I don’t recommend sharing the Engine
Raw Water intake with anything. Watch your Engine Temperatures carefully!
1. It’s possible that the
Watermaker could draw down the Engine’s
Cooling Water Pump, leaving a vacuum in the
pump.
2. The best time to make water, is when the Engine (& Alternator) are running, something you NEVER want to do with a shared intake - it could starve the Engine of vital
Cooling Water.
I recommend you install a dedicated water supply intake to the
watermaker, ASAP.
FWIW,
