What is the minimum flow pressure required from a faucet?

The minimum flow pressure required from a faucet is set at 8 psi according to the Massachusetts Plumbing Code. This standard ensures that the faucet delivers an adequate flow of water for effective operation and usability. A pressure of 8 psi is generally considered sufficient to guarantee that water flows smoothly and meets the expected performance standards for typical household needs, such as filling a sink or providing water for daily tasks.

A lower pressure could lead to insufficient flow, which can be frustrating for users and may not satisfy the needs for activities such as washing hands, doing dishes, or other household tasks. Higher pressures are often not necessary and could even risk damage to plumbing fixtures. Thus, the standard reflects a balance between effective performance and the longevity of plumbing systems.
