So last year when I rebuilt my kegs I bought some replacement pressure relief valves. I think from Chi-company, but maybe whichever online place I ordered from that day, so I'm not pointing fingers.
Today I'm cleaning my kegs and pulled these two out. One completely rusted, and one just fine.
So who grabbed the non-stainless piece of metal and put it in the lathe? I don't think a hose down with diluted starsan would do it, nor would a splash of oxy/pbw. So what gives?
Nothing can be done but trashing it, so just check your PRV's when you get them!
