Replaced faucet "ball" 12 months ago. Worked fine. Recently, no water flowing from kitchen faucet nor is adequate/any water flowing to dishwasher. One afternoon hot water only flowed with normal pressure from faucet, but has since stopped. Very small trickle of water from from sink sprayer, but has since stopped as well. All other faucets/shower function normally. Suggestions where to look/what to do?
