Morgan OI 30 has two drains in at the aft end of the cockpit. My starboard drain does not flow, although port one is OK. I'd feel more comfortable sailing with both sides working. Both drains are plumbed together to the single overboard port in the stern. Is it possible one side is just plugged with crud (tree trash, berries from bird poop, etc) or is there some sort of check-valve in the downstream plumbing before the lines join together? I haven't tried going over the side to give the line an enema, but that is a choice. Any knowledge will be appreciated.
