Yes, just expanding on why that is the case.

I think it might be easier to fit a new outlet in a better position, with less elbows and better fall, assuming it can be above the W/L, then just leave the stopcock where it is. Deal with it next lift out. Or not, as it suits you.

When I first launched my boat I had the same issue with the gally and aft sink draining with the skin fitting and seacock out the side of the boat.
At my first beaching I replaced the side skin fitting with a skin fitting directly below each sink outlet passing through the batton of the boat with a stainless steel pipe up to just below the sink drain and positioned the sea cock just below the sink outlet, Problem solved and complied with all the regulations.

So is rice and, especially, fatty residue from breakfast frying pans. A periodic pumping with a plunger as used for clearing domestic sink drains also helps; that's what they are meant for after all.

I don't have a plunger, bit i've found two methods with my fore finger. If it's going slowly i stick my finger in the plug hole, wait a few seconds and pull it out, the water must seep away while my finger is in the plug hole, then the sudden inrush gets it all going again. If it stalls i find rapidly pushing my finger in and out of the plug hole shifts it, it's only a small hole so my finger is acting like your plunger.

Paul I has a real giggle wondering what you were describing !!!
May be you need to clarify.
" i've found two methods with my fore finger. If it's going slowly i stick my finger in the plug hole "
" If it stalls i find rapidly pushing my finger in and out of the plug hole "
Whom sail one track mind.

Thank you all so much for shedding some light and a lot of insight into the issue I am having.
My gut feeling is that the situation would be improved with a re-routing to the existing seacock. The route taken by the pipe is vertically down and then has two 90-degree bends between which the flow has zero gradient hence my assumprtion that the slow rate of drainage could be improved if these are eliminated. However, I think I should bow to all of your experince and accept that it may not be possoble to improve anything unless I re-site the seacock.
So I guess its PaulRainbows' forefinger solution for now... well not literally his forefinger but you I guess you know what I am saying.
p.s moderator we are describing something all perfectly above board

Parts of this thread remind me of that ( very ) old Boy Scouts' campfire song.... from a very different age....
"I stuck my finger in the woodpecker's hole and the woodpecker said 'God bless my soul! Take it out, take it out, take it out..... Reee-move it!'...."

You might get a slight improvement by replacing the elbow with a hose tail, then just a hose from there to the plughole. If nothing else it might make it less prone to blockages.

Possibly, but I suspect it's maybe the horizontal section where deposits are going to occur. All depends what he washes down the plughole! Occasionally pouring a kettle of boiling water down might help deter build-up.

These methods are not for everyday use Roger, just for when you get a blockage
A blockage where ?
I was also intrigued buy the sticking your finger in when it (she) stalls.

No grease goes down and yes I occasionally pour boiling water down and agitate with a plunger. Although initially it helps after washing up a few times it goes back to normal. Perhaps debris is settling in the horizontal section?

That sounds plausible. Probably impossible to avoid some grease even if it only comes from the washing up. The flow from my galley sinks was slow until I replaced the hose this spring. It would take minutes for a full sink to drain into the other sink with the seacock closed, so the worst bit was between the two sinks. Not exactly an expensive job to replace the hose and see what improvement there is.

I've only used it on my galley sink, but i guess it would work on most waste blockages Roger.

I agree, hence my suggestion of removing the elbow. If the elbow was removed and the hose tail screwed straight into the valve, the hose could be re-routed to go more or less straight to the sink waste.
pvb

Maybe better, but from what the OP has said there may still be a section of pipe which is more or less horizontal.
PaulRainbow
Well-Known Member
That'll be the bit that goes to the elbow, as in post #14. Removing the elbow and re-routing the pipe to sweep from the plug to the valve gets rid of it and may help.

The hose looks to be a fairly small diameter. Would it help, by preventing airlocks, if a larger size could be used? Feasibility my depend on the sink drain fitting.
