FROM A TANK!!!!!!!
Why would he go to the trouble of installing a tank into the loft, running a cold feed to it. running another cold feed from the tank to the shower all to give you less pressure than the mains pipe he has there already!!!!!!!!!!!!!!!! If he was going to do this why not just put in a bar mixer of the combi???
Jesus I hope you dont fit many of these set ups!!!
