Starting about a week ago, our kitchen faucet has exhibited some odd behavior. When you lift the handle for it, nothing comes out for a second. You can hear air or water flowing, but nothing comes out. Then, a second later, the water comes out.
If you turn the water off and then on again soon thereafter, it works normally. But if the water is off for awhile, you get the delay again. This happens for hot and cold water. There are no leaks or drips under the sink that I can see.
Our kitchen faucet is the single-handle style, where you move the handle to choose water temperature, and it does have a sprayer attachment, in case that is relevant.
