This Truma pressure reducer limits incoming mains or pump water pressure before it reaches a B14 or UltraRapid hot water system. It is the current white replacement for the older black-and-blue 70020-55900 reducer. Fit it in the cold-water supply upstream of the heater's drain valve, following the flow arrow on the body. It reduces supply pressure; it is not the heater's pressure-relief valve or a non-return valve.
