Man developing the basement is taking forever! I finally had time to put in the floor drain, build the sump stand, and silicone the overflow back on. I won't likely get a chance to plumb it before I go back to work but we shall see what happens on monday!
Rigging to hold over flow in place while silicone dried.
General arrangement. The floor drain will have the water change valve and emergency overflow plumbed directly to it.
I will try to describe the flow of water through the sumps. You can see the primary frag chamber top left, return pump chamber top middle, and overflow top right. The skimmer chamber is bottom right, filter basket chamber bottom middle, return pump chamber bottom left, refugium bottom far left.
The refugium will be fed off a manifold powered by the lower sumps return pump. The manifold will also feed a couple reactors for bio pellets and GFO.
Slowly but surely it's coming together.
