I was told a long time ago that brass nipples (or couplings) would act as a "dieelectric break" when used to connect an indirect waterheater. Is there any truth that the brass is indeed some kind of break? I've recently seen some corrosion the causes my to wonder if there is any merit to using them. Any opinions, or even better, any documented proof?
thanks,
Marco

Open vs closed
Closed systems, ie: boilers or boiler connection to indirect DHW coil do not need dialectric fittings. Open systems, ie: potable water side do, if the connections are made between dissimilar metals. A brass nipple 4" long or longer, counts as a dialectric fitting. That is if you are covered by the UMC or UPC.
