Sink plug stuck please help

I'm guessing it's stuck down i.e jammed in situ? Try a GOOD plunger to suck it up. If it's super jammed, your only other option is to dismantle the P trap under the sink and manually use a long tool (screwdriver and alike) to push it up from beneath. If you go this route, in theory, the trap can be undone with simple unscrewing of the pipes. Just reverse this action to put back in place. All the best! Glenn

Hot Water First off, you can try hot water. If it is just dirt and grime, hot water is often enough to loosen the debris. Run the hot tap for around 5 minutes and keep trying to move the swivel back and forth every 30 seconds or so. Plunger Yes, the trusty plumber’s plunger. Place your plunger over the plug hole and give it a good working over, hopefully, the suction that it creates will dislodge anything that may be stuck in there causing a nuisance. WD40 If you are still having no joy, I would try a lubricant such as WD40. I would give this a few sprays 1 hour apart trying to get it into all the joints and see if that has had any effect – often, this is highly successful.
