Plumbing and PEX

Before the forward salon settees are permanently installed, I need to give thought to the hose runs for the domestic plumbing system. For ease and flexibility of installation we have chosen PEX tubing for the hose runs. This stuff is commonly used in RVs and household radiant floor systems. The tubing is a tough polyethylene material that fits a variety of "friction" fittings for valves, elbows, couplings, reducers, etc. No barbs or hose clamps. There are many manufacturers of these fittings made from materials like polymer plastics and brass. Name brands include Watts, SharkBite, SeaTech.

The galley and both heads will have hot, cold and raw water (seawater) service.  There will be pressurized raw water service to the bow and stern for deck mounted washdown fittings (perhaps cold fresh water too).
