My plumber plans to put in a separate dual-impeller pump for each of
my three showers. A colleague has suggested that since this is a new
installation it would be better to have 2 better single impellers (one
hot, other cold. Does anyone have an opinion on this?

Many thanks

Hi Potsie,

Yes ! The answer would be to fit Central Heating Pumps to both your hot
and cold supply pipes to lift the pressure in the whole system and not just
to the showers. That way you cut down on maintenance costs, only to pumps
to look after, shower installation costs, you could install a larger range
of decent showers, and running costs because the power used by two central
heating pumps on demand switches would be less.
