My plumbing system consists of gravity fed low pressure hot water and mains fed high pressure cold water can I use a thermostatic mixing valve on this type of system?
A – Yes, provided that the differential pressure (the difference between the hot and cold water pressure) does not exceed a 10:1 ratio a thermostatic mixing valve can be used without any other controls. If the pressures exceed the 10:1 differential then a pressure reducing or pressure equalising valve should be used to bring the pressures within the valves working parameters.
