If only a single faucet in your home is suffering from low water pressure while all other taps function normally, the issue is localized to that fixture. The most common causes include mineral scale (calcium and lime) clogging the removable aerator screen at the tip of the spout, a partially closed supply shutoff valve underneath the sink, or a kinked flexible supply line hose. Verification: Unscrew the spout aerator and test water flow; if pressure returns, the aerator was clogged with sediment.
