The pump in question is a Mira PPT3 - (now replaced in the current Mira
range by the rather similar Enduro). It is a single motor dual
impeller - ie pumps both H & C in tandem & autostarts on water flow
detection.. It is being installed next to the DHW tank in a cupboard
on the floor above [& outside the shower room] as per the Mira
installation instruction manual.

Mira installation instructions do not indicate the preferred location
for the supply (2 pole) switch.

Should the switch be near the pump? Or should the pump be operated by
a pull cord switch in the shower room?

Is it normal to switch shower pumps on each time they are used, or are
they normally left on?

TIA

The switch is only needed for isolation and not functional switching (it
does that itself on water flow detection). So the ideal solution is to
use a switched fused connection unit where you wire it to the supply.

Normally left on.

Normally left on.


....except when my 5 year old nephew's around (the switch is outside the
bathroom at a height very convenient for a 5 year old and last time he was
here I had a very low pressure shower the next morning!)
