Draining off sealed system central heating...Any tips on doing this?
Its a potterton boiler with a maxflow cl 170 tank with an expansion vessel (red blob) that sits on top.
Ive been having problems with this and have admitted defeat now and need help, basically i need to drain down system so im able to cut into the pipes and install a new rad.
I did this all at my house with a combi with no troubles but this just seems alot different.
