I have two knobs, and one faucet, in my bathroom sink. Both hot and cold slowed to a dribble at the same time. I was brushing my teeth, hot water running, then heard a "pop" sound and the water immediately slowed to a very small stream. I turned it off then on, and tried the cold water, but both seem to have been affected. No other sinks/faucets in the house seem to be affected. We have two sinks and faucets in our master bath...only mine was affected.
Filter screen is clear. And it's not like it slowed gradually over time, but all at once after the pop sound I heard.
