How is this even possible? I've used this 7-8 times with up to a 50# grain bed. Noticed last brew is was slightly bent. Today was a brew day from hell. Kept getting a stuck sparge. I have a RIMS with a March pump. Grain was clogging up the system. We dumped the grain out and pulled out the false bottom. This is what we saw!!! It was not damaged when we put it in the pot. I can't for the life of me figure out how it got this damaged. I don't think I could damage it this bad if on stood on it!!!
