is easily bent and formed and has memory to it. The stuff without the aluminum liner is a bear to work with since it always seems to want to coil back up in the roll when your trying to lay it down.
