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.

Can you connect galvanized pipe and copper?

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

Can I connect brass to galvanized steel pipe?

Not with out an dielectric fitting to prevent electrolytic action from taking place or dezincification of the brass if it is yellow brass ( 60% copper 40% zinc ) Red Brass 85 % copper /15% Zinc will corrode the galvanized piping

Addition of copper sulfate will poison your algae. It will also corrode any brass or zinc (galvanized) that it comes in contact with.

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

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.

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.
