A stupid question maybe ? I have bought a load of vertical radiators to replace the older fashioned ones in my house I am renovating.Very nice and very modern ! I have been told by my plumber that the wall behind them needs to be decorated before they can be fitted as it can be seen through them ! If they are replacements surely I need the originals removed to decorate behind these as well as they are going in same position mostly ? What about future decorating ? A problem I had not anticipated ! Surely there is a way of shutting the pipes connected to them off ? Look forward to your answers and advice.
