How do I adjust the temperature on my mixing valve?
To adjust the mixed outlet temperature of the valve, remove the cap to gain access to the adjusting spindle. The spindle should be rotated-clockwise to reduce the temperature, counter-clockwise to increase the temperature until the desired set point is reached.
Which way do you turn a mixing valve for hotter water?
automatic mixing valve clockwise makes the outgoing water temperature cooler. Turning the Watts mixing valve counterclockwise makes the outgoing water temperature hotter.
How does mixing valve work on underfloor heating?
The tempering or blending valve is the heart of an underfloor heating system. It blends colder water from the underfloor heating system return with hot water from the heat source to supply the correct temperature of water to the underfloor pipework.
What temperature should a mixing valve be set at?
The safe and unsafe temperatures in water heaters The recommended and also factory set temperature setting is 120 F. If the temperature is around 120 F, it will take 5 min for 2nd and 3rd-degree burns on the adult skin. For the temperature of 130 F, it will take 30 sec.
Why is my mixer shower too hot?
Thermostatic mixer showers: If the temperature of your thermostatic mixer shower keeps fluctuating wildly (getting boiling hot or freezing cold), the thermostatic cartridge probably needs replacing. If the shower works fine without the head attached, then the head is reducing the flow and needs cleaning.
Can mixing valves go bad?
Older model hot water mixing valves age over time and can break down with usage. As a result they can begin to fail in correctly controlling water temperature.
How do you test a mixing valve?
Thermostatic Mixed Valve Testing Procedure
- Measure the mixed water temperature.
- Isolate the cold water supply to the TMV.
- Wait for at least five seconds.
- Check if the water temperature is below 46ᵒC.
- If there’s no significant temperature change (2ᵒC or less) it means the valve is performing optimally.
