Technical or General, I think general? but our sinks were very slow draining, usual comments blocked breather in the grey water tank, valves all gunked up etc etc. I set to and got rid of any bends in the pipe work that held water, i.e. made a valve like an "S" trap and whalla, the water drains with a vortex and a gurgle, all fixed.

This has plagued us with the kitchen sink since the van was new - shower and vanity aren't a problem. I did similar and removed some bends in the sink drain but it hasn't changed anything. I find it helps a lot if we swirl the water quickly in one direction to create a whirlpool effect, then seems to drain much faster.

I increased the size of the pipe going DOWN under sink . I dont think the smaller sink
Plug outlet helps ? Was going to fit an inline (black water) pump ? The extra size down pipe has helped adding extra pressure to pipes outlet .

Last year a lady asked me why her sink was so slow in draining.
A cursory look at the pipework just looked as standard for an Avan Cruiseliner. Then I saw her sullage hose connected to a 12 mm snap on Hose connector and also a short piece of 12 mm hose fitted to the sink outlet under the van. Then the 25 mm sullage pipe. Numerous 12mm snap connections fittings and reducers etc. ???????

Yep, fittings like that would certainly slow it down. It's not the case with ours though.
