Is it okay to connect copper pipe to brass to galvanized to brass and back to copper or will it cause a reaction that will corrode the pipes?

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.

Can you connect copper to galvanized using only a bronze fitting?
There are copper fittings that will connect to galvanized.
What do you need to connect copper to galvanized pipe?
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
What makes copper corrode?
usually copper corrodes from a chemical process known as "galvanic reaction". This is caused when copper is touching dissimilar metal such as steel or galvanized. a di-electric union is used to prevent this. further questions Jeff at jlgprop@yahoo.com
Can a 2.5 galvanized dielectric union be used to connect black pipe to copper pipe?
Yes
What chemical reactions will happen if you connect galvinized copper and brass metal pipes?
There is no chemical reaction that will happen if galvanized pipes are connected to copper pipes via a brass intermediary. The reason is that brass does not react to either copper or zinc, the mineral used to galvanize metal pipes.
Can bronze fittings be connected to galvanized pipe?
yes. Copper to Galvanized must have a dielectric fitting to avoid a galvanic reaction causing corrosion and eventual leaks.
Why do copper pipes carry hot water corrode faster than pipes that carry cold water?
Heat speeds up chemical reactions. As corrosion is a chemical reaction, copper pipes at a higher temperature will corrode faster
Why should you not replace a section of galvanized iron pipe with copper pipe when doing plumbing repairs?
Because you will then get a 'galvanic reaction'.
What fitting is required to join copper with galvanized pipe?
A threaded copper fitting on the copper side, male or female, and the galvanized is screwed into it.
Can you connect copper to galvanized by using a bronze fitting?
Yes! The best copper-to-galvanized connection is made using a brass nipple in between the two dissimilar metals. The nipple should be a minimum of 2 1/2" long (preferably six inches long). Bronze is an alloy (copper + tin). Brass is an alloy (copper + zinc).
If steel and copper were in contact in an electrolyte which would corrode?
Steel will corrode as the iron in it is more reactive than copper.
What makes copper not rust?
"Rust" is the result of a reaction between iron and oxygen. Copper has no iron in it, so does not rust. It can corrode, though, and yield a bright whitish-blue material.
