We are installing a salt water
faucet at the galley
to help preserve our limited fresh water
Iím not a fan of drilling any more holes in the boat than I have to, especially below the waterline
I am therefore considering tapping into the cooling
water line by insering a t-piece just behind the inlet ball valve.
The salt water
pump is a simple manually operated (foot pump) so the draw is negligible, so I am not worried about ďstarvingĒ the supply to the engine
I am concerned, however, that I may introduce a way to suck air into the engine cooling water
(although the engine
is fresh-water cooled via a heat exchanger).
If I put a ball valve in the line to the pump, will the system be ok, or am I taking too much of a risk tapping off the engine cooling water
Thanks for your advice.
