We have a large bath and so to allow it to fill without the water ending up cold the hot water temperature needs to be quite high. This means that the hot tap at the sink is too hot to put your hand under. I want to fit a blending valve just for this tap so the temperature is reasonable. The sink is going to be replaced some time (late?) next year and it will have a monoblock tap. So, I am looking for a cheap
15mm blending valve - accuracy of temperature not important, nor is long-term life. Any ideas?
