If the piping is inside the building it can NOT be schedule 40 PVC for the supply lines.
That is the way to go, although the thought of cutting a bunch of 6" pieces with a hacksaw isn't appealing. The only place I looked for strut material was a local A/C supply house I use, but they only sold it in 10-foot lengths. We've got a McMaster Carr outlet here -- I generally don't even think about them because they tend to be expensive. I tried to see how much the cushioned clamps are, but their web site search seems to be steam-powered today.Actually, the material is surprisingly inexpensive.
I suppose that's "code" -- any idea what the reasoning is behind that?If the piping is inside the building it can NOT be schedule 40 PVC for the supply lines.
McMaster 304 stainless strut clamp, vibration dampeing part #3262544-T44, $5.72 each, this will last much longer than you or I will, Zinc Chromate plated will last a couple hundred years, and they are $2.19 each. (and re: is it rated for outdoor use, lol, are you really going to ask that rookie of a question???).
BTW, yes, they are rated for outdoor use, "sad this question would come up by someone who claims to know everything, not sure if this person has ever used unistrut" and yes an ugly piece of scrap wood stripped from a shipping pallet or just about anything jammed between the wall and the pipe may work, but considering the extremely low cost of doing the job in a way that looks nice, is proper, and the fact that the parts are readily available, why not do it right?
Whereas CPVC is rated for ...er... 200°. And most residential hot water comes out of the water heater at 125° or so. Whoop-de-doo. The difference is more important at my house, since the hot water starts out at 160°+ on a sunny day.The problem is that PVC is not rated for temperatures above 185 degrees...
Man you are so easy. LOL You can't really think I don't know about Uni-Strut. And you'd use ugly zinc rather than powder coated. That's all hard for me to believe but you are young with a huge ego and money driven and from California.McMaster 304 stainless strut clamp, vibration dampeing part #3262544-T44, $5.72 each, this will last much longer than you or I will, Zinc Chromate plated will last a couple hundred years, and they are $2.19 each.

You should have Tom check on his claim of PVC being rated at 185f. We are talking about sch 40 PVC here.Whereas CPVC is rated for ...er... 200°.

BTW, why do you want him to run the copper back against the stucco wall when that's the same as laying it on concrete? And, do you want him to use the strut running along the wall or out from the wall? Do you want him to anchor the strut and if so how?
I wondered about that, but it made my whoop-de-doo sound better to accept that figure. Sch 40 is generally accepted to handle 140°F OK, but has to be pressure-derated as the temperature rises above its base rating temperature of 73°F. At 73°F, 1" Sch40 PVC has a maximum working pressure of 450psi; at 140°F that drops to 99psi. For 1" CPVC, it's 400/200. (Full disclosure: I didn't have all this in my head.)You should have Tom check on his claim of PVC being rated at 185f. We are talking about sch 40 PVC here.
You assumed in the post I repiled to with the above quote that I said to jam a piece of wood between the wall and the copper... he said he was afraid of laying the copper ON CONCRETE, then questioned having it against the stucco.How is suggesting using unistrut suggesting mounting it dirctly to stucco? Sometimes (more often than not) you make no sense. Then again, when your main purpose for posting is to find a reason to disagree with any of the advice givers, rather than offer productive advice to the OP. As to powder coated vs. zinc, ... I thought I recomended Stainless. I only posted the cost of the Zinc chromate since it will last hundreds of years, and cost half as much, and considering the price difference is insignificatnt, unless you are on such a tight budget that you can only afford to use a hammer to beat pieces out of an old pallet to make your mounts. lol
This is awkward, but...
