Hi all, 2 quick questions about bleeding CH systems. I have an open vented system and have been having to bleed it a fair bit recently.
On my cylinder and 1 radiator the screw that you loosen to bleed has become a bit mangled and I'm struggling to both loosen and re tighten them. I'd like to buy some spares in case I end up not being able to get 1 tightened back up , what exactly are these called? I take it I can buy them from screwfix or B&Q?
Also, should the system pump be bled? I see there's a screw on the front which looks like it is for this purpose
Thanks in advance
