If there is a residual flow during the commissioning or
the annual verification (cold water supply isolation test),
then this is acceptable providing the temperature of the
water seeping from the valve is no more than 2°C above
the designated maximum mixed water outlet temperature
setting of the valve.
Temperature readings should be taken at the normal flow
rate after allowing for the system to stabilise.
The sensing part of the thermometer probe must be fully
submerged in the water that is to be tested.
Any TMV that has been adjusted or serviced must be
re-commissioned and re-tested in accordance with the
manufacturers' instructions.

Purpose
Since the installed supply conditions are likely to be
different from those applied in the laboratory tests it is
appropriate, at commissioning, to carry out some simple
checks and tests on each mixing valve to provide a
performance reference point for future in-service tests.

1. Check that:
a) the designation of the thermostatic mixing valve matches
the intended application
b) the supply pressures are within the range of operating
pressures for the designation of the valve
c) the supply temperatures are within the range permitted
for the valve and by guidance information on the pre-
vention of legionella etc.
2. Adjust the temperature of the mixed water in accordance with
the manufacturer’s instructions (page 63) and the requirement
of the application and then carry out the following sequence:
a) record the temperature of the hot and cold water
supplies
b) record the temperature of the mixed water at the largest
draw-off flow rate
c) record the temperature of the mixed water at a smaller
draw-off flow rate, which shall be measured
d) isolate the cold water supply to the mixing valve and
monitor the mixed water temperature
e) record the maximum temperature achieved as a result
of (d) and the final stabilised temperature
NOTE: The final stabilised mixed water temperature should
not exceed the values in Table A.
f) record the equipment, thermometer etc. used for the
measurements
