Radiator leak sealant and bleeding

smcqis

Our pressurised system was slowly losing pressure over a number of weeks so a radiator leak sealant was added to the system to seal up any minor leak. 

My question is how long after this has been added can I bleed the radiator as I don’t want to bleed it and the sealant take effect and part seal it?

When you bleed the rads you should only be letting out a fraction of the water. The sealant itself shoudlnt affect your bleed valves as their "mechanical".

As said, the sealant won't affect the bleed valve - it's too big an opening, and also because it's going to move - so you can 'bleed' right away.
Has the sealant done the trick? Any idea where the leak is?

Thanks, I think it has worked been a week and haven’t noticed a change in pressure, will reassess in a months time. Fingers crossed

We had ours done 7th January and it seems to have worked.

Huge relief as specialist leak detector company didn't manage to trace it but no idea what we'll do if (when?) it happens again. 

Fingers crossed for you
