Within the last 48 hours, two faucets suddenly have really poor hot water pressure. The kitchen faucet has low pressure on hot; on cold it is fine. Right around the corner in the half bath, the hot water pressure is great. Upstairs in the bathroom we have a double sink; one of the hot waters works great; the other one is just a dribble. We have well water, and there is usually a lot of white deposits around the shower head, faucets, etc.

Is this a deposit that has come loose and is clogging my faucets? Thanks
