Has anyone used and had success with one of the central heating leak sealers? My sealed system has started to lose approx 0.5bar over a 4/5 day period. I can find no leaks. My concern is that the leak is on the downstairs level where all the pipework for the system is buried in the concrete floor. This concern is well founded as this would be the 2nd leak we have experienced in the < 1 year we have lived in the house. The first leak resulted in system pressure reducing to zero in about 2 hrs though and we had to remove the solid wood floor and dig up the concrete. This leak is much much smaller and would be almost impossible to locate if in the pipes in the concrete floor!
I was thinking of using the Fernox central heating leak sealer product.
Thanks
