      Ps
      The purple pvc will attach to the inside back wall of the stand horizontally with the Clik pieces(4)
      The 90 elbow on the end will connect to a Cor pump

      Opinion

      Do you need the 90s or can you T straight up?

      Swap the 90's with 2x 45's, throw that check valve in the trash
      ...it will fail eventually

      I do not put any faith in check valves... in fact I do not use them when plumbing tanks unless absolutely necessary.

      Simply angle the interior locline up near the water surface and avoid the issue of back-draining altogether.

      Thanks for your input
      I will do that
      I think I will also have enough capacity in the sump as well

      Is the placement of the ball valve after the tee correct?

      I’m a fan of check valves but ones over a sump that can handle the water either way. I also oversize the check valve and reduce to the return size (ie 1 1/2” check on a 1 1/4” return)

      Ok
      45s probably better
      Was going use 90s as support since they would “sit” on the back panel cutout but the Clik should work fine

      I did that
      It’s a 1 inch check with a 3/4 reducer on top of the union
      Was gonna run 3/4 flex pvc to the 3/4 elbow on the rear panel bulkheads

      If your intention is to control the amount of flow going to one return rather than the other, then yes.

      But if your intention is to be able to halt all water flow, or, to be able to disconnect the tank & plumbing from the stand & plumbing, then the ballvalve is placed incorrectly. It should be placed below BOTH returns, not just one. According to how the picture is oriented, you would need to move it to the left of the left return line.

      My intention is to try to equalize the flow to the 2 returns with the call valve

      Then technically you would have (2) ballvalves.. one on each line to fine-tune each line individually.

      ....however, in all reality what you have wil work beautifully. There is no reason / need to have both lines pumping the exact same. The valves current placement will give you some good enough control over which side gets what percentage of the total flow.

      All good!
