Some of the supply lines form the angle stop to the faucet have an built in shut off in case the supply line bursts, maybe you have this style and tripped them with an air pocket?

 

Check the aerator screen on the faucet, it may just be plugged from rust and debris from changing the valves. If water came through the faucet and back out the inlet it sounds like its plugged.

 

that is really odd. could be something as stupid as a chunk of the rubber packing from the shutoff valve stuck in faucet. first thing and simpelist is unscrew the faucet arreator off the end of spout and see if water comes out or peices of anything in there. i will assume it is a single handle faucet since it is affecting hot and cold. next thing would be to pull off handle and packing nut and remove the ball or cart and see if anything is there and while its appart turn the water on a little to faucet and see if it come out of the holes were cart sits. if water is ther its a bad ball or cart. or just pull faucet and return it and i hope this helped some and sorry for spelling cant do that worth a crap

 

Single faucet control? Or 2 knobs? My guess is air pocket?.....

 

Nevr mind.... The above sound like the right track

 

Almost every time you turn off the main you'll get a bunch of crap in the aerator on the faucet. When the pressure cycles it seems to knock it all lose from the walls of the piping.

 

It is a 2 handle faucet....forgot to mention that.

I didn't take the aerator off because I only had little more then enough tools with me to change the shut off valves and didn't want to use a pipe wrench on a new fixture if it is that simple, but I really doubt it. There was a very slow trickle of water coming out, but not much. It did not act like something got stuck in the aerator.

 

It may be the aerator then...if you're getting a slow trickle then you are getting water to the faucet...a lot of the aerators have a disc with a hole not much bigger than a pencil lead so it doesn't take much to clog it and as stated above when shutting off the main you always stir up debris.....Good luck and let us know how it turns out...

 

Also, I cant return it. My dumbass already threw the box away.

 

Purchase a new identical faucet, install, put not working faucet in new faucet box and return.

 

I took the aerator off, and there was a small amount of debris. Cleaned it and re-installed, but there was little change. I couldn't waste anymore time on it, so I just bought a new faucet and installed that one. That one works fine.


I did not put the broken one in the new box and try to return it. I'll hold on to it for now, till I either decide to try to fix it or get sick of it taking up space and just pitch it.

 

Could have solder in it from when they made it.

I had a similar incident once and another time I have a ball of solder get lodged in my kitchen faucet and could not turn the cold side water off, must have come from when we replaced the galvanized lined with copper about 10 years earlier.
