I'm buildding my mash tun and was putting the copper manifold together when I noticed the ring of solder on the copper connections. Is this something I should worry about, are there solder free connections out there?
Yes there are solder free connections but if you have solder one's already then hold them in a vice grips and in a frame and the solder will fall out.
You can order the solderless tees & bends from the plumbing counter @ TJ Mahony in Ballymount
Thanks Dempsey, I'll give that a go first then if it doesn't work get solderless ones.
I dont know how worried i would be about solder.
They no longer use lead or tin.
I think its a form of zinc thats used nowadays.
Is it brazed or soldered ? solder melts under 450c while brazing happens above 450c . These are clearly temps nobody will be using on here , but it will give you an idea of the metals used . If its a good clean braze you`re prob grand ? Or at least less chance of something leeching out into your brew .

Can you just burn these things until they just flow out?
Put some in the flame on my gas hob and it fell off within minutes.
It was when I soaked them in citric acid while cleaning up I noticed a white substance coming out. I haven't tried the vice grips yet, but it would be easy to put them over a gas ring and melt it off just in case.
Just finished removing the solder or whatever it was. 2 mins over the gas ring and it all melted of. Thanks all for help
I assembled one recently and used the cooker to solder it all together. Working a treat so far.

People usually like to be able to pull the copper pipes apart for easy cleaning :)
