700kPa ((7 bar)(100psi)). Where pressures are likely to exceed 700kPa ((7 bar)(100psi)), a pressure reducing valve
must be fitted to the incoming mains supply. A setting of 400kPa ((4 bar)(60psi)) is recommended. It should be
noted that daytime pressures approaching 600kPa((6 bar)(80psi)) can rise above the stated maximum overnight.
