Low water pressure in showerSan Jose, California

A shower that has gone from a strong spray to a weak trickle makes daily routines frustrating and may signal a bigger plumbing issue. If only one fixture is affected, the cause is usually a clogged showerhead, a partially closed shut-off valve, or a failing cartridge in the mixing valve. If multiple fixtures are weak, the problem may be corroded galvanized pipes restricting flow, a failing pressure-reducing valve at the main, or a water heater issue limiting hot-side flow. A licensed plumber can isolate the cause, clean or replace the affected components, and restore full pressure.
