If your concern is the water quality out of the RO unit, rest assured you will not have a problem. Copper water pipes are the preferred type for potable water everywhere. Also, copper is a very large molecule, and would be very efficiently removed by your RO membranes.
I don’t know about you Maramu, but on our SM most out the interior fresh water plumbing is copper.

Wondering on views to antifouling of through hulls that are used for drinking via reverse osmosis ?
We have just copper-bottomed including a new thru hull for a new RO unit on our older maramu
I believe most owners on the forum have SM Sea chest arrangements
