How to Increase the Water Pressure on a Domestic Water System


To increase water pressure, you must increase the volume available to your system or increase the pressure but at a lower flow. For most domestic situations, increasing volume is not an option and pressure-boosting pumps are used.
Pressure-boost systems may be installed to work with municipal water supplies or your own well water.

Things You'll Need

  • Pressure-boosting pump
  • Pipe and fittings
  • Concrete pump pad
  • 110 VAC or 220 VAC
  • Wood or light metal shelter

Installing Water Pressure-Boosting Pump

  • Shut off your source of water. Either close the water main to your house or turn off your well pump.

  • Mount booster pump on concrete pad or stable ground close to the water source.

  • Separate the water main to your house and remove a segment long enough to accommodate the size of your booster pump system.

  • Connect the water line from your water source to the input of your booster pump.
    Note: the input to the booster pump will include a pressure regulator so incoming pressure does not exceed the capacity of the pump.

  • Connect the output of the booster pump to the water inlet of your house.

  • Connect power to the pump and set up for operation as described in the pump manual.

  • Open water supply from water main or turn well pump on. Check entire line for leaks.

  • Place protective housing over pump system.

Tips & Warnings

  • For ease of future repair and maintenance work, installing cut-off valves before and after the pump will allow you to remove the pump with minimum disruption to your house and well.
