Ok so after a few dip tube designs that worked ok.. i thought why not just used 1/2 copper with fittings

I noticed that i can get the fittings to stay together relatively well by putting a wrap of teflon tape around the slip fittings. Certainly well enough to do a brew but then when you take it apart to clean everything you have to redo it everytime.

Aside from lead solder is there any good way to join the pipe to make this option work? Any thoughts??

Plumbing solder is lead free and safe in the boil.

ditto, you can get silver solder, and its super easy to sweat it on to copper. Cheers,

We do the same.... But, for our dip tube that goes three our false bottom, we use a compression fitting into the coupling on the wall of the kettle. Its cheap and Works great.

Yeah solder is the way to go, just be sure to mark everything so it lines up after you solder it.

Ah ok that makes perfect sense, completed the solders and its a good seal, the fit is perfect.

Do i have to do anything to clean the pipe before i brew with it?

PBW, oxyclean, barkeepers friend will all clean up the copper.

Just don't do any extended soaks and you should be fine.

Main thing is to rinse well after cleaning to flush away the flux

You can also do a good "initial" cleaning of copper with vinegar.
Give it a good soak, and it works wonders!
The hotter, the better...........You can clean your coffee maker with it beforehand, and soak your copper stuff with the hot batch of vinegar you just "brewed".

Thanks for this idea. I bought a stainless diptube online for too much. I never thought about this. I just did a huge plumbing job at my house and have all the parts I need already. Cheers for the diy idea!
