Another quandary, i couldn't find a copper needle valve, so used a brass one, is this safe?
Will i get Lead poisoning?

Also, i could not find a compression fitting to fit my thermometer so I soldered a copper tube with about the inside diameter of the thermometer stem to the top cap, and used plumbers tape to complete the seal.
Will the Plumbers Tape contaminate the finished product?

Thanks anyone who could shed some light on this
