Bathroom conversion

[Ottawa97tj]

So, previous owners converted 2 bathrooms on the top floor to one main bathroom, due to some water damage I needed to gut the washroom, since it is gutted and I don't trust the plumbing I figured I would convert it back into two bathrooms, I have been trying to figure out how the builder would have plumbed it. In the run there would be 2 of each a sink toilet and tub. I am at home so I don't have access to any fancy drawing software but this is what I was able to come up with.



Once the runs goes horizontal there is a 3 inch San Tee that is the main vent stack that goes through the roof, attached with a San Tee to this stack above the horizontal run is a 2 inch Sink waste. On the continuing on the horizontal run is a 3 Inch Y that is for the first toilet ( no vent except the main stack) after the toilet Y there is another Y for the tub this line 2 inch line is vented. After the tub Y there is another Y that is used for the second washroom Tub and Sink which is also vented. After that Y there is a San Tee that goes to a vent for the second toilet, At the end of the horizontal run is the toilet.

Does this make sense. I will post some pics to hopefully help describe this better. Also if you require more pics let me know and I can take some snaps

Here are some pictures



Once the runs goes horizontal there is a 3 inch San Tee that is the main vent stack that goes through the roof, attached with a San Tee to this stack above the horizontal run is a 1.5 inch Sink waste. On the continuing on the horizontal run is a 3 Inch Y that is for the first toilet ( no vent except the main stack)



after the toilet Y there is another Y for the tub this line 1.5 inch line is vented.



After the tub Y there is another Y that is used for the second washroom Tub and Sink which is also vented.



After that Y there is a San Tee that goes to a vent for the second toilet, At the end of the horizontal run is the toilet.

Apologize if this is confusing let me know if there is something I could do to clarify
