What is the typical pressure range for water distribution systems?

The typical pressure range for water distribution systems falls between 40 to 80 psi, which is generally considered optimal for ensuring adequate water flow and delivering water effectively to consumers. This pressure range is necessary to overcome friction losses in the piping, provide sufficient pressure at fixtures, and allow for the proper operation of appliances that rely on water, such as washing machines or dishwashers.

Maintaining pressure within this range also helps prevent issues such as low flow rates, which can lead to inadequate service delivery, or excessively high pressure that could result in pipe bursts, leaks, or increased wear on the system components.

Other pressure ranges mentioned, such as 20 to 40 psi or 30 to 50 psi, are typically too low for standard residential or commercial requirements, and can cause problems with water delivery. The range of 60 to 100 psi is usually on the higher end, which while occasionally necessary for specific conditions, can lead to pressure-related damages in many standard systems. Thus, the 40 to 80 psi range is recognized as a safe and functional standard for water distribution systems.
