Nothing like the high-humidity early start of summer in FL to show you the flaws in your AC systems...
I found it 'raining' in the engine room the other day as the salon AC condensate drain was not doing its job, and the water was running down into the ER. I used a garden hose connected to hot water to flush the line but it was never clogged. Still was not draining the way it should, so I took a closer look at how it was routed.
PO had attached the hose to the ER ceiling for a run of about 8 feet, then down the aft bulkhead to the overboard fitting which is above the water line. A few small 'dips' in the hose plus some unnecessary unions meant that the gravity flow of water just couldn't get through the way it should. Very little slope, if any, overall for that 8 foot run. I rerouted the hose to give it some slope and remove the low spots. It's working much better. However, the drain pan does not stay as dry as I'd like nor does it stay as dry as the other systems aboard.
I am thinking about venting the condensate line to put some "air behind water" as is common in household systems. I wonder if adding a simple standpipe about 3" tall at the AC drain pan connection would help? I've never seen this on any boat we've owned but wonder why / why not...
