Hello,
First, let me say this is a great site with lot of knowledgeable people, it definitely helped me so far !
I'm planning to relocate a bathroom in my house, enlarging it and adding a bathtub and a shower. This is a one storey house, and the basement under the bathroom will never get finished as this is the basement entrance and wood bin. Attic over bathroom isnt finished either.
I drew a couple sketches of what the dwv system could look like, trying to respect the plumbing code (NPC), and would like to know if I'm heading in a wall before going any further... Please help me make this system better and up to code.
Somes remarks first:
- the main stack is around 4 foot from the end of the wall at top left. I need to offset it and will reconnect the main vent in the attic.
- every horizontal run will be sloped at 1/4" per foot.
- the bathtub and shower traps arms lenghts are not indicated, but I will keep them under the max lenght to avoid partial p-trap.
- the bathtub and shower traps are wet vented from lavatorys.
- every fitting on the horizontal run are wye or 45 degree bends.
- the orientation of the tub trap is wrong in the drawing.
- lavs vents will be in an exterior wall, but the drains will go throught the floor. the vent will take of a sanitary tee and will offset at no more than 45 degrees to reach the wall. (is this ok?)
- i want to avoid piercing joists as much as possible, but the tub trap is in the way of the exterior door if below joists, and I read many times than the closer the trap to the fixture, the better it will be.
- Co on the drawing is a Cleanout.
- The dimensions and proportions of the room are corrects.
Here is the drawing :
And here is the conceptual plan :
If some details are missing I will provide them promptly.
This job will be inspected so I definitely want to get it right.
Thanks a lot for your time !
