Why Is My Water Pressure So Low? Common Causes and Fixes

Weak showers and trickling faucets have a handful of likely culprits. Here's how to diagnose low water pressure.

Low water pressure usually traces back to a handful of causes.

Whole-house: a partly closed valve, a failing pressure regulator, or corroded galvanized pipes. One fixture: a clogged aerator or showerhead, or a bad cartridge.

Sudden whole-house loss can mean a hidden leak or a municipal issue. A pro can measure static pressure and pinpoint the fix.
