Hi All,
All my rads are connected via microbore copper pipe to a 22mm manifold. The lockshield valves on the downstairs rads all have a drain facility as you'd expect, but I have two questions:
1. When draining the whole system, am I right in thinking that I should drain via whichever lockshield valve drain point is most convenient, then drain whichever individual rads I need to work on?
2. My LSV's all look like this:
How do I open the valve AND connect a hose when the drain point looks like that? I don't mind a few drops of water but I really don't want to risk spewing central heating gunk all over the hallway if I'm not fast enough to fit a hose and tighten the hose clip! Any suggestions?
Thanks
Steve
