Redirecting Hunter 49 A/C unit drain pan water (condensation) away from bilge

My only obstacle from a completely dry bilge seems to be water condensation building up in A/C unit (3) pans and draining passively into the main bilge. This has been the set up since owning my 49 and assume that is the way the system is set up from factory. Has anyone developed a set up to hook up small drain hoses to the hole bib on each A/C pan and then run into a dedicated sump, or, perhaps a way to connect to one of the vanity drains that passively exits a thru-hull below water line? When aboard and using the A/C, within a few hours, the dry bilge starts to build up water (fresh) and it would be great to divert that drain pan water overboard directly without entering the bilge first.
Thank you for any suggestions!

Do a search on the forum for Venturi installation. There was a post sometime back that addressed this. I installed a Venturi to move condensate overboard with discharge and fixed bilge condensate problem.

This is the simplist and best solution to eliminate condensate water. You can buy a $100+ Venturi tube marketed for this purpose or better obtain one from a water bed store or big box hardware store for less than $20 which will suck condensate out with the AC pump so there is no need for more plumbing or separate sump.

Hunter 420 Passage San Diego
For what it is worth, on my 420 Passage, I put a nipple in the line and ran some extra hose to one of the spare punch outs in the sump pump that is right behind the bilge on my boat. Under 50 bucks. Just a thought. Sorry I dont have a pic.

Great suggestions above plus you might refer to these two threads to address your question:

Air Conditioner condensate drain

I would appreciate some advice on how to best handle air conditioner condensate that is presently flowing into my bilge. The previous owner of the boat had a marine contractor install a Cruisair emarld series reverse cycle heat pump on the boat. It consists of a condenser mounted under the...

Air Conditioning Drain Pan

Hello All: I have a 33' sloop. I have an air conditioning unit under the starboard lazarette. The thing really works great but whoever installed it didn't install a drip pan or anything under the unit. So water just drips its way over some plywood and wends its way donw into the bilge. Can...
