After washing my 30+ this weekend I discovered my port cockpit drain is not draining or flowing properly. This drain connects to a T at the thru hull which is shared by the galley sink. The galley sink is draining without issue, and if I close the thru hull, and blast water in there the sink will fill.
I cleaned out the drain with a snake, stuck a high pressure hose in there and also poured a lot of hot water down the galley drain. Still there is water at deck level of the drain. This drain used to work fine, so it makes me think it is blocked, but after seeing water flow into the sink I'm not so sure. The starboard drain is fine (and does not share a thru hull.) The cockpit drain is the highest point, above the sink. Perhaps there is a slight restriction, and because there is no vent to atmosphere above the drain it won't flow? I'm unsure.
I'm pretty sure the drain is not clogged at this point (and removing the T to access would be very challenging.)
