RE: 25 foot rule?
Plumber, you are correct about the Intermod, and yes that is what I was getting at in my original post. But if you look a couple of posts below the one that you quoted from, you'll see that I admitted that I was on the wrong path - i.e., The Intermod issue is not being discussed here.
Just trying to keep folks on track, and not follow the wrong tangent that I inadvertantly started...
