Internal leak sealing liquid

[WaterTight]

For adding to central heating system and sealing leaks in inaccessible places.

Anyone ever tried this? Seen it advertised. Don't need to use any or anyting, just wondered if it works.

And actually, how it works...

i have in the past used the fernox F3 leak sealer, it looks a little bit like pva glue and have a thick consistency, the way i think it works is that because its thick it basically blocks up the leaks, as it is circulated round the system, im not over keen on the stuff as it can block plate heat exchangers in combis or so ive been told, but the times i have used it on ch systems its never failed to stop the leaks. but is only works on small leaks i.e 1 drip per second or less.

no way would i use anything like this

sounds like throwing an egg in a leaky car radiator. works but would you really want it doin to your property??????

there,s nothing wrong with it at all and i would recommend everyone uses it in an old system that is being sealed , it does not interfere with the running and does exactly what it says , seals small leaks that cannot be seen or traced in a system , a godsend in the world of social housing and the like.

Must admit to using it twice .
Once on a hideaway heat exchanger leaking December 23rd 2005 worked a treat . We are fitting a new boiler there next week it has held all this time.
And last year on a leak somewhere on heating pipework all buried in the concrete floor

i even used it on my sons moped when he holed the radiator with a stone , instant seal and lasted the life of the bike,

It works, but has to be a last resort.

It works, but has to be a last resort.

As danny says
I have used it and it does work but has to be of a last resort
