silver and copper in one rig will it work?

the thing that i plan on doing is to have a silver res with a copper block in a mini fridge
the only thing is will the silver eat the copper or the other way around
please need info

i've never seen the question about silver and copper together however, i beleive with a good water wetter you won't have to worry about it...my setup is all copper with brass fitting so i added water wetter to prevent the breakdown of either material =).
