1. Both supplies are tanks
2. Pipes will be less than 3m from the pump, Im not sure what you mean by gauge. From the hot and cold tanks pipes go to the rest of the house and 2 pipes goes to the shower from hot and cold tanks respectively.
3. I know my shower is negative head, distance is...
I'm looking into fitting a pump for the shower. I want to know if it is possible since the pump will go just before the mixer valves.
The pipes from the storage tanks are link to the shower and the rest of the house, hence I want to connect the pump to the pipes that go to the shower.
Thanks
