IDOD is just a high-quality galvanized pipe that has a nice alloy layer of zinc and steel on the surface because the pipe is heated to the same temperature as the zinc bath before it is dipped. There is no flaking of the zinc "coating" that you get when you roll grove lower quality pipe (e.g. stuff from China) so it has a better corrosion resistance.
I don't think that there are any listing restrictions. Paul J. Pinigis, P.E.

We have never used the IDOD product and have the following questions for any of you that have: What is the preferred head out let?(Side outlet coupling?)(Snap-o-lets between?)(other?) Any specific listing restrictions with this product? Do you order pre-cuts from the factory or cut your own? Any other suggestions?
