: The hot water pressure on my laundry sink (about 15 ft. from the hot water heater) doesn't get constant water pressure, but it follows a distinct pattern. When you first turn on the hot water, it comes out fine, but after about 10 seconds (when the water is starting to warm up), it immediately slows to about 1/4 of the original flow and doesn't increase no matter how much you turn the handle. If I turn on the cold, I get plently of pressure.

: Any idea what might cause this?

John,
I would pull apart the hot side of the faucet and inspect.
