A/C drain on Signature 270 question

Recommended Posts

Does the condenser drain go straight to the center bilge on this boat?  Sig 270, 2007. I'm not referring to the constant water flow that goes overboard, I'm talking the water that comes off the condenser itself. My A/C control has a sticker that says make sure the forward bilge breaker is in. I get quite a bit of water there and I have been running the A/C alot. I also have a leaking upper steering pin but that's a separate issue. Ive never had water collect in the center bilge are prior to using the A/C to the extent I am now.

The evaporator is where the condensate accumulates, not the condenser. Find your fan housing and look for the pan unde the e-vap coil. Find it's drain outlet and be sure it's clear. Follow the drain hose from the pan to determine if it exits thru an above the water line fitting or just dumps into the bilge. Some end up in the shower sump which has an auto on pump.  W

I would bet it goes to the sump pump. Most AC unit seat to low, to dump over board.

Agreed, and it would seem his drain hose from the evaporator casing to the sump is plugged. I see them full of mold and it takes a bleach flush to get them clear.  W

For your year model (and because there's a placard reminding you to have the sump pump breaker on), I am almost certain it drains into the shower sump box.  My 2008 does.  It should be under the steps.
