Rated 5 out of 5 by from Handy stuff My neighbor recently told me about this and it works really well. Used it to seal round new valves and olives being put on a new radiator in my spare room and it done a first class job, no leaks whatsoever. First class.

Rated 5 out of 5 by from Fernox Jointing Compound Very handy stuff, had a pinhole leak somewhere around the joint were the pipe from my Willis type immersion goes into the hot water tank. Slathered a load of the Fernox around it and hey presto no more leak - that's saved me the £500 the plumber was quoting as he said the tank had to be replaced!
