Why Has My Water Pressure Suddenly Dropped?

Separate a supply-wide issue from a fault at one outlet before replacing taps, pumps or cylinders.

Compare outlets

Check hot and cold at more than one tap and ask whether neighbouring properties are affected. A single weak outlet may have a blocked aerator or local valve issue.

Check safe basics

Confirm the internal stop tap has not been partly closed and look for obvious leakage. Do not operate unfamiliar valves on pressurised hot-water equipment.

Bring in the right specialist

A plumber can measure static pressure and flow, inspect filters and trace internal restrictions. Supply-side issues may need the water company.
