Water slide plumbing

[Abw02]

I am planning on installing a slide to our concrete deck of our inground pool. We didn’t plumb a waterline when we built. However the slide will be right above a return inlet (1 of 3) into the pool. Is there anyway for me to connect tubing from the return jet to feed to water slide? I’d love to just connect when using the slide and disconnect when done.
We can alternatively connect a garden hose but the pool water is preferable. Also open to all other ideas. Thanks!

I doubt you will sufficient flow and pressure from one of three returns for the slide.

Are your returns threaded?

I wonder the same. I’m gonna try this attachment and rig it a bit and see if it works.
