Plumbing mixing station using spa flex??

[MattL22]

So I've been brain storming how I'm gonna set up a mixing station for my 225 for a few months I have 2/ 55 gal barrels I purchased and plan on using my old external return to pump the water around the perimeter of my basement using spa flex thorough 2 closets into my sump located in a 3rd closet and a separate line for fresh water into my top off container!
I wanna use PVC and uniseals too plumb the 2 barrels too my pump

So question is how to do it?
Because I wanna get the materials together ASAP otherwise ill never build this thing!!!
How do I pipe this out so I can pump salt water through 1 run into my sump then close / open few valves and pump fresh rodi water into my top off container??
Is there special fitting that attaches spaflex too regular PVC??
Thanks for your help any pictures / comments would be greatly appreciated!!

Spa flex will glue to regular PVC elbows couplings etc. with regular PVC cement. Be sure to use a primer/cleaner on the fittings prior to glueing.

Some hardware stores carry it also you have to check but HD and Low_s has it.
Show some pics when you build it.

Here are two pics of spa-flex with PVC fittings. I use both rigid and flex in my set ups, one offers strength and stability, the other flexibility in tight spaces. Chiller connected with unions to spa-flex. I have found spa flex at homedepot and lowes although not always and not all diameters. Comes in 1/2",3/4",1,2", OD. A plumbing place that deals with jacuzzis and spas would be best bet.
