This pressure could lift water a distance of about 8 m (1 psi = 2.31 ft of water). In practice, this lift is much smaller due to lack of perfect vacuum in the impeller and friction losses in the intake pipe. The practical value of maximum lift differs between pumps, but it is usually no greater than 24 ft.
