Low Pressure after turning off supply?
Hi, I see there are a lot of low water pressure questions here, sorry to add to the list! 
I was contemplating putting in our new bathroom faucet yesterday and shut off the supply at the sink, then realized I didn't have the time and left the job for another day. I forgot to turn the supply back on until several hours later and when I did, the water supply was very low. With the water running, I have turned the valves on and off and while there is an even further decrease in pressure when the valve is shut off, it does not completely shut off the water supply.
All I did was turn those stupid knobs and now I feel like I have a large problem on my hands...can anyone help?
Thank you very much!
P.S. If only I would have followed the sage, time-tested advice of checking that ridiculous aerator (sp?). I thought that due to the coincidence of turning off the water/low water pressure that there had to be some large problem looming out there, but alas, it was just the aerator. Thanks for the great forum. Perhaps one day I will ask a question that hasn't been answered!

myersgirl, Welcome to the DIY Forums.
If the aerator being plugged was the problem, the shutoff valve is probably doing the same thing. Simple fix though. Turn the water off at the valve (depending on how much water still seeps through) If it is too much, you will have to turn off at the main. May take two people if you need to shut off at main. Disconnect the supply tube at the valve and turn the water on and off 3 or 4 times with a rag over the valve. This should clear out any debris that is blocking the valve from shutting off. Good luck.

Dragon could be correct but there may be another problem if that doesn't work. Over the years I've run into the problem that sometimes the washer in the shut-off valve deteriorates and will break and lodge in the valve. You then have to shut off the water to the house and either try to replace the washer in the shut-off valve or just replace the valve.
