You might even consider putting a small bit of PVC between them because those 2 metals will each cause the other to corrode.
yes. Copper to Galvanized must have a dielectric fitting to avoid a galvanic reaction causing corrosion and eventual leaks.
If you do connect copper pipe to galvanized pipe, you will need a dielectric coupling or else the galvanized pipe will corrode. Same with connecting galvanized pipe to brass fittings. Brass is an alloy that contains copper and therefore the same electrolytic properties will exist unless a dielectric coupling is used. Hope that helps you out.
GI Pipe is "Galvanized Iron" Pipe. These days the pipe will likely be made from steel rather than iron.
You should use black pipe -- Galv. pipe will flake off inside of pipe
Sharkbite fittings are generally effective for connecting to galvanized pipes, as they are designed to work with a variety of pipe materials. However, it is important to ensure that the galvanized pipe is in good condition and properly prepared before using a Sharkbite fitting to avoid any potential issues with leaks or damage.
Yes.
ya the galvanized pipecan be use in undergrounds,,, because it is an iron pipe
Because you will then get a 'galvanic reaction'.
Yes
Galvanized Iron pipe
yes
Galvanized pipe will be silver/gray color. Copper will be copper. Use a magnet, it'll stick to galvanized pipe but not to copper. Drinking water lines should not be black steel pipe.
