When I started the project I used floorplanner.com to come up with a floorplan layout that my wife and I liked. That one lets you layout furniture and do design stuff really easily and is free. But, then I wanted to figure out the framing details so I started to play around with the program I am...

I did, but wanted to stay away from engineered building materials since COVID was causing some shortages and supply chain delays when I began building. Dimensional lumber was readily available (at an inflated price unfortunately). I see what you mean now, instead of coming across first, come...

Yup, I am the owner, plumber, insulation contractor, etc. so I have to balance the cost and install complexity with a good functioning system. We're planning to add an addition to the east side down the road, so I put in a wye where the kitchen line ties in and will keep that branch at 3" so we...

That'd save drilling 2 joists but I think it would push the main 3" pipe down a little further towards the ground, plus leaves more piping exposed if I do not box below the joists. Yup, I like simple. Our code here in Ontario only allows a 2.75" hole drilled in a 2x12. Plus I am near the...

Tucked the washer drain up as well now. Can it wye into the horizontal main drain like that?

There won't be a basement below, the closest I would get would be boxing in the plumbing with PT plywood and insulating it. So, ideally the washing machine would be tucked up in a joist bay but then cannot vent after the WC unless I drill 2 joists. and use a long sweep 90 instead of the 45 that...

Figured out how to do the 45s so the bends are pretty accurate now, just need to figure out the piping sizes which should be pretty simple with only the WC wet venting... and then make my parts list.

This is a great consolidation of examples... love it

This all makes sense, thanks for the help to interpret and clarify these points. Now I need to figure out how to draw 45s and then what order to assemble everything so I don't get stuck. Thanks so much for all the guidance!

Okay, makes sense and keeps the shower trap up high. It would be like this but with 45s bringing the shower vent / main stack and kitchen drain down below the joists. For the washer drain, why is it not prohibited to bring it in down stream of the WC? Is it because the portion downstream of...

The floor joists are 2x12s so the actual dimensions are 1.5" x 11.25". The rim joist sits directly over the outside ply of the 4-ply 2x12 beam. So, on the inside of the rim joist, there are 3 plys worth of 2x12 beam to get around (3 x 1.5" = 4.5") So using the outside sheathing as a reference...

A clothes washer is listed as 2 fixture units by our code, requiring a 2" trap. A kitchen sink (as shown in the code example) is 1.5 fixture units. So, I think the clothes washer is an acceptable substitute for the kitchen sink which was used in the code example, but I could not run both into...

The double sanitary tee is available here and mentioned in Canadian code. The 3x3x3 tee with 2" side inlet is also available but I don't see reference to it in our code. For the main stack where the shower vents, 2 90s will keep it up higher in the floor joist so in that application I think it...

I had a feeling... lol This gets rid of one more hole thru the joists. The double wye would work here (likely better to smooth the flow of solids), with this configuration I have enough room vertically beneath the floor joists for that to work. I posted the wet venting rules from the...

That is a good background on the venting, thank you. I reworked the design based on the previous suggestions and was able to make it more efficient. The shower vents thru the main stack instead of separately, the WC now wet vents thru the lav, and the kitchen and washer drains run parallel...
