The pressure level can vary, but 60 PSI (pounds per square inch) is recommended for most residential homes. Water pressure should not be higher than 80 PSI. Anything higher can cause major appliances, including water heaters and toilets, to stop working properly because of the stress on plumbing and other parts.
Normal psi for a home pipe system is between 30 and 80 psi. While you don't want the psi to be too low, it violates code to be above 80. Instead, you should aim for a psi that's between 60 and 70.
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.
So What Is The Ideal Home Water Pressure? As previously mentioned, the normal water pressure should register between 40 and 80 psi (pounds per square inch), with the recommended home water pressure being around 60 psi. Anything in between is considered good water pressure to have in your home.
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.
Is your water pressure too high? Most plumbing fixtures are designed to handle a maximum water pressure of 80 psi or lower. If your water pressure is higher than that, it can potentially cause the parts for your faucets, water heater, toilets, and shut-off valves to fail.
The ideal water pressure for a house will be somewhere in the range of about 45 to 65 psi. Anything higher than 80 psi can cause damage, and anything much lower than 45 psi may result in issues when you use your shower, toilet, dishwasher and other water-consuming appliances.
High water pressure puts excess strain on your plumbing system, including your pipes, seals and appliances that use water. As high volumes of water are forced through, the parts that make up your plumbing system are stressed by the pressure which can lead to a variety of problems.
The ideal pressure for the health of your plumbing system and appliances is between 40 and 60 PSI, and building codes in most areas specify that water pressure is under 80. If yours measures over 80 PSI on the gauge, it is definitely time to lower the pressure.
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.
A quick and easy way to increase water pressure is to adjust the pressure-reducing valve, which can be found in your home, usually close to your water meter.
Another way to increase GPM is to turn up the water pressure. This can be done by adjusting the pressure valve on your pressure washer. Be sure not to increase the pressure too much, as this could damage the machine.
The maximum recommended water pressure for homes is 80 psi; any pressurization exceeding this amount will result in thousands of wasted gallons of water each month.
(Normal is 60 psi and very few areas are below 40 psi) The pressure of the streams will drop under these extreme conditions, of course, but the stream integrity is preserved. This photo shows the stream integrity of our Perfect shower head (old style).
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. Remember to make small adjustments at a time and continually check the pressure for accurate and safe results.
While true gravity tank toilets will operate at water pressures of only 10 - 15 psi, pressure- assist tank and flushometer toilets usually require 25 - 40 psi and, sometimes, even more. This is the pressure at the toilet, not the pressure coming into the building.
Your area's water needs may have changed, causing the increase in pressure. Your water pressure regulator may be broken. They're designed to control the water pressure in individual houses, but just like any piece of equipment it won't last forever.
Shower Heads - The optimal water pressure for a shower head is between 40-60 PSI. Below 40 PSI the flow of water may be weak and unsatisfying, while over 60 PSI it may be uncomfortable or even painful.
Find the spigot closest to your source of water. Make sure all the taps and other water uses are turned off in your house. Now turn on the spigot and see how long it takes to fill the bucket. Dividing the number 60 by the time to fill the bucket will give you the gallons per minute number.
For instance, if 35 psi is recommended, and the maximum safe pressure listed on your sidewall is 44 psi, you can safely put 38 or 40 psi in your tires. You can even go to 44 psi. You'll experience a harder ride, but you won't create a blowout danger. You may even experience sharper cornering and increased fuel economy.
Water pressure regulator replacement: $250 to $1,000. Pipe section replacement: $500 to $4,000.
When water pressure runs in excess for too long, it can cause your toilet's fill valve to break more quickly than expected. A broken fill valve might result in your toilet flushing on its own or even running when you're not using it.
50' x 40 psi = 80 psi (for 100 feet)
Entering Chart No. 1 at 80 psi, move vertically to the 5/8” diameter line, left to the flow rate scale, and read 16 gallons per minute (approximate).
Water pressure over 80 psi can cause damage to your home's plumbing fixtures, including anything with a rubber gasket. Common problem areas include: water heaters.
