Help sealing a copper cylinder

    Leak in the copper cylinder
    I have a leak in my hot water copper cylinder, I thought it was the fitting from my heating to the coil inside. I removed the fitting and found that the leak is coming from the 1" male tread on the end of the coil, and the wall of the cyclindermad.gif!

    I have the cyclinder drained down and was thinking of soldering the joint, or any other suggestions that anybody may be kind enough to share?

    Kind regards,

    Didn't have any flux so the solder didn't stick!! Off to get some now, or would the likes of Tec 7 be a better seal on the joint?

    Solder probably isn't the answer, its for joining not filling. Even if you get it to hold, it won't last.
    JB Weld or something similar will do the job, I have never used Tec 7 so can't comment.

    You can use soldier to fill small holes, however I don't think this is the answer here.

    You may have to bite the bullet and just replace the cylinder.
