Information For Proper Water Pressure In Your Home





Often municipal water supply pressure can run quite high, say over 80 psi and in some communities, more than 150 psi.


Most plumbing fixture manufacturers recommend their products be used with water pressure no higher than 80 psi. Anything higher than that can cause fixtures such as water heaters, faucets, shut-off valves and toilet parts to fail prematurely.


If the building water pressure gauge reading is ever found at 80 psi or higher, you will want to install a water pressure regulator at the point where water supply enters the building, or at the meter.


Most homes contain a water pressure regulator. This device regulates how much pressure water is allowed to enter a home with. The regulator sits along the main water line, usually in an access panel, crawl space or basement. The regulator has a gauge on the top of the valve that points to how much pressure is coming through the pipe. Adjust the valve by loosening the locking nut around the bottom of the valve and turning the screw on top of the gauge to the desired psi rating. Tighten the locking nut again when finished.


The normal range of water pressure in a residential application is between 40 psi and 80 psi. There is no specific rule about how much pressure is best for your house, since everyone’s needs are different. However, anything below 40 psi will likely lead to poor performance of devices that use water. Anything higher than 80 psi could lead to damage, such as blown sprinkler heads or ruptured pipes. Check your pressure regularly by attaching a pressure gauge to an outdoor faucet and turning on the water.


Obtaining and maintaining the desired pressure in your home is the responsibility of the Certificate holder. This can be accomplished by hiring a licensed professional.
