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 clean new galvanized metal roof with acetone?

If it is straight zincalume or galvanized iron there should be no problem however acetone is a solvent so if it is painted you may damage the paint or remove some of it. Acetone seems like a strange choice for cleaning galvanized iron though. Detergent and hard brush would be better and less toxic.


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
