To adjust the mixed outlet temperature of the valve, you need to remove the cap. The temperature should be reduced and the temperature increased until the desired set point is reached. The valve is now ready to be adjusted. To do so, turn on the heat source and place a small amount of water in the outlet.
At this point, you can turn off the heating element and allow it to cool down for a few minutes. If you do not have a thermometer handy, use a kitchen scale to measure the boiling point of your water.

How does a mixing valve operate?
The valve takes hot water from the boiler and mixes it with the cooler return water to provide a circulation of mixed water of sufficiently high temperature to meet the heating demand. The system has a constant flow rate and variable temperature control. The pressure is controlled by a thermostatic control valve.
This valve is located on the top of the unit. It is operated by the control panel located at the bottom. At the same time, it is opened and closed again to maintain the desired temperature and pressure.
How do you know when your mixing valve is not working?
It could be a problem with your hot water mixing valve if you’re certain that your water is turned off properly yet warm water is continuously dripping from your shower head. The mixing valve ball can shift if it isn’t sitting properly within the stem of the valve. If this happens, you will need to replace your valve with a new one.
What happens when a mixing valve fails?
If you notice that your hot water suddenly starts to run hotter than it should, it’s probably because your valve is malfunctioning. It might not be safe to drink hot water if the valve can’t regulate temperature correctly.
TMV valves are designed to regulate the temperature of the water in your bathtub or shower, but they can also be used for other purposes. For example, if you have a hot tub, you might want to use a water heater to heat up your water before you use it in the shower.
What temperature should a mixing valve be set at?
The valves should never be set higher than the maximum temperature of 49c (120f). Watts recommends a maximum temperature of 43C for shower and bathing water.
How long do mixing valves last?
The lifespan of tempering valves is between 5 and 8 years. That’s around half the lifespan of the hot water system, so it’s likely that your valve will need to be replaced before that time is up.
If you see water dripping from the faucet, or if you hear a popping sound when you turn on the water, you’re probably experiencing a leak. If it sounds like water is coming out of a pipe, it probably isn’t a good idea to use that water in your home.
