What is the required pressure for residential water systems?

The required pressure for residential water systems is typically designated between 40 to 80 psi (pounds per square inch). This range is considered optimal for delivering adequate water flow and pressure to fixtures without causing undue stress on plumbing components. At this pressure level, users can enjoy a steady stream from taps, showers, and appliances while maintaining efficient operation of the plumbing system.

Maintaining water pressure within this range helps prevent issues such as low water flow or inadequate performance of fixtures, and it also minimizes the risk of leaks and bursts that can occur with excessively high pressure. Beyond 80 psi can strain plumbing materials and lead to higher repair costs, while pressures below 40 psi might result in insufficient water delivery. Overall, 40 to 80 psi strikes a balance that caters well to the common needs of residential plumbing systems.
