No water pressure in sink. All other faucet's fine. What is the problem?

Hi Oldschool...

Start by unscrewing the aerator out of the end of the spout... probably clogged... ;) Once you have it unscrewed (unscrews counterclockwise) you want to run the water and if water flows well then you will clean the aerator and then reassemble and reinstall. Hopefully that's all there is to it.

Give it a shot and let us know how you make out... OK?
