I'm no exoert, but I don't like using PVC anwhere on a boat. As it
ages, it gets brittle and can break. For underground or in a house,
this isn't an issue. But in a boat, there is constant vibration, etc.
that can cause it to crack when it looses its' elasticity.

The only time I've ever had uncontrolled water entering a boat, was when
a PVC adapter that a previous owner had put on a through hull failed
(it's amazing how fast the water comes through a 3/4" thru-hull when
this happens).

This is a very short list/description of what I'm going to install on my
boat.

Any suggestions, changes or recommendation are more than welcome.

Thanks in advance

Fresh water supplied through the two deck fills (star or port side), or
through pressurized shore supply (with pressure regulator).



On dock - fresh water shore supply can be connected directly to sea water
system.



Head - water from sea water system - discharge to holding tank or outside

Two seacock 2" - one for IN and one for OUT.



Separate faucets for seawater only in galley and head sink.



As a backup - galley and head sink have foot pumps for fresh water - not
pressurized through the Y valve for seawater optional.

Questions: What kind of water heater (diesel fuel?), which toilette? I
didn't know that I have to many to choose from - thanks Peggie :-), What
about strainers/filters and check valves - I have to install some of them.
