I just ran new copper lines for a small sink, including a water heater.
When I turned on the water a small amount came out of the faucet's cold
tap, under pressure, then no more came. I took off the faucet's filter
before I turned on the water. If I turn off the water, then turn it back
on, the same thing happens.

I checked the filter screen in the pressure regulator and it's clean. Is
there something going on internally in the PR that could be causing this?
As far as I know, there isn't any blockage in the copper lines.

There's nothing else in the system except PR, WH and sink. Oh, there are
taps for a washing machine, but no washing machine.

What's going on?

What did you mess with that has a check valve? Has the sink got a sprayer?
