I took this video of my faucet. Hopefully it's helpful. [ame]http://www.youtube.com/watch?v=-mgzDZJdoUs[/ame] When I turn on the cold water the faucet won't stay on right away. I have to let it run for a while, I guess to let it build up pressure. This started happening a couple months ago. It doesn't happen with the hot water, only the cold. I checked that the valve is fully on. Any idea how I can fix this?
