Mmm instead of splitting the drains into each filter sock the drain dumps in next to them and the socks work more like a filter floss. Actually not bad, then as they clog water will divert around them?
You could try it that way it may work really well. Alternatively perhaps tee off the drain after it enters the sump and divert the flow directly into each sock? Don’t glue the PVC tee or fittings then when you want to change the socks, pop off the Tee and access the socks easier.
Honestly, I might set it up how it is and see how it goes.
