If your Plumbing Check results look unusual, the most common cause is that the water to your home was not fully shut off during the test.
For a Plumbing Check to work correctly, the main water shutoff valve must be completely closed. If the valve is only partially closed, small amounts of water can continue flowing, causing pressure fluctuations that appear irregular in the app.
What To Do
Make sure your main water shutoff valve is fully closed.
Confirm that no water is running anywhere in the home.
Run the Plumbing Check again.
When the water is fully shut off, the pressure should remain stable during the test unless a leak is present.
If your results still appear unusual after confirming the valve is fully closed, you may want to inspect the shutoff valve to ensure it is functioning properly.
