I'm new to this forum- thanks for any help in advance.
The attached image shows a DWV diagram for two bathrooms in a second story residence in NJ. I am concerned that the toilet farthest from the bldg drain may not pass inspection. Does UPC say the toilet has to connect to the stack directly? Any comments/advice is appreciated.

Fein...

The way you have this drawn up is very good! Only changes I would make would be to make sure you use only WYE fittings on ALL horizontal drain lines.

And don't forget to add a DANDY CLEAN OUT (also called a test tee) at the base of the stack.

Also, just be sure wet venting is allowed in your area as that is what you are doing here... some places won't allow this.

Otherwise... nice job!

Fein, nice visual !
Check with your local Building Dept. regarding wet venting. I work under UPC and we are not allowed to utilize this option.

I will check with Bldg dept re: wet vents. If I have room for wye fittings will do that too (or sweeps?). So no issues with the far toilet tying in at that location- great. Thanks very much.

Under my Code, we use:

1. Sweeps for transitions from vertical to horizontal (we call them Comby )
2. Y's + 45 bend for horizontal transitions only

Will this make Milo a happy camper?

Checked with local plumber- says wet venting is OK here (will ask bldg. dept anyway). And no S-T's horizontal.
Thanks again.

Good luck!

Actually, Tom, this rewised design would probably pass our Inspection. Only one thing in question would be the 2nd story toilet that is not vented.

Ps: love the drawing, anyway !

Sure it is Milo! It's tied into the vent stack with nothing discharging above it.
Go back and take a look. Cheers, Tom

Tom, I hear you - but still, and according our Code, even this toilet needs its own, dedicated, vent. Sorry, I don't make the Code, I just follow it.

Code develops based on previous failures. It is being updated continuously. It rewrites the previous version of the Code that proved to be inefficient. We have to constantly adapt to these changes, not to resists them. It is evolutionary process we all are part of. That's why we don't live in the trees and hunt zebras with stone axes for lunch any more...

Purpose of the Code is to protect homeowners, prevent health risks, and assure proper functionality of the system. It would be hard to believe that somebody would resist and refused to follow the Code. But some do just that...

It is natural for human being to question validity of orders, rules, and regulations. Our intelligence has the power to override these reflexes, recognize the benefits, and play by the rules...

Milo, what does your code call a vent through roof? If that's not a vent on the second story toilet then I been in the wrong trade for over 50 years and since there's nothing between the second floor potty and the outside world I would call that pretty dedicated. What would you call it? It's not that I wish to challenge UPC but they have restrictions that even you guys can't explain the reason for. Would you like to start another thread and explain away some for us ordinary folks? I'll be back in the mnorning to hear some dynamite explainations about UPC. Good night and rest well. Tom
