: I read, somewhere on your website, that the city of Bellevue requires a 6" brass nipple between copper plumbing and galvanized plumbing to keep the electrical connection intact. Does this "break" the electrolitic (sp.) or galvanic action between the two pipe metals, as well? snip..... Yes this is to avoid the electolitic action of the two metals. .....and what about the steel nipple on ALL hot water heaters that is connected to a flexible copper tube and then to the house system??? What gives there? snip..... 1. A lot of these nipples are internally and on end plastic coated to avoid electolitic action. 2. The flexable connectors themselves are insulated by plastic washers/bushings to prevent electrolitic action.
