Hi, I’m winterizing my three AC/Heater units for the first time, so I need some advice. I know how to feed the antifreeze up through the raw water strainer, so I’m good there. Here’s my question:
Normally, when I turn on the pump relay and any one of the AC/Heater units, water comes out three separate through-hulls. Does this mean that when I feed the antifreeze into the raw water strainer I only need to turn on one AC/Heater unit to flush antifreeze to all three units, or do I have to turn on all three AC/Heater units to make sure antifreeze gets to the water systems on all three units?
