I put in a Wild Ride slide late last year, and finally plumbed it for this season. It has a valve that sticks up from the pool deck to turn on/off and adjust the flow.
I basically T-'d off the main 1 1/2" output line from the pump with a 1" line up to the slide valve (the slide itself has a 1" line and valve that came with it, hence the 1" size). I also installed a cut off valve for service ability.
The T for the slide is before the output port on the pool.
What's happening though is that when you turn on the slide valve, despite a great amount of flow and volume, the back pressure on the slide appers to be keeping the water from diverting to the slide, and all of the flow goes to the pool. I made a temporary cap for the output port on the pool, and that forces the water to the slide.
Clearly, I need to do some plumbing work. I could either install a valve on the pool port, or after the T to the slide to shut off that flow, but I'm hoping for a solution that my teens and wife can handle easily (without the risk of accidentally closing all of the valves at one time.)
Any suggestions on how to replumb?
