Leaking lockshield

[Adam75]

Hi

I've just reinstalled one of our radiators and as soon as I opened the lockshield the lockshield started to leak from the spindle/screw. I've tried to adjust the screw slightly in the hope is would stop but no luck.

It's a fancy Quinn straight lockshield with an inverted screw as the spindle! the leak is coming round the screw.

I want to avoid taking the rad off again and replacing the lockshield as it's a tall column rad so it's quite a pain to drain it etc.

I'm wondering if I could get away with draining the heating system (combi boiler) and undo the lockshield mechanism to replace the o-ring.

Or is there a simpler way?

I'm hoping it seals itself as it's only a small drip and we live in a hard water area but I think that is wishful thinking.

Thanks

Adam

Where is the cap that covers it?

It as a seal in it, just replace the cap, when you have the lockshield in the required position.

I did put the cover back on but it still leaks.

The leak has slowed overnight so maybe the limes scale is enough to seal it

Replace the seal in the cap

The cap does not have a seal in it. I've got 2 of these lockshield valves and neither has a seal.

I've added an o-ring to see if that helps
