Attaching RODI to PEX plumbing

[Ryanerickson]

If your hiring a plumber I would get it cut in between the valve and (prv) the thing with the gauge, it would bypass the meter free water plus it would bypass the (prv) pressure reducing valve, city pressure you will get a little better production of water. I did this it works great. But both your diagrams look alright second pic would be easier.
