2 cold radiators.

[FearlessPenguin]

Hey, I recently had a leak on a heating pipe which was fixed and all sorted. However a few months later I have turned the heating on and discovered two radiators downstairs are not heating and don’t seem to be getting any hot water to them. I’ve checked the TRV pin on both and it’s working fine the valves themselves are only a couple of years old. I’ve also checked the main valve is fully open on both but no joy! Just wondering if there’s anything that may have been touched when the leak was fixed that could cause it. All other radiators are working just fine! Didn’t want to call a plumber before ruling out all obvious causes. Thanks in advance!

Have you tried bleeding air out of them?

Yep, both been bled, and checked try valves to check pin wasn’t stuck.

Very naive question but does anyone know what this part on the lockshield valve is. Shaped like a radiator key would fit? Does it have anything to do with it functioning?

Drain valve.
