I broke down my first two hot water heaters today. My scrap yard said they paid $9.?? per hundred pounds?? So I let my curiosity win. One tank, possibly the older was wrapped with fiberglass on the inside so it went really well. The other was spray foamed...that one sucked. Should I just take the price cut and forget about breaking the tanks down? Also cut a pressure tank in half. My scrap yard said they didn't take any containers/tanks that weren't opened and I didn't know if that counted or not. Any thoughts or helpful hints?
