What causes low water pressure?

Common Causes of Low Water Pressure

Low water pressure can be frustrating, making everyday tasks like showering and washing dishes take longer. Common causes include:

  • Municipal supply issues: Sometimes the problem is with your city's water supply, especially during peak usage times.
  • Partially closed main valve: Your home's main water shut-off valve may not be fully open.
  • Clogged aerators: Mineral deposits can block faucet aerators and showerheads.
  • Pressure regulator failure: If your home has a pressure regulator, it may need adjustment or replacement.
  • Hidden leaks: Leaks in your plumbing system can reduce pressure throughout your home.
  • Corroded pipes: Older galvanized pipes often develop internal corrosion that restricts water flow.
  • Clogged water line: Sediment buildup in your main water line can restrict flow.

If low pressure only affects one fixture, the issue is likely isolated to that fixture (clogged aerator or fixture-specific problem). If it affects hot water only, it could be related to your water heater. But if it affects your entire house, it likely requires professional diagnosis. Our plumbers use specialized testing equipment to identify the cause and recommend the most cost-effective solution.
