If the copper is big enough, you can treat it as if it were cast and use packing and sealant. If the diameters are too different, you can use a rubber coupling to connect the two.
When I have to connect copper to lead "D" I usually solder the copper to the lead or wipe a lead joint depending on the diameter To connect copper to cast iron ,.... If there is a hub I caulk the copper directly into the CI with oakum and poured lead (molten) OR one can solder / braze a female adapter fitting and screw the copper into a CI female fitting

You don't, you remove the plastic junk and replace the toxic plasatic with cast iron
For supply, it is copper and galvanized iron. For waste, ABS (plastic) or cast iron.
Will that work to eat up the Zinc(anode) instead the iron pipe ?Will the copper lead the ions to the zinc, or its resistivity will jeopardize the sacrificial protection combination ?thank you
The iron is higher in they reactivity scale than copper , Therefore the copper will be replaced by iron to make iron sulfate and copper by itself.
SO they don't melt on the stove. Also they are durable, good conductors of heat. Copper pans are much more expensive, and so are cast iron ones.
No, copper is less reactive than iron.
Since iron is a more active metal than copper, the iron would replace the copper in the copper sulfate, forming iron sulfate, and releasing elemental copper. The copper will not shape itself into a copper vessel, so eventually, the iron sulfate would leak out of the iron vessel, and eventually, if there is enough copper sulfate, the iron vessel will cease to exist.
Contacting the iron powder with an aqueous solution of copper (II) salts will produce a copper coating on iron powder: Iron is higher in the electromotive series than copper and therefore will displace copper from the solution, resulting in copper-coated iron and dissolved iron cations. When all of the surface of the iron powder has been coated with copper, the iron will stop reacting because it no longer has access to the copper ions in solution, the access of the iron being blocked by the layer of copper coating the remaining iron powder.
iron + copper sulphate ''goes to'' iron sulphate + copper
Iron is more reactive than copper.
