A pressure reducing valve is required on the suction side of the pump when
the incoming pressure is greater than shown on the table above. In some
areas, local codes restrict maximum allowable home pressures, and in those
cases the pressure reducing valve will need to be set to lower pressures.
Note: The maximum System Pressure should not exceed 100psi.
