Dual or Mixed Taps? The Pros and Cons

Few peculiarities in the British Isles astound any visitor as much as the absence of mixed taps in a bathroom or kitchen. And few criticisms of local traditions by visitors perplex the British as much as why they should have mixed taps.

These may be two extreme sides of the debate but the number of British homes where mixed taps are the norm is definitely the minority. Unless you modernise the plumbing when you buy a new home, there will always be a dual tap set over a sink or bath, somewhere. Even in a new build house. So what is everyone complaining about?

The Traditional View

British homes traditionally connected the cold tap to the mains water supply and the hot tap to the hot water tank. The separation was there to stop any cross contamination from the hot water system, in accordance with Britain’s complicated building regulations. It was also about money. It was easier to divide up the hot water from one heating session of the hot water tank – whether generated by an open coal fire, direct electricity supply in an immersion heater or through the central heating system – between multiple members of the family by rationing the use of the hot tap.

But modern dual-flow taps are fed by separate hot and cold water pipes. The mixing only happens inside the tap and the relative flow of hot and cold water may be regulated by the user. At least there is no chance of being scalded, as has been the case with a single-flow hot water tap with those who did not appreciate how quickly the very hot water passed along pipes in any house.

Yes, say the traditionalists, but the single-flow bath taps have a better flow rate. You can manage each hot and cold tap better. The water will mix in the sink. If you keep a dual-flow tap running without using a plug in the sink, as often is the case, you will waste water.

Modern Comfort

No, say the modernists. Probably the most important development in plumbing technology has been the single-lever mixer tap. The lever can be styled to any length or width, with precise and extra wide angles to ensure ease and comfort of use. You can work it even of you are injured or disabled, using an elbow, a foot, a knee or a forehead. You will have just the right amount of water you need, at the temperature you prefer, whenever you like. And as an increasing number of homes have water meters, water will not be wasted.

Of course, there is a traditional look to the old two-tap system. A couple of Victorian polished brass taps can look superb when attached to a large cast-iron bath. But think of the precise control and smooth handling of water flow and temperature you can achieve with a mixed-tap system. Modern finishes on the plumbing also mean that you don’t need to spend time cleaning and polishing the metalwork.
