The function of a thermostatic mixing valve is to deliver water consistently at a safe 

temperature. In keeping with every other mechanism, it cannot be considered as 

functionally infallible and as such, cannot totally replace a supervisor’s vigilance where 

that is necessary. Provided it is installed, commissioned, operated and maintained 

within manufacturers recommendations, the risk of failure, if not eliminated, is reduced 

to the minimum achievable.
Mira thermostatic mixers are precision engineered and should give continued safe 

and controlled performance, provided:
