Step 1

Test your Water Pressure

  • Hook up the pressure gauge to an outside water spigot.
  • Turn on the water.
  • Read the instant reading.
    • Make sure the shutoff valves near the water meter are fully open.
    • If the reading is low, the city may be delivering water at a low pressure (less than 40 psi)
    • If your house is on city water, ask your local water department for a pressure reading.
  • A reading of 45 to 55 psi is ideal.

Pressure Booster

  • If your water department can’t deliver more pressure and you have a 3/4-in. or bigger copper or plastic water main coming into your house, consider installing a water pressure booster.
  • Water pressure boosters like the one shown here are available at home centers and online for about $900.
