Detecting and Troubleshooting Low Water Pressure in a Home

When you’re taking a shower or washing your hands, the last thing you want is to deal with low water pressure. A low water pressure problem can affect every plumbing fixture in your home or one or two in particular. Depending on the location of the problem, there could be multiple causes. Usually, clogged pipes are to blame, but other factors can contribute to low water pressure, such as debris or mineral deposit buildup, a faulty pressure regulator, or damaged water valves or pipes.

Troubleshooting Low Water Pressure Problem

When you have low water pressure in your home, you can try troubleshooting certain areas to see what and where the problem may be:

  • Make sure the shutoff valve near the water meter is fully open.
  • Determine which areas in your home have a water pressure problem; if the problem is in one particular spot, check the affected fixture.
  • Adjust the Pressure Reducing Valve to see if it affects water pressure, which usually affects all of the plumbing in your home.

Whole-House Pressure Problem

  • Your pipes might be clogged with rust or mineral buildup or may have corroded over time; usually, the only way to fix the problem is to replace the pipes.
  • The Pressure Reducing Valve or black flow preventer might have failed, a valve might be partially closed, or you could possibly have low municipal water flow.

Isolated Low Water Pressure

  • If the showerhead is affected, it is most likely clogged and needs removed and cleaned out.
  • Low pressure to the faucet could mean a valve under the sink isn’t fully open, or the faucet aerator has buildup and needs cleaned or replaced.
  • Inspect your water heater if low pressure affects hot water only; check that the shutoff valve near the water heater is open. Have a plumber check for blockages in the lines to your water heater or for other potential problems.
