Co2 and copper
Anyone have any first-hand knowledge of adverse reactions from running co2 through type M or L copper pipe? My gas supplier says no ( and has a compatability chart to back it up). However, I recall from our start-up the coca cola boys required stainless or food grade pvc for their product line and my plumber thinks it's not a good idea based on his experience with the food-side.
I am looking to run about 100 feet of 3/4" cu pipe from my bulk co2 tank to my new fermentation room.
