The sink is new (45cm diameter round) and worked fine on day 1. Now however (day 2) it has decided to drain really slowly - like it is blocked. I have taken the u-bend and pipes apart and there is no blockage. The only think I can think of is that there is a blockage in the pipe further down the line (in the wall) - if so maybe a plunger will work.
Was the drainline for this sink disconnected for a few days or weeks? If so, anything that was clinging to the inside of the pipes may have dried out and fallen into the main part of the line causing a blockage. You may need to snake the line out.
If you have never made a mistake, you haven't done much.
My solution has always been to try a good enzyme-based drain cleaner first, such as DrainCare, NOT a caustic-based such as Drano.
It won't harm the sink or fixtures, but it WILL eat out all organic clogs(grease, food particles, etc.) that get built up in a kitchen drain line.
Run warm water down the drain, pour in the drain cleaner as directed, allow to eat overnight, and then flush with very hot water the next a.m.
I use a kettle of boiling water the next morning to first get it going and then follow that with the hot water-only faucet until it runs clear.
EDIT: Never pour grease or oils down a sink. Clean out pots, pans and skillets into the trash of greasy matter. Those are the worst cause of clogging.
EDIT: Aha. There is that majakdragon grasshoppa again! LOL
