I'm done with TSC. I have bought 2 5 gal. metal waterers and they both leaked. I even called the company and they sent me a new one. The guy on the phone said he personally inspected it and no leaks. Yah right. It leaked 5 gallons of water in 2 hours. And I know for a fact that its level. Now i wanted a plastic one but my Dh said no b/c of heater. So i filled that baby full of gorilla glue on the top seals that never touch the water. Presto no more leaks, it is an ugly thing though.
