Low water pressure in shower — San Francisco, 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.
Waarom dit veel voorkomt in San Francisco
San Francisco's Victorian and Edwardian housing stock hides original galvanized and cast-iron pipes long past their service life, prone to corrosion and low pressure. Hilly terrain complicates drainage, and seismic shifting periodically cracks pipe joints and sewer laterals.
