Here's a couple of completed pictures:
Cubsno1, would it be a horrible pain in the butt to ask what all connections you've used to hard plumb to the intex hoses?
I'm have the same skimmer, not installed yet, and looking into purchasing that exact same SWG/sand pump, and have the same hoses with the Intex plungers on my pool already. The pool is primarily my responsibility, and the hubby is not really good at designing/fitting, etc. but if I have all the right parts he can seal/cement them together for me...your setup is what I was picturing in my mind for us when I install my Hayward skimmer! I plan on replacing the original Intex pool inlet with a Hayward one, and changing the original outlet to another inlet with eyeball, as long as I can install the ball valves like you have....so I'll have 2 returns and then the skimmer/outlet. Any details would be appreciated (and probably save me multiple trips to the hardware store!!)
Edited to add: I have pretty much NO experience with PVC or connections, but I do know you paint the primer and cement stuff to seal the connection together. That's about it lol
