I replaced my fresh water systems in several steps—my main goal was to get rid of PEX and to use standard hoses, standard hose fittings, and good clamps. Our situation is quite different that most of the boaters on this list. We live aboard full time and we cruise south every winter—so, we don’t need to concern ourselves with freezing temperatures. In the past I have had several fresh water leaks with the PEX fittings and I wanted them gone. However, some still remain under my head sink—it is a tough spot to get in and change them. I used reinforced 1/2-inch vinyl hoses throughout. I still have a fresh water leak that I think is in one of the original PEX hoses but I can’t find it.
