Kitchen Sink Water Flow Problem

[Art-n-Marge]

We get that too. I figured it was low pressure water. It happens with the lavatory or the sink, the hot or cold taps, just kind of arbitrary. We'll let it run for a little while, get irritated about the poor flow, then shut it off, yell and scream at each other to curse at it for a few seconds, then turn it back on and it works better. We always thought it was the yelling and screaming improved the pressure.

While I wonder if it's a pressure equalization problem not a vapor lock (air doesn't seem to be present in our case), I suppose a more logical explanation and solution would be better. But different from your problem we always seem to have some amount of water flow.
