registers

One small oversight in ductwork planning was the geometry of the underfloor space at the register outlets. I planned on having the ductwork bend upward and come straight up to the register outlets along the perimeter walls. I failed to realize the part of the floor adjacent to the exterior walls is actually located over the foundation wall, and the ductwork needed to come in at an angle.


I have already purchased the round pipe to 2-1/4x12 rectangular adapters, shown in purple. These are straight fittings, so the input round pipe and output rectangular pipe are in a straight line. I now need to fabricate the rectangular bends, shown in red, to connect from my supply lines to the baseboard registers. I'm also considering making the red bends curved rather than a sharp angle. If it can be fabricated without much trouble, it may improve airflow a bit.

The floorjoist on the left, shown with a single diagonal line, is the closest joist to a register outlet in the whole house, it's only at one location. I put it there to be sure my configuration would work at this tightest spot.

the status of things

I have a few things on my plate currently.

I need to finalize the details of the master bath shower and acquire the necessary materials before I begin working on it. This includes the waterproof shower pan at the floor and the walls, and the details up to the tile. I think I will use a PVC liner for the pan and redgard over concrete backerboard on the walls.

I need to install boxes & run all the low voltage lines - tv/internet/phone. I'm going to run RG6 quadshield for the cable and cat6 for ethernet/phone. The RG6 lines run from the boxes to a splitter in the crawl, and the cat6 lines run from the boxes to a central box in the linen closet. An ethernet switch can go in the closet to merge all the cat6 lines. Alternatively, an internet phone or hardline phone can come into the closet, then feed onto the cat6 lines. The cat6 terminations in the rooms can either be ethernet jacks (from a switch) or can be wired to telephone jacks (phone). The system will be easily changeable once the house is done, so a mix of ethernet & telephone can be done as well. The lines & jacks are actually pretty cheap if you buy from the right places.
*edit* To clarify, I'm installing a pair of 8P8C jacks on each phone/net plate, one white & one grey. They come into the linen closet, where they can be connected to an ethernet switch or wired to telephone. A standard phone line - 6P2C, 6P4C, or 6P6C plug can go into the 8P8C jack in the wall, so to change one or both of the white/grey jacks from phone to ethernet only requires changing what's connected to that color jack in the linen closet. Well, that's the plan. I used some info from this page to come up with the scheme.

I need to finish cutting holes for the hvac supply registers in the floor. Currently, I have cut four holes, so I have six more to go. I don't plan on starting to fabricate the ductwork until everything else is ready to go.

Everything else would include running the range hood vent duct through the roof, finishing the shower, finishing low voltage wiring, connecting up the dryer duct, running the main water supply from the entrance valve to the water heater and manifold, ..

I think that covers it. Some big things outside of that would be building the two entrance decks and running the water & sewer lines out to the street. I'm not going to run those lines until my plumbing inspection, which is after the shower pan is complete. I still haven't decided on the timing for the decks yet. I'd love to put them up soon, but I know it's easy to back up the pickup truck to the front door for loading/unloading large items currently, and the deck may make that more difficult..
