I shut off the main line to fix the tub faucet. When I turned the main line back on the sink, in the same bathroom, had low water pressure. This wasn't the case prior to the job. It's very cold now so I thought perhaps a water line was frozen, however, every other faucet in the house is running at normal pressure. I tried turning off the main line, opening the sink, and letting it push out any air in the line but that didn't work either. What happened and how do I fix it?

Remove the Aerator try the water see if it works if it does clean the screen in Aerator and install you be OK see the image below, Thanks.

Thanks for pushing that. It worked great. I ignored that idea since there was no problem before I shut off the main. Must have knocked some calcium loose, which got stuck in the aerator. Thanks again.

Thanks for the update and am happy that it worked.
