Residential water pressure tends to range between 45 and 80 psi (pounds per square inch). Anything below 40 psi is considered low and anything below 30 psi is considered too low; the minimum pressure required by code is 20 psi . Pressures above 80 psi are too high.
The ideal water pressure level is between 50-70 PSI.
If your water pressure goes above 70 PSI (even occasionally), you should install a pressure regulator to your main water line.
Normal water pressure is generally between 40 and 60 PSI. Most homeowners prefer something right in the middle around 50 PSI. Once you measure the water pressure in your house, you can adjust it to a setting that is ideal for all family members and household uses.
Anything over 80 psi is considered too high and could damage your plumbing system. On the other end of the spectrum, anything below 40 psi is considered low pressure, and anything below 30 psi is considered too low.
Indoor water pressure typically falls between 45 and 65 psi, considered safe and efficient for any household plumbing system. Maintaining water pressure within this recommended range helps safeguard against potential damage to pipes, fixtures, and appliances.
Most residential plumbing systems are designed to handle 40 to 60 PSI of pressure, with 80 PSI being the typical maximum and anything over 100 PSI being possibly detrimental to plumbing components.
Over time, high water pressure wears on your plumbing system and leads to: Leaking Pipes: High water pressure continuously puts too much force on your pipes. Eventually, your home's pipes will likely wear down until they can no longer hold back the water.
The higher the psi, the more force the water is putting on your pipes. The ideal water pressure range for most homes is between 60 and 70 psi. If your water pressure is 80 psi or higher, you're likely going to run into some serious plumbing problems.
- Generally installed in your kitchen near where the cold mains water enters your property. - Water pressure will typically be between 1-2 bar.
Pressures above 80 psi are too high. Whereas low water pressure is more of a nuisance than a serious problem (some fixtures, like washing machines, have minimum pressure requirements), high water pressure carries with it a significantly increased risk of damage to pipes, joints, fixtures and seals.
While 50 to 70 pounds per square inch (psi) is the ideal range, most plumbing fixtures are designed to work with water pressure up to 75 psi. Anything higher than this can damage your pipes and fixtures.
If your pressure is higher or lower, then you'll need to install, repair, or adjust your pressure regulator to comply. Adjusting your regulator is easy, as long as it's working properly. Simply tighten the screw down clockwise to increase pressure and counter-clockwise to decrease pressure.
The Mechanics of Flushing
The standard toilet relies on gravity and water pressure from the tank to flush away the water in the bowl. Unfortunately, this pressure can weaken with natural wear and tear. If your toilet lacks sufficient water pressure when flushing, you've come to the right place!
Normal water pressure range
In general, residential water pressure ranges between 45-80 psi (pounds per square inch). If your water pressure is under 40 psi, it's considered low.
The pressure level can vary, but 60 PSI (pounds per square inch) is recommended for most residential homes. Water pressure should be no higher than 80 PSI. Anything higher can cause major appliances, including water heaters and toilets, to stop working correctly because it stresses plumbing and other parts.
Anything exceeding the normal range (60, 70, or even 80 PSI) can cause significant problems with your home plumbing system, making it more susceptible to leaks, water hammering, pipe bursts, and problems with your fixtures.
You can increase water pressure from your home's well by adjusting the pump's pressure switch to a higher psi — but be careful not to turn it too high. Increasing your well pump's pressure beyond 60 psi can potentially cause broken pipes and switch failure.
Locate the PRV, usually near the main water shut-off valve. Look for an adjustment screw on top of the valve. To increase pressure, turn the screw clockwise. Make small adjustments and retest the pressure after each turn.
If, on the other hand, your home's water pressure is high, this can cause many problems such as burst pipes, leaks, or rattling pipes. These issues are likely to increase the amount of water your family is using, which will affect your water bill.
80 psi – Prolonged pressure above these levels may damage appliances. (Recommended) 90 psi – Max rating for most whole-home filtration systems.
If you tighten the screw the water pressure will be more and if you loosen the screw the water pressure will be less. Turn the screw clockwise to tighten it and increase the pressure, or turn it counterclockwise to decrease the pressure. Do not be too hasty.
No, and in some cases, you may not need one. Certain municipal supplies regulate their water pressure safely, but if that pressure runs above 80 psi, you'll want to protect your plumbing system by installing one.
Reducing water pressure by partially closing a valve is not recommended as it can cause damage to the valve and the plumbing system. Instead, adjusting the water pressure should be done using a pressure reducing valve, which is specifically designed to manage the pressure safely and efficiently.
