return pump plumbed 1" true union ball valve into header with 1/2 gates to run my reactors. then a check valve.
1" come up to a tee then 1" gate valves into my line lock returns. put a few unions in so i can dissasemble it if needed.
1 1/2 drain line done just with 2 45s. left the rest to do when there water in the tank so i can test for sound differances.
