I need to fit a pump to my very low pressure system with a head of just 1m from cold water tank to new fitted bathroom. I propose fitting it to supply the whole house, one bathroom, one seperate shower room, a downstairs cloakroom and kitchen.
Could any experienced user answer some simple questions regarding pumps like:
Is it better to fit seperate single flow pumps to hot and cold supply from header tank which feeds the whole house?
I have a shower head which is fixed at about the same height as the bottom of the cold water cylinder, should I therefore use a negative head pump? And if so, will this be OK for the rest of the house?
If I install a double flow pump(hot and cold) , what happens to the impeller of the second flow when only one feed requires water, say when flushing the toilet?
