I did the following work quite some time ago. Yesterday I had planned to sweat the elbow onto this 1/2" copper line and the stub into the near cabinet - but the weather turned better than forecast, so we went outside instead.
This is the fresh water supply line from the holding tank, to the planned manifolds under the galley sink. There was no room to run it entirely behind cabinetry, so we had to make it pretty, like with the copper 1.5" grey water drain line elbows near the range/fridge.

Note its double use, as it also becomes a towel rod. The mounting brackets are placed for proper support, aesthetics and as prevention for a towel sliding over in front of the heater.
These are the pieces I worked with to make up the design.


And then stained "natural" (clear - for the blonde wood contrasting) and simply sprayed with a clear-coat poly-like paint, which was faster than waiting three days for three coats of brush-on. The pieces are not as "thick coated looking" as much of the rest of the interior poly treatment, but they're satisfactory.
Here in the fresh water cabinet, the braided hose comes off the pump and loops around to the copper line stub, attached with a Sharkbite connector. I've installed hose clamps since this photo was taken.

With a Sharkbite, I can leave the copper line stubbed just like this, allowing smaller holes in the cabinet faces than if a fitting were sweated on the end. And that also still allows easy piping removal, if needed in future, for cabinet disassembly (tank change, etc.)

Sliding parts into place.

Checking lengths and fit.

Here's the Sharkbite on the short stub side near the water heater.

Post Sharkbite, the material changes over to 1/2" CPVC, with the same outside diameter as the copper pipe. From here it will run into nearby manifolds built for cold and hot, which in turn will contain "shut-off valves" to each of the connections.
Five Cold Connections: City Water Input, Outside Sprayer Port, Galley Sink, Hot Water Heater Supply, and Bathroom line.
Four Hot Connections: Outside Sprayer Port, Galley Sink, Hot Water Heater Return, and Bathroom line.
But first, I should get this sweated.

Incidentally, the two bathroom lines will exit this cabinet area and run up the exterior door trim board nearest the counter. From there they go overhead (over the doorway) and into the bathroom, where they turn into some fancy stuff we won't talk about yet.
