Our galley sink on our SO 37 will not drain.Looks like small hose & tight bend restricts drain flow. Any advise before I start replumbing?

You may want to try to put something small down the drain first to see if you have an obstruction. I would try something like an electritions snake. Ie the thin metal wire uses to fish lines thru conduit. You may want to put some tape on the end if it is not bent or has shart points. so YOu do not hurt the hose. If not, then pulling the current hose, installing a larger one. Or you may find you can cut some off of one end to unbend the current hose to get a clear opening.
How old is the boat? You may have some rust in the valve too. Or it may not be opening.
I also seem to recall someone else mentioning a know problem for SO's too.

I find that a really simple and effective way of getting gunge out of pipes is to use inflatable dinghy bellows. Be warned about blow back though Can be used in either direction, IE from the sink end or in extremis from outside the boat (normally you can reach the skin fitting by leaning over the side of a dinghy, typically will only be 18 inches or so below the water line) to blow the offending item back up the pipe ... but cover the sink to reduce nasty UFOs hitting the headlining!!

Hi, Re:- sinkdrains on S.O.37
I have tried putting an electricians mouse down all my outlets and it has had no effect. There is nothing blocking them as far as I can make out.
I use a rubber drain plunger and after a couple off goes it works perfectly. Until the next time I use the sinks. Even the sink in the heads is very slow running
I wonder if it is a design fault taking the waste water straight into the sea rather than through a vent above the waterline?
Anyone have any thoughts on that?
John

I think there are 2 main reasons they vent below waterline. One is that it is not that pleasant to see grey water discharged from an above waterline fitting. Perhaps more importantly it will only really work on one tack. If the boat is heeled to the side away from the skin fitting it will not drain. Having a fitting as low as possible (IE nearest the centerline) should be a reasonable compromise. On our 34.2 which as 2 sinks I find it drains reasonably well, but I avoid letting the plug out if I have clean dishes drying in the other sink as it tends to vent back unpleasantly Malcolm

I know the problem and i fixed mine on my SO 37. The problem is that an airbubble exists in the outlet tube. This airbubble prevents that the outlet tube fills and that a difference in waterlevel is created. With the airbubble in place the waterlevel in the tube only rises a little bit. When the sink is filled and you pull the plug there is no way for the air to escape from the tube. The airbubble won't travel 50 cm down because of pressure and it cannot go out via the sink because of the water flowing in . If your tube is transparent you can check this with a flashlight shining from the side. The solution is to let the airbubble out . On my boat i made a T connection between the two sinks. The two sinks are now on a single tube. Now the air can go out via the other sink. The remaining outlet tube is sealed. As mentioned in an earlier reply the T connection causes the other sink to fill, only if the waterlevel in your sink is really high. There is also a temporary solution without plumping While flushing the sink put the plug back in. Wait 5 seconds and remove the plug again. Miracle, o miracle it now flushes rapidly. ;D (well, its not really a miracle but real science. By temporarily blocking the flow, the water on top of the airbubble will travel down and increase the waterlevel difference. When you then reopen the sink the water gets sucked in, hence it drains very quickly)

Hi there
I bought a 2006 J45SO and it had a water draining issues as well. This was a factory poor drain line routing issue. The issue was that the drain lines were routed higher than the sink strainer/drain as a result of going over a plywood panel in the galley area. Rerouting both of the lines correctly and at a lower elevation than the sink strainers solved my problem.
Hope this helps Frank

I have a problem with the drainpipe under the sink of my SO 409 (2012): It got blocked just above the seacock after some years of use. It was impossible to clean it with the usual cleaning products so that I had to remove the drainpipe, which is not easy. Have you had the same problem? Any tips for an easier solution would be welcome.

Hi Juanluis,
I don’t know if your water temperature is suitable for swimming, but a kitchen bottle brush from the outside might work for clearing the blockage if it is food scraps.
Air in bubbles seem common in the drain hose and as others have mentioned above, they tend to severely restrict the draining.

I have the same problem with our 2002 SO 37. It is a design problem and the easy fix is simply to continue to use a plunger. We have a small one that I keep under the sink, works well.
