Ha dont get me started,i wish i would have looked into more of this stuff before the pool got built so it was done right with no questions, anyways heres the answers to your questions and im going to put pics on also,
1- YES it is on its own loop, (waterfall-slide)
2-size suction pipe- 2 1/2"
3- the run from the pool is about 25ft i would say
4- yes i want to be able to run the slide and waterfall together, hes suppose to be putting on a valve actuator so you can turn one or both on and ajust the water pressure .
5- flow rate required for the waterfall and slide i have no idea and i know he has no idea, i would think i could always turn it down with the valves, so lets shoot for the most we can get out of it, hopefully the pics come out and you can see how big the waterfall is and you can get an idea how much water needs to come off , i really want it to gush
picture 1 shows in the far left where the equipment is and on the right where the waterfall is
picture 2 shows the front of the waterfall that i am hoping to have a big wall of water come off
picture 3 is a closeup of the way he has the pump and plumbing for the waterfall
