What is the typical service pressure range for residential water supply?

The typical service pressure range for residential water supply is between 40 to 80 psi. This range is considered ideal for ensuring that a household has adequate water pressure for various activities such as showering, washing dishes, and using appliances. Pressure that is too low may result in insufficient water flow, while pressure that is too high can lead to potential damage to the plumbing system and fixtures.

The range of 40 to 80 psi strikes a balance, providing enough pressure to meet user demands while minimizing risks associated with high pressure. Most plumbing systems are designed to operate efficiently within this range, making it the standard for residential applications.
