Hi, about a month ago I had a new faucet installed in the backyard. To do this, I turned the main house water off. When I turned it back on, no water flowed from the bathroom sink. This happened once before and it finally came back on, but it's been a month and no water. I turned the water off again and left this faucet ON, but that didn't do the trick. I'm really getting tired of washing my hands in the bathtub! :) Any ideas? Thanks!!

When you say no water do you mean no hot, no cold or NO water?
What type of faucet do you have at the bathroom sink, one handle or two? Brand?

Did you nremove the aerator,(see image) and check and clean the screens?
Try the faucet with the aerator off. Can youn get water? Let me know, Tom
