I will be installing a Shower mixer shortly and need to confirm a few details. I have 2 qualpex pipes fed into the bath area on the wall. The pipes are in the attic but not connected to anything. From what I know I need to fix once pipe to the cold water feed(is this to the tank in the attic) and another to a hot water feed. There is no power supply in the bathroom so it will pressure/gravity fed system which I will install. Are there do's and don't to this as I'm sure its not as easy as this. Do I connect the hot feed to the emmersion tank??
