Step 1 · Test Initial Water Pressure
The first critical step is to establish a baseline measurement of your home's current water pressure. First, ensure no water is running anywhere in the house (e.g., toilets, faucets, showers, washing machine). Locate an exterior hose bib (spigot) or an indoor laundry sink faucet. Screw the water pressure gauge onto the faucet's threads, ensuring a snug, hand-tight connection. Open the faucet all the way. The needle on the gauge will immediately display the home's static water pressure in PSI (pounds per square inch). Note this number down. A reading above 75-80 PSI is too high and confirms the need for adjustment.
