Soldering a dodgy joint

[lukehoddinott]

I have damaged the end of a piece of copper pipe inside my combi boiler that joins the primary to the secondary heat exchanger. Originally the pipes connecting these were held together with a retaining clip but due to the deformation of the one end this would lead to a massive leak. Can i just solder these together or will the solder not take as there is a fair gap between them(approx 3mm)?

Any ideas would be welcome?

Probably not;

a) loads of wire and plastic - not helped by roaring (blowlamp) flame
b) You are likely to fill the pipe with molten solder
c) If you avoided the above, then the joint didn't hold, god help you

Is the pipe replaceable? If so then take it on the chin and buy a new one. If not, then a,b & c are probably not worth worrying about.

Is this your own boiloer or you a RGI?
