I was a farmer had many different plastic spray tanks but this metal spray tank and it's nozzle are vastly superior to any of the plastic ones . I've ever had and I've had at least eight different tanks before so this is a very very good one the quality is great the stem where it's sucking out the fluid from the tank is in the corner and it's has a little weld where it holds that stem in that position so it sucks out all of the fluid that's inside of the tank leaves very little residual
