Ares three-way tap

What is the difference between single and dual flow taps?

Single flow taps are becoming more common in the UK. The water mixes in the body of the tap and spout and gives a greater flow due to larger outlet/spout diameter. They provide for an even temperature mix at spout exit. Non return valves must be fitted if on an unbalanced system.

Dual flow taps used to be standard in UK homes. These are where the Hot water is fed through the centre of the spout, separate from the cold. The spout will not get too hot to touch. Non return valves are not required in these instances when installing a dual flow tap.
