System Pressure

It is important to always maintain continuous positive pressure to customers. The minimum recommended pressure is 35 psi with an absolute minimum of 20 psi. Maximum pressure should be no more than 100 psi. This maximum may be exceeded because of poor design and placement of zone separation boundaries. Additional pressure-reducing valves may be installed in the distribution system to reduce the pressure to within acceptable limits. Water hammer may be reduced by minimizing pressure fluctuations in the system.
