If your tap water suddenly runs slow, something is probably blocking its flow.1) Check the supply valves under the sink—be sure they're fully open.2) Unscrew the aerator on the end of the spout, if there is one, and clean it out thoroughly with hot water and an old toothbrush. 3) If these measures don't work, shut off the water to the faucet and disassemble the faucet to check for debris or a dislodged faucet washer.
