Air Conditioning Water Intake and Discharge

Absolutely Roc.

I'm looking at the thru-hull and seacock with right angle connection.

I'm no plumbing engineer but I think that a Y valve or 2 valves would be needed to keep the AC raw water pump from drawing on the head line.  I installed an AC under the v-berth.  The raw water intake and strainer is also under the v-berth.  Cold air ducts go the the v-berth, starboard salon forward bulkhead, under the nav table, head, and aft cabin.  Sounds like a lot but they are adjustable.  The AC works well and is quiet.
Hope your installation goes well.

Most A/C units are very sensitive to cooling water flow.  Mine is in the forward hanging locker, less than 2 feet from both units.  I have to close the thru hull to ensure I don't air lock the cooling water circuit on a spirited port tack.  A longer hose run may be harder to keep primed.

Good point Ken,

I was planning to put the pump as near to the water supply as I could.
