How to Test Your Plumbing for Leaks

Everything you do in your home that involves water depends on your plumbing system. From washing your dishes, to showering, to doing the laundry, you need a certain amount of water pressure to get these jobs done. High water pressure is a common issue in homes that puts stress on a home’s plumbing system. As a home owner, you need to know how to check your water pressure to ensure it is at an acceptable and safe level.


In this post, we’ll guide you through how to do a pressure test on your plumbing system. Once you know how to do this, you’ll feel more confident and save money in the process.


  1. Get a water pressure gauge. Connect this to your house’s outdoor hose bibb/spigot. Make sure there is a washer on the pressure gauge, to connect it just like you would with your normal water hose.
  2. Turn the water on full blast. You should see the gauge start to move. Your water pressure shouldn’t exceed 75 pounds per square inch (PSI). If you find that this is the case, your water pressure Is high and will cause a lot of stress on your pipes and appliances within your home.
  3. To fix high water pressure, add a pressure reducing valve (also called a pressure regulator).
  4. If your water pressure is low (meaning, it is below 30 pounds per square inch/PSI), it could indicate that you have a leak somewhere within your system. It could also be due to build up in the pipes that is blocking optimal water flow.


Checking the health of your pipes and plumbing system is easy to do, as we have mentioned above. However, if you are ever in doubt, you can always call a professional to help you out and conduct a pressure test.
