Update time, got the overflow plumbing cut and peiced together, haven't glued it yet, changed a few things due to budget constraints. Should still work well.
As you can see instead of using the 90's out of the overflow bulkhead I switched to T's so I could run a verticle pipe with an open end to cut down on noise and allow air in.
Parts list:
3/4" pipe cuts: 2 x 2", 2 x 3", 2 x 5", 2 x 8.5"
1.25" pipe cuts: 2 x 13"
2 x 3/4 T's
2 x 3/4 ball valves
2 x 3/4 to 1.25" 90's
1 x 1.25" T
All the plumbing parts ran me roughly 25 bucks at Lowes. Still have to determine the length that's going to run from the center T to the W/D.
Comments and suggestions welcome as always.
