bathroom sink

Check for junk in the faucet.

Remove the aerator. It may be clogged with debris.

I would take it that its hot and cold not working?

The hot water heater has to fill up first. According to whether its a 6 or 10 gallon it will take a while, then water should flow freely. Just a maybe !!

I just de-winterized fifthwheel. I opened kitchen sink air came out then water, shower same, toliet same, then bathroom sink same, except water suddenly stopped and some more air then nothing. Now no air or water comes out of bathroom sink, can't find any leaks. Is there such a thing as an air lock preventing water to flow to sink. I am hooked up to shore water.

Take the aireater off the faucet and clean the screen.
There is most likely Stuff in the screen. And yes it will prevent any water from coming out!

I had a new pump put in and when I turned on the faucets NONE of them worked!!! Right away everyone was pointing to the installation. Turned out every faucet screen and been plugged with real small particles of sugar sand.

Yup it filled up every hole in that tiny screen and stopped the water completely.

Bingo, it was the aerator, just one tiny piece of sand or dirt that totally blocked the water, thanks.
