Hi. I want to remove a radiator and cap the rises off. It runs on a combi boiler so can I just isolate the flow and return at the boiler, remove the radiator , cap the pipes(is it ok to use the plastic click stop ends?) turn on the values and re pressure up boiler with the value below the boiler. Is it that straight forward? I have installed a bathroom but never touched central heating before. Thanks for your help.
