BUT>>>>Here is the problem...the tank was massively rusty inside (outside perfect) so I used TAPOX tank sealer. I am a great fan of this product and used it lots of times on different tanks with total long lasting success. Unfortunately what must have happened is that on tightening the tap I must have slightly rotated the stub within the tank as maybe the metal was extra thin due to corrosion. So now I have to get the leak fixed but what with the TAPOX inside, trying to use a hot flame isn't going to do this sealant any good. I was thinking that maybe TIG BRAISING might be possible? (thoughts on this?)
I also considered that to get a firmer stronger fixing it might be better to make up a new male threaded fitting in the shape of an inverted top hat so that the wide flange of the fitting (about 22-25mm in diam?) could be TIG welded to the bottom surface of the tank after the original stub had been removed. At least there is good metal surrounding the hole. This would avoid the original threaded tube (stub) simply twisting again when tightening the tap.
Any thoughts or personal stories on these tanks?...Much obliged for your ear as ever...All the best.
