So, While building my new brew pot I decided I wanted a pick up tube installed. Pieced everything together brewed a 5 gallon batch and saw a black film floating in the wort. I figured it might have been protein rest. Nothing else seemed odd. Transferred my wort into my glass carboy, pitched the yeast and it started fermenting within 24hrs. Today I was moving my gear around and noticed some rust on the 90* street elbow of my pick up tube. Turns out that 90* elbow is galvanized and not stainless steel. I guess I am dumping this batch and chalk it up as a loss .

That's not even galvanized its black steel it's not safe for drinking water it's a gas pipe fitting. It contains some lead not sure if it would ruin the batch with the little contact time. Even though it could be the cutting oil used to make the fitting giving you the film

Do you think the oil can ruin the batch? Should I just dump it and move on?

I wouldn't drink it with the oil in it but I've only done one batch so far I'm just going off what I know as a plumber. Your going to want to take those fittings out the bushing in the elbow is galvanized. Use lead free brass or copper if you get it from a home store don't know that they carry ss fittings like that. I'm using brass on my mash tun

I believe even brass and copper may be a bad idea for the boil pot I think they shouldn't go above 180f and also wort is acidic I believe which would cause some leaching

Just looking at that would make me dump it. Chalk it up as a learning experience.

My parents house had and still has a lead water pipe coming up from the basement. Most of the established municipalites use a large amount of lead in water mains..... Food for thought. If it doesnt taste right or has an oil slick on it I wouldnt touch it, but if it tastes fine................. In the mean time replace that elbow with food grade SS. For any metal part you want to wash it with dawn, boil it, wash it with dawn and boil it again before first use, as most if not all metals are cooled with oil during manufature.
