I was wondering.. if the manufacturer's spec for a shower pump states that the shower head much be at least x amount below the bottom of the cold supply tank would it work to just turn on the shower with the shower head on the shower tray floor (provided it's low enough) to trigger the pump, then put it back up above head-height?
Also, what is it triggers the pump? Pressure or flow? Reason I ask, I'm wondering whether a pump on the hot supply to a venturi shower mixer would be more likely to trigger due to the 'negative pressure' generated by the venturi system?
