Paloma leak

Put some solder over the top of the split - tried to close the gap by pushing in the split first - not sure the solder is much use now there is no lead in it - health and safety - all the pensioners still around will have been drinking via lead pipes for 50 yrs!
The first two attempts ended in failure and a wet face - I think I was trying to do a neat job and the solder was too thin - the 3rd attempt appears to be holding, although I have not tried it with hot water yet.
Would have been more successful to take the heater off the wall and turn it on its side - the solder would then sit on top of the split without dripping down the side of the unit.
Might look out for a second hand one off eBay although some on there might have faults!
