I have an unusual situation whereby thewater supply is often variable pressure or even none at all. So the whole house is plumbed for either mains supply (no pump) or storage tank supply (pumped)
But to save on pump running costs I only want to have the pump running when the shower is being used. I dont need higher pressures for basins and toilets.
I am looking for either battery or low voltage remote switching, so that the pump only runs when the shower pipes are running. Can any one help me please?
