Rated 5 out of 5 by from Sealed ? Hopefully this seals a leak on a sealed system that takes a few weeks to drop the pressure, Time will tell. very easy to use and inject into the system and will use this type of product in future. One odd thing is the boiler pressure now rises to the red so not sure why that would be. (1bar up to 2.9 bar?)

Rated 5 out of 5 by from Only a week Early days but I had a leak going down by about 0.5 bar per day. I could not find it and didn't want to start lifting floorboards. This was easy to introduce to the system by shutting it off at either side then removing the drain valve Bolt. I needed two doses to work but so far it's holding after a week of winter use. This has potentially saved me untold drama of finding the leak. Lucky I stumbled across it.

Asked by: aarun
Hello and thank you for your query. YES you can use Sentinel Leak Sealer in an open system. It can be added to the system in a number of ways. For open vented systems with an overhead F&E tank, dose via the expansion tank during the final fill. Kind Regards, Sentinel Customer Service

Will this stop the compression fitting of a TRV weeping?

After replacing a rad and tightening the 1/2 in rad connection the 8mm compression fitting on th TRV outlet has started to weep, Will this product stop this type of leak?
Asked by: DaveMacca
Hello - Thank you for your query. As the leak is external you would be better served using the Seal X product rather than circulating Leak Sealer in the whole system just to address this leak. Kind Regards, Sentinel Customer Service
