So I have an 80 gallon Curtis horizontal tank that Im rebuilding a quincy 325 for. The inspection plate says 220 sides and 190 end caps which is way thicker than most tanks they make today. Id like to rehab it but I am concerned about the fact that there are no fittings on the bottom. Can I really effctively drain this thing regularly if all of the water is in the bottom and the drain would be on the sides? Any advice is appreciated thanks fellas
