If your sink water pressure is low while the nearby shower functions with strong pressure, the restriction is strictly localized to that specific sink fixture. The most common causes include hard water mineral scale (calcium and lime) clogging the removable aerator screen at the tip of the sink spout, a partially closed supply shutoff valve underneath the sink, or a kinked flexible supply hose. Verification: Unscrew the sink aerator and test the water flow; if pressure returns, the aerator was clogged.
