So I bit the bullet and bought the 15 gallon boilermaker. It came with the sight glass already attached and no wort was getting into the glass. I took it apart and noticed that the bottom bolt isn't hollow so nothing can get through while the top is hollow. So is it upside down or did i get a defective bolt? Ie is the hollowed out one supposed to go on the bottom and the other one on the top? THanks in advance
