Our sweeneys have flooded on more than one occassion, and they all lived to sling pellets again. My guess is that you'll have the same luck with the TH feeder.
Like mmorgan, we've even had to clean rotten, caked aquamax out of a feeder with a pressure washer. I'm thinking that car wash probably still has a "wanted" poster up with my mug on it.
"Only after sorrow's hand has bowed your head will life become truly real to you; then you will acquire the noble spirituality which intensifies the reality of life. I go to an all-powerful God. Beyond that I have no knowledge--no fear--only faith."
