So built my own mash tun using the the below resource.
Last night i soaked everything in PBW and woke this morning to a washer that had severe oxidation on it.
Knowing that this is for the pre-boil wort, is this a problem? Should this be replaced? Will it cause any issues at all?
THanks for the help!
No link. Photo would help as well.
You do want to either replace or isolate that washer or it could impart enough iron into the wort to be tasted. If replacing, get at least 304 grade stainless, with a preference to 316.
You don’t have to replace though. You can coat the rusting metal with silicone seal rubber. Don’t worry about the heat rating since you aren’t placing the rubber under a physical stress. I do recommend using food-grade material and not using the heat-resistant type of the silicone seal. I’m pretty sure the heat-resistant stuff isn’t food-grade.
Only another week until Qatar!
sorry… link:
and i think the washers were zinc plated. that was the issue.
i just ordered a couple that are 300 Series Passivated Stainless Steel. Hopefully that solves the issue.
Yeah, that’s your issue. Go with stainless.
