    Having trouble finding duel flow kitchen taps

    There seems to be a big shortage of duel flow kitchen taps, I know the trend is towards combis but there is still a lot of flats/bungalows with poor hot water pressure which means you need a duel flow tap. Any one got a good supplier of them? Thanks
