Results for “how to adjust water pressure in house” · retrieved September 22, 2026
You can adjust your home's water pressure by using a pressure gauge to verify your current PSI and then turning the adjustment bolt on your pressure regulator valve (PRV).
To adjust water pressure, first measure your current pressure using a hose-bib gauge attached to an outdoor faucet; the ideal range is 40 to 60 PSI. If you have a PRV (a bell-shaped brass device on your main water line), you can adjust it by loosening the locknut and turning the adjustment bolt clockwise to increase pressure or counterclockwise to decrease it. Make only small, quarter-turn adjustments and re-test with your gauge after each turn. If your pressure is already within the safe range or if the PRV is damaged, do not adjust it. Other common causes of low pressure, such as partially closed valves or clogged aerators, should be ruled out before adjusting the regulator.
Answer details
Measure your current pressure first
Attach a water pressure gauge to an outdoor hose bib or laundry faucet to establish a baseline. Normal residential pressure is typically between 40 and 60 PSI; readings above 80 PSI can damage pipes and appliances.
Adjust the pressure regulator valve
Locate the bell-shaped PRV on your main water line. Loosen the locknut with a wrench, then turn the adjustment bolt clockwise to increase pressure or counterclockwise to decrease it. Make small, quarter-turn adjustments and re-test after each one.
Check for other common causes first
Before adjusting the PRV, ensure your main shutoff valve is fully open and check for clogged faucet aerators or showerheads, as these are common causes of low pressure that do not require regulator adjustments.
Secure the setting and know when to call a pro
Once the desired pressure is reached, tighten the locknut to secure the setting. If the adjustment bolt is seized, do not force it, as this can damage the internal diaphragm; contact a professional instead.
