What Is Causing My Low Water Pressure?


It’s the end of the night and time to wash dishes; you go to turn on the faucet and barely anything comes out. Don’t panic, what you’re experiencing is low water pressure and it affects millions of Americans each year. Luckily for you there are ways to solve this, and identifying what is causing the problem is the first step towards regaining your water pressure and getting those dishes cleaned.

Causes of Low Water Pressure

  • Pipes made of galvanized steel. When water piping in the house is made of galvanized steel, it can rust from the inside out, a similar pattern to when an artery clogs a human heart over time. The result is an imbalance in water pressure. Keep in mind that in homes built before 1970, pipes are a mix of galvanized steel and other similar metal such as copper. This can cause water pressure issues and the only way to resolve this in older homes is to replace the pipes.

If your home is newer and you are experiencing low water pressure always check the pipe coming from the city to your home. You can call the city to determine if they are having water pressure issues. New homes have piping made from plastic or copper so there should never be the same issues you would have with galvanized steel pipes.

  • Cracked and broken pipes. Leaks in pipes, no matter the size, will impact your water pressure. Evaluate whether or not you have a leak by shutting off all water inside and outside your home and then read your meter immediately after, and again two hours after. An increase in water usage likely means there is a leak.
  • Pressure regulators. Water pressure regulators are bell-shaped devices. Typically they are located under your home’s front hose connection. Homeowners usually do not need to adjust these, but it could be the case that the pressure regulator has gone bad. This would require the services of a professional plumber to correctly install a replacement regulator.
  • Mineral deposits. Minerals build up in pipes over time, and the process goes even faster when hot water runs through the pipes. If you believe this is the cause of your water pressure problems, you should call a plumber to evaluate the pipes and determine the necessary repairs.
  • Peak times. Low water pressure could be occurring as a result of the majority of your neighborhood using water at the same time, whether it is for showering or watering the lawn. Consider altering your schedule and pay attention to see if there is a change in your water pressure.

Other Fixes for Low Water Pressure

  • Examine shut-off valves both inside and outside your home. Make sure the valves are turned to the correct position, as this could be impacting your water pressure.
  • Replacing corroded valves will help protect you from future water pressure problems.
  • Examine the specific fixtures that have issues with water pressure. Go to the source to check for clogs and blockages.
  • If you experience sudden problems with your water pressure, there could be pipe work occurring nearby. Ask your utility company about potential projects that could be impacting your water pressure.
