Water pressure

Why is my water pressure low?

Compare the affected fixtures, timing and recent changes before assuming the cause or arranging a repair.

Start with one fixture or the whole property

Low flow at one shower, tap or mixer may have a different cause from low pressure throughout the home. Compare two or three outlets and note whether hot and cold water behave differently.

If you are searching for a low water pressure plumber, record whether the change was sudden, whether it follows a time of day and whether nearby properties have noticed the same thing. The pattern is more useful than a guess about the fault.

Common patterns worth recording

  • One outlet: a blocked aerator, shower fitting, mixer or local valve may need checking.
  • Several outlets: note whether all rooms, only one level or only one side of the property is affected.
  • Hot water only: record the hot-water system type and whether temperature or recovery has changed too.
  • Sudden change: note any water outage, plumbing work, new appliance or visible leak.
  • Intermittent flow: keep a short video or note the time and activity when it happens.

Safe checks around the home

Check accessible isolation valves only if you know what they control and can do so safely. Look for visible leaks under sinks, near the hot-water system or around external pipework. Do not remove mains equipment, alter pressure devices or enter an unsafe roof space.

A visible leak can reduce pressure and needs its own assessment. Read the water leak plumbing page or the guide to a high water bill with no visible leak if water loss is part of the concern.

What a plumber may need to assess

The cause may relate to a fixture, valve, pipework, supply interruption, pressure equipment or a leak. The provider confirms what can be tested safely and whether another utility or authority needs to be involved. A website cannot diagnose the fault from the search phrase alone.

Low pressure is a symptom, not a diagnosis.
The independent provider confirms access, testing, scope, licence, timing and pricing directly with you.
