I have recently bought a house with a new sealed combination boiler installed. All is well with the thing until we decided to have a thermostatic mixer shower installed in the bathroom upstairs. It has transpired that the cold water pressure isnt sufficient to open the non-return valve on the cold water side of the mixer, which means that the pressure is low and sometimes only dribbles out until the mixer is thumped. Taking out the non-return valve is an option but it does mean that there is a risk of the hot water feeding back into the cold water tank. The reason the cold water pressure is low is that it is still fed to the bathroom via a cold water tank in the attic. Logic dictates that with a sealed combi boiler the need for a water tank is done away with, however one still exsists! My question is, can I get rid of the water tank in the attic and feed the bathroom with the rising mains that feeds the tank?
