Currently running one power shower in the main upstairs bathroom, the MI's that came with the pump says it can run a second shower. The MI's don't say how far away the shower can be. The second shower will be about 8m from the 1.5bar watermill pump, will the pump be able to cope with this distance or should I upgrade or add a second pump. I know pumps are generally designed to push water so If adding a second pump is the way to go are there pumps that could be fitted closer to the shower as there is no room where the 1st pump is.
