I want to replace a radiator but would like to know step by step of how to drain the system..
*For some reason I have two tanks up in the loft one big one small no drain cock but I've been told to tie the floats arms to a batten...?
*I have an old boiler with all the lagging round in the airing cupboard, there is a drain valve which i can connect a hose to but, there's also a drain valve on the radiator downstairs which i want to replace...! Which drain valve do I use to drain the system?
many thx
