Hey guys,
I'm getting close to having my inspection (Alberta, Canada) for the below-grade plumbing and I'd like to get some of you fine folks to double-check my work. Some of it (the parts that are already in use) are cemented, but some of what you see is just dry-fitted.
There's a lot going on in a pretty small space. There will be a wall almost bisecting the picture. Bathroom on right, Laundry / Furnace room on left.
Some comments:
- Backflow preventer is at where the drain exits the house.
- There is a roughly 1/4"/ft slope throughout the horizontal.
- The vertical stack, the vent at the shower drain and the stub for the basement kitchen will all be inside the future 2x6 wall, with access panels to the cleanouts.
- The tub drain and overflow are not at the right height...it will end up much closer to the bottom of the picture once it is trimmed.
- The 1 1/2" vent are going to be attached to the main stack above the overflow level upstairs.
- All the fixtures (except for the toilet) have p-traps.
- The center of the toilet flange will be 12" from the finished wall and the tub drain will be setup for a 60" x 30" tub.
One of my concerns is the 180 degree turn for some of the pipes. I know it's not idea, but is it strictly forbidden, or does it depend on the inspector/locale?
The other concern is venting. I hope I have adequate venting, but I could be wrong. I'm not 100% clear on those requirements. The basement kitchen line will have it's own vent closer to the end.
Anything I should change or consider before cementing up the rest and booking an inspection? Thanks in advance.
Here's the same picture without labels and also another.
