PRESSURE DROP: Not part of the sales advertising campaign where combi boliers are concerned. Does anyone own a combination boiler that does not drop pressure. Hands up all those owners of a combi boiler who know how to repressurize it. Hands up all of the combi owners who even knew that you would need to. How many HAPPY combi boiler users are out there. !! Warning these boilers are a danger to health and sanity. !!
