How to Even Out Water Pressure Fluctuations


Water travels through your plumbing system and out your sinks and showers due to pressure. For the fixtures and appliances in your home to function properly, this pressure must be kept in a constant range. If the pressure becomes to high, pipes in your home can burst. If the pressure falls too low, it may not be enough to supply all of your fixtures and appliances, especially if more than one is being used at a time. With a few simple steps, you can check to ensure that your water pressure is within the acceptable range and adjust it based on the effects that you experience.

Things You'll Need

  • Water pressure gauge
  • Pipe wrench
  • Drain cleaner
  • Locate your house's bladder tank. It is usually a blue tank in your basement, crawl space or right outside your house where your utility boxes are located.

  • Read the pressure gauge on the blue tank.

  • Connect the water pressure gauge to an outside faucet closest to your water source.

  • Read the gauge. The normal range for proper functionality should be between 45 and 80 psi. A higher reading can lead to damage of the plumbing in your home. If your pressure is within the normal range, continue on to the following steps. If it is above or below the normal range, stop right here and contact your water company as the problem isn't within your home; it's related to the water main connected to your home.

  • Locate your home's main water supply control. The valve is usually in the basement or utility space.

  • Ensure that the valve is turned to the completely open position.

  • Use drain cleaner in each of the pipes that have low water pressure to ensure that no calcium deposits are blocking the water flow.

Tips & Warnings

  • If this does not correct the problem, then the culprit is your plumbing system.
  • Galvanized tubing rusts over time, thus clogging the line and preventing the proper flow of water throughout the home. If none of these steps fix your problem, then you may need to call in a plumber to replace your existing pipes.
