But, based on operational capabilities and most importantly, thinking about security, nowadays, I would advise you to choose old -style mixers. Sometimes two valves (taps), in the sense of operation, are better than one. It seems that in the presence of one handle of the distribution of water, you make less movements, and the tap itself (valve) itself is less erased, and you think that it will last longer. By no means. Check for yourself. How many times do you twist this damned handle to tune at the water temperature you need. You just don’t think about it. It seems to you that it is faster and more convenient. Well, progress goes forward, and all the more so since the neighbor already has such a tap. But if you think about it, then I assure you that you are wrong in all respects.
