Yes, this happens quite often in older houses, copper pipe can be threaded; thus one can join them and there are several fittings that can be utilized.
On the other hand, copper tubing (K, L, M, and DWV) can be joined depending on which of the following application method is used:
Yes you can if you use the correct mechanical fittings.
Yes you can.
Yes. Use a threaded fitting, male or female as needed on the copper and screw the galvanized into it.You must use a dielectric fitting to connect copper to galvanized pipe. If you don't, a galvanic reaction will occur and the piping will corrode and leak. You can use a Dielectric Union or a Threaded Brass fitting to join the two types of piping together.UNIONS can leak the best answer would have been a dielectric nipple
Yes.
No. Galvanized pipe is what they used to use, and now should either be replaced with modern type of water pipe such as PEX or copper. COMMENT: Complete agreement. Galvanized served it's purpose and did bring water into a lot of people's homes for a lot of years. That was then, this is now. Today, it would be a dead last choice for a plumbing system.
Most codes do not allow Galvanized piping/fittings on gas piping. I have used galvanized pipe/fittings on exterior gas piping before in the state of Michigan but other states do not allows this. Check with your local code authorities.
purpleThe color of zinc
IT IS PART Galvanized don't you knowGalvanized is ZINC coating on black steel and YELLOW BRASS piping is 40% ZINC and 60% Copper and RED BRASS is 85% Copper and 15% Zinc=The problem with TOO much Zinc content is dezincification where the piping becomes brittle and to little zinc and the brass is too soft as the higher copper content.==Mixing Galvanized steel and brass or copper causes a condition of electrolytic action as your mixing ferrous metals and non ferrous metals. ( this is first year apprentice training) to prevent the electrolysis one should use a dielectric fitting=
Any piping containing Iron, usually Cast Iron, Steel & Galvanized pipe.
There are copper fittings that will connect to galvanized.
A threaded copper fitting on the copper side, male or female, and the galvanized is screwed into it.
Depends on the water quality and what type of galvanized piping was used
They don't rot out like galvanized does, easier to work with, good with pressure.ANS 2 - ALL copper pipes eventually develop pinholes. MUCH better to go PEX for interior water piping !
Because1- water conditions would not allow copper tubing do to the hardness and PH factor2- Labor was cheap and threading galvanized was cheaper then installing copper3- Galvanized is still used in many locations as people do not like to drink water coming out of toxic plastic piping
