I am looking to use a push-button on-demand hot water re-circulation system with a dedicated recirculation return line as part of my remodel.
I've read in a couple posts on this site that high water velocity can lead to pinholes in copper, and in the same post, some persons said that is not true and that it is only water chemistry. I've had pinholes in a different home with normal flow rates.
The pump options I'd be using could flow up to 8 or 18 GPM, and I was leaning towards using 3/4" copper for a variety of reasons (though PEX could be possible on the hot side).
Should I have any concerns with this type of water flow rate on copper or PEX pipe and fittings, from a longevity perspective?
