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.

These lines are installed just below the joist and travels towards the back of the house.

The snake around the HVAC ducts.

And ultimately goes up to the target location. In this case, this is the 1st floor powder room. As you can see hot and cold water supply for the powder room vanity and the cold water to the toilet. Here you can already see one advantage of using these flexible PEX lines. The lines are routed directly with no cutting or splicing all the way from the source to the target location. This significantly reduces the point of potential failure due to weak joints.

This single line that goes to the south-east corner of the house is for hose bib at the back of the house.
