HVAC rough in day 8

For the ductless side of the HVAC, the work continues on getting all the hangers made and installed for the rest of the three ceiling cassettes.

This is the unit on the 2nd floor on the west side. The hangers are completed. The cassette unit will not be installed because the roof needs to be spray foamed first.

This is inside the 2nd floor bedroom. The 2×6 bracing is installed, the hanger is not there yet. The units here will also not be installed so that the roof can be spray foamed first.

Electrical rough in

Abdul B Molla from Advanced Electrical Company started doing electrical rough in work today.

There are a few things that are different about this house. First is that a GFI outlet is installed near every toilet. This is so that I can install electrical bidet seats on the toilets. Here you can see the outlet in the basement bathroom.

Plumbing rough in day 5

Plumbing works continues today. With the drain pretty much finished, water supply lines are being laid out today.

I choose to have a manifold system to distribute the hot/cold water supply. So there are a lot of lines will need to be run from the mechanical room to the target location.We are looking at laundry room, basement washroom, 1st floor powder room, 1st floor kitchen, 2nd floor bathroom, and 2 hose bib one at the back of the house and one on the roof top terrace. So that’s 5 pair of hot/cold lines and 2 cold water only line that needs to be run.

Here we see the first 3 lines being laid. These are the hot/cold water lines for the 1st floor powder room, and the cold water to the hose bib at the back of the house. The supply lines are PEX or (cross-linked polyethylene) lines, so they are flexible. With the tight space I have in this house, it would have been super labour intensive to run copper pipes.

Plumbing rough in day 4

Alex and Anthony from AV Mechanical is here to fix the roof drain that was temporary re-routed because of the HVAC ducts.

Back on September 23rd, the roof drain was re-route like this to allow the HVAC ducts to pass to the mechanical room. However this is not going to work because this means a lost of 3″ in the laundry room’s already low ceiling. What the HVAC contractor suggested was to route the roof drain all the way around the laundry room on the wall.
