Fernox Central Heating Leak Sealer F4 500ml
Doesn't do the job
Have a leak under the concrete floor so decided to try this based on the reviews people have written. To start with it wasn't easy to pour into the radiator. Once done and left the heating on for 30 mins and turned off for 24 hours for moment of truth.... Didn't work at all. I was so disappointed. Even if it has worked still I think it's over priced for the quantity you get, at least they could have thrown the gun to pour the liquid into the rad to make the price worth. Didn't work for me hence the low scoring.

Apart from being a bit tricky to get into the system, this product is amazing!!! I was losing pressure on my combi boiler all the time, not anymore. After 2 days pressure has stabilised and held, very impressed
