Rated 4 out of 5Â by loft Sealed some invisible leaks
Added this to a customer's sealed heating system which kept losing pressure but no visible leaks, now it's fine.

Used to solve a leaking compression T which was in a difficult to get at location and would have required a drain down and new inhibiter. The leak was generating approx. 1 pint every 3-4 hours to give you an idea.
The liquid is very thick, I drained a few of pints from a rad in a tiled area and removed the whole bleed valve and used a 6inch cut of garden hose with a funnel to get it directly into the system. Took a good 5 mins to get it all in. Let the heating run on a boost and by 30mins the leak had virtually dried up and after 1 hour was good to go. Saved hours of work and wasn't looking forward to recharging the whole system, and bleeding it out. They didn't have the Fernox product in stock at my branch but am very pleased with the performance of this
