48 sundancer Air Conditioner drainage

[Benestee]

My salon Air Conditioner drain pan is full of water. It doesn't seem to drain well. I know it supposed to drain into the sump under the salon floor but it doesn't do it well.
I have standing water aft under the salon floor. I think some of it is from the "gray water sump" which splashes out when running the boat, but also might be runoff from the ac unit.
The salon and aft ac are t off to drain together into the sump. Has anyone else had issues with this.

I had this issue in my 360 da and it turned out to be junk in the pan drain, Not sure this is your issue or not. I used a long plastic zip tie to clean out the junk. BTW it happened twice but both times it was junk in the drain hole of the pan.

I had a similar issue. The plastic knockout in the pan where the hose is connected was not fully knocked out. That plus crap buildup caused the pan to not drain which caused the squirrel cage to run in in the backed up water which caused the blower motor to fail which caused so much corrosion that I just put in a new AC unit.
