Solder on copper connections for mash tun

[Fal]

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?

[DEMPSEY]

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.
