the only problem I had with the ball valve was that it was so dang hard for me to turn. I ended up keeping a pair of channel locks by the pool to help me turn it.Yes that was the plan. The tub already has a good slope to it so that will help. I just wanted to have a large enough drain and valve so I would not have any issues with poo and gunk when draining it. 5/8" or even 3/4" garden hose I think would cause an issue. That's why I went with 2"!
