lol,,,not very much after that run up stairs !!!! ,, i see a Hammerhead or a Cuda in the future , its a far run to the tank for any pump. this Dolphin is only 3600 gph , i am going to need a good bit more . with these pipes as you know you, you can run a great deal of water through them , they are that adjustable . its right around 1200 gph at the tank.
