Thermostatic Mixer Valve

Cleaning the thermostatic mixer valve

As water hardness varies per region, the filters inside the valve may become clogged which will result in reduced flow and reduced performance of the valve. To clean the valve:

Shut off the water supply with isolating valves on both hot and cold inlets.
Unscrew the Knob Levers and the Grub Screws. Then remove the Control Knobs and Kelda Faceplate.
Remove the Screw, the Knob Adaptor and Temperature Control Ring from Thermostatic Cartridge.
Now remove the cartridge with a wrench or similar tool.
Rinse the Filters to remove dirt thoroughly, soak them in a suitable de scaling agent.
The housing of the Thermostatic Cartridge must also be cleaned thoroughly with a clean cloth. The O-rings of the cartridge should be greased.
Reassemble the Thermostatic Cartridge ensuring Temperature Control Ring and Knob Adaptor point to 12 o’clock position as per step 4 & 5 of the ‘Resetting Valve Temperature’ section.
Ensure that the system is secured tightly. The water supply can now be turned on from the isolating valves.
Check water temperature is okay, and if not then calibrate as explained in page 30 and check again.
