Blueboard, Pump Installed

Slow going, but going forward.  I have installed the XPS Styrofoam board into both boxes.  See below:

The installation was extremely straightforward, and the nails went in quite smoothly.  I have cut, painted and installed a piece of 3/4" plywood for the pump-side of the DWC.  This is to support the bulkhead fitting that will supply the pump, though I am beginning to wonder if the XPS would have performed sufficiently well.  Nailed to both the lower and upper horizontal members, it is surprisingly strong between them.

The pump shelf is now also finished and installed.  I affixed two triangular braces to the underside of the shelf, which stabilized it nicely.  The shelf is cut to fit only the pump, and achieves that.  I positioned it with hopefully enough room between the pump inlet and the DWC bulkhead fitting to allow for adjustment of the pipe, since it won't be an exact straight line.  I may yet need to get somewhat inventive with the plumbing in order to get the pipe position I need; this may be a series of elbows (ugh - no), or some heat-bending (yes!).

I have drilled the hole for the DWC bulkhead fitting, and test fit the fitting in the hole.  All is well, except that with the extra rubber o-ring, there are barely two full threads to screw the fitting nut on.  I may have to leave the o-ring off, which may indeed be recommended - need to go back and check the Green Acres instructions.

I will soon be placing the two bulkhead fittings for the GB.  I haven't yet decided where.  I must also determine the final plumbing configuration for the GB drain; one option is to run one drain to the other, and both down a pipe on the head-end of the DWC (farthest from the pump).  Another option is to drain directly in the middle of the GB, thus ensuring equally good flow from either siphon.  Yet another option is to put the main drop in or near the middle, but then pipe it around to the head-end, for better nutrient dispersion.

I'll be cutting the PVC for the actual siphons soon.  I must also rip and cut to length the boards that will top of the box edges, where the liner will be affixed.  It too must be painted, hopefully the last thing I need to paint.
