Turn off all taps, showers, and water-using appliances
Find an outdoor hose bib or a faucet with a threaded spout
Attach a water pressure gauge to the faucet
Make sure the gauge is tightened securely by hand
Open the faucet fully
Read the pressure shown on the gauge
Record the reading in pounds per square inch (PSI)
Check multiple faucets if needed for comparison
Test at different times of day if pressure seems inconsistent
Compare the reading to the normal home water pressure range of 40 to 60 PSI
Turn off the faucet and remove the gauge after testing
