Is the DWV stuff really inferior?...I have read a couple posts on not wanting to use it and found out (after not knowing what it was) that it is not for pressure.
Well, I can't even find anything else at my local homedepot or lowes.
You can find some fittings, but most of the stuff including pipe (which is what I need) seems to not even be carried anymore. At least not in 10 ft lengths.
So what is the deal with the DWV stuff? It is still sched. 40. I need to buy 150ish feet to hook up my solar panels and don't wanna do the wrong thing if there is really something wrong with the stuff.
If it shouldn't be used...what should I use?
thanks for any input.
