What is point of use mixing valve?
Point-of-use TMVs accomplish this by pre-mixing hot and cold water to safe and comfortable temperatures at bathroom sinks and other fixtures. This preset temperature eliminates the need for users to touch faucets, or it feeds a sensor faucet directly.
What happens when a thermostatic mixing valve fails?
Your water temperature isn’t right If a TMV valve stops working correctly, then you may notice that your hot water suddenly starts to run hotter than it should. If the valve can’t regulate temperature correctly, it might not be able to cool hot water down enough to make it safe.
How much more water do you get with a mixing valve?
By installing a mixing valve and slightly increasing the target temperature on the hot water heater, you can increase the capacity of a tank – in some cases by up to 50%.

Inconsistent Hot Water 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.
Why is my hot and cold water mixing?
Crossover occurs in a DHW distribution system and is the result of a combination of a faulty fixture valve, or an uncontrolled open circuit at the point where cold water and hot water pipes join to mix, and a pressure imbalance between the hot and cold water subsystems.
How to select hot water sizing method for Honeywell mixing valve?
