I am finishing the plumbing on my slide I had installed in the fall. It a Backyard series Dolphin slide. It requires 150 gpm, via two water fittings. Dolphin only supplies a stub of 2" pvc and a 2" to 1-1/2" reducer as water inlet fittings. Needless to say, I am concerned about (1) it does not attach securely to the slide and will move around, especially when the water is turned on and off, (2) 1-1/2" fitting seems like it will shoot the water too far down the slide (both fittings face down slide) at 150 gpm at almost 15 ft/s velocity, and (3) it just looks like ****.
Does anyone know of a proper fitting that will fit in a 2-1/2" opening and solve the problems above?
