Hi all
I need to drain downmy combi central heating system to put a new rad and valves in each end. The drain cock downstairs isn't opening properly and it started to leak once fully turned off. It might be a type B drain cock (picture attached) which has been put on my 15mm compression.
Any ideas how to drain down without flooding the place as need to remove the drain plug!
Thanks very much
