I donít recommend sharing the Engine Raw Water
intake with anything. Watch your Engine Temperatures carefully!
1. Itís possible that the Watermaker
could draw down the Engineís 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
I recommend you install a dedicated water supply intake to the watermaker
