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.
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.
Maintaining water pressure between 40–60 psi is recommended for well water systems. It's important to periodically test the water pressure to ensure it falls within this range and detect any issues early on.
What Happens if Your Water Pressure Is Too High? Water streaming through your pipes at high pressure can damage the integrity of your pipes, leading them to erode more quickly. High water pressure can even instantly destroy pipes in your house.
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. A psi between 20-30 is considered very low, and under the minimum water pressure required by most building codes.
The ideal water pressure level is between 50-70 PSI.
This will protect your plumbing and appliances, saving you from both the unexpected plumbing accidents and saving you money on your water bills and appliances.
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. Call a Seattle plumber right away if you spot any of these signs of high water pressure in your house.
High Water Bills: Physical problems aren't the only issues caused by high water pressure. If your pressure is too high, you could also see an increase in your water bills. If you're trying to save money on utilities, high water pressure could be costing you.
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 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.
Ideal water pressure for homes is 50-70 psi, 60 is the sweet spot. Low water pressure can be caused by clogged pipes, leaks or closed shut off valves, high pressure can damage your plumbing and appliances.
The ideal well water pressure is between 40-60 psi. If you're uncertain whether your water pressure falls within this range, learn how to test your water pressure. It's a good skill to learn. Checking your water pressure a few times a year can help you detect problems before they get worse.
Good water pressure is somewhere in the neighborhood of between 40 and 55 PSI. 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.
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.
Banging or Clanging Noises in Pipes
This is a sign that the pressure in your pipes is already extremely high, and the shuddering is your pipes adapting to the pressure increasing when you turn off the water. This also means that you could find yourself dealing with plumbing leaks within a short period of time.
If your water usage is unchanged, your city hasn't implemented a rate hike, and you have a high water bill with no visible leaks, the problem may be that you have an issue with your water meter. This isn't a common problem, but it's also not unheard of. To test your water meter, turn off your water.
Constant exposure to high-pressure water can dry out your scalp, leading to irritation and inflammation. This kind of environment is not conducive to healthy hair growth. The scalp may become dry and flaky, leading to conditions such as dandruff.
On average, approximately 70 percent of that water is used indoors, with the bathroom being the largest consumer (a toilet alone can use 27 percent!).
Water Pressure Readings
A water pressure reading will tell you exactly how forceful your water is in PSI (pounds per square inch). Normal water pressure is generally between 40 and 60 PSI. Most homeowners prefer something right in the middle around 50 PSI.
Check with your water supplier
It could be that the mains' water pressure has increased, which is an issue with your water network. Call your water company to see if they have set the pressure higher than normal because of maintenance work. You might also find that neighbouring homes have reported the same issue.
A limit of 80 psi (551.6 kPa) is the maximum static pressure of any water supply system.
The regulator will have a screw or bolt and a locking nut system. Loosen the locking nut with a wrench and using quarter-turn increments, use a screwdriver to turn the screw counter-clockwise (to the left) to decrease water pressure, and clockwise (to the right) to increase water pressure.
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.
The average cost to replace a water pressure regulator ranges from $300 to $650 for most homes, including labor and materials. However, the cost to install a water pressure-reducing valve can vary significantly depending on your location, the regulator type, and the installation complexity.
