Hi guys, I had disconnected my black flex irrigation pipe from my back flow preventer since I am on well water now for irrigation. Where I took the gray plastic fitting out I'm looking to put a boiler drain of some sort there. I can't find a drain that has the 1" male threads I need so the guy at Home Depot gave me a 3/4" brass boiler drain with a 1"-3/4" galvanized coupler. Can these two metals come in contact? I've read it will create corrosion issues but I can't find the coupler in brass. If the back flow is copper that brings the total to 3 different metal, can I expect any sort of reaction? Thanks
