Why Britain Uses Separate Hot And Cold Taps

Why you don't cross the stream in Britain.

In many, if not most, British homes the ONLY "pressure faucet" is the kitchen sink. Every thing else is gravity fed from the storage cistern in the attic, which has a float valve to keep it full, when pressure in the mains is adequate to lift the water to the attic. In these home you CAN use a "mixer" faucet, except for the kitchen, because both are fed from the same source. If the faucet is connected to a cold pressure source, it would "overwhelm" the hot water side, and possibly back up into the storage tank and overflow it.
