Why doesnt my bathroom sink drain right?
I never use a liquid plumber, as if it doesn't work, you really need to use gloves as it is acid
Before removing the p-trap, try unscrewing the stopper in the sink... with newer types that is possible. Often, hair and sludge gets trapped under the stopper... try it, if it isn't clogged there, then remove the p-trap.
I had that problem and discovered the drainage had been installed during World War Two using the first prototype of plastic pipe. War years decreased civilian access to metal. It was deformed by soil compaction. The drainage length had to be replaced entirely.
Go underneath the sink and remove the U-bend, you can just screw it off with your hands. Then clean it out. You have a blocked pipe. Just make sure to put a pan underneath as a small amount of water may spill out as you are removing it. Alternativly you could try mr. Muscle sink and drain unblocker, it might work. Good luck
Your problem is likely hair and residue from shaving, makeup removal etc. I have done this very successfully in the past. On the back of the tail piece under the sink is a nut that seals the rod that raises and lowers the stopper. Remove it and the rod then the stopper from above. Take a piece of plastic like a lunch bag and cover the hole and screw the nut back over the hole. Take a washcloth and wet it and place it in the drain hole in the sink. Use the handle from a plunger to hold it there and fill the sink 2/3 of the way with hot water. Remove the washcloth and place the plunger over the drain then place the washcloth over the over flow hole in the sink. Now let some water down the drain and start plunging. It's messy but you should see all kinds of black junk start to come up into the sink. Repeat this process a few times and your sink will drain properly. Obviously you need to reassemble the rod and nut and pop up after.
