What Causes Low Water Pressure in a Home?

Low water pressure can be caused by supply limitations, pipe corrosion, leaks, clogged fixtures, or failing plumbing components.

Common Causes of Low Water Pressure

Low water pressure isn’t always caused by the same issue. In many homes, it’s the result of multiple factors affecting how water flows through the system.

  • Municipal supply limitations: Low pressure coming into the home
  • Pipe corrosion or buildup: Restricts flow over time
  • Leaks: Reduce available pressure throughout the system
  • Faulty valves: Including partially closed or failing shutoff valves
  • Pressure regulator issues: A failing PRV can cause inconsistent pressure
