Question for the experts…do I need to worry that both aft and forward a/c discharge ports are shooting out water when only one a/c is running? Doesn’t matter if forward or aft is running, both holes are shooting out the discharge water.

Thank you
 
There is only one A/C raw water circulation pump - it supplies water to both A/C units. You will see a discharge from both ports no matter how many units you are running.

Ok thanks. I knew there was only one pump that fed both units, I just assumed there were some sort of check valve or something to only cycle water through when that unit was on.
 
My 31cb AC discharges water from 2 ports— when either a single air con is running - or both air con’s are running.

Re the 2 water discharges - one port has a stronger stream than the other - at all times.

Thank you for that!
