Can I use this 3" pipe?


Hello!

I have been trying to figure out the DWV done by the previous owner. Can I use the pipe, yellow arrow, in the photo for a utility sink? More info and pictures of the vent can be found here. This is the main soil stack that leads out to septic system. In the other post this terminates through the roof. Does this remotely qualify as a wet vent if I put a fixture here? Its almost where I would need it to be to install this.

My only other option is to try a Hartell LTA and connect it to pipe with red arrow...but it is on the wrong side. There was a utility sink here I took out that drained into the sump, which you cannot do...

Is there a way you could put a vent on the 3"?. What you propose to do (if I 'm following you) is an illegal wet vent. You cannot wet more than 1 floor. There are other wet vent violations there as well.

I am swapping the toilet and the sink in the hall bath that will fix that bathrooms violations. There are no fixtures on the second floor. Blue arrow is master toilet which as far as I can tell has a vent. Laundry is going to be removed. New hall bath shower will get a vent. I am probably going to drop the ceiling in the hall bath 4"-6" to make it easier to run vent. Also, going to make a custom shower so can bring vent for shower straight up and tie all together.

Not familiar with a Hartell LTA but it looks like it would work there.

The Hartell LTA install went very well and works great! See first pic.

However after regenerating the softener and the iron filter I a going to have to use the pipe with the yellow arrow in the original post. I am going to have to drain to gravity. During the regeneration there are periods of heavy water flow which forces the pump to run almost 6 minutes non-stop followed by cycling for close to an hour. This cannot be good for the pump and I am sure its days are numbered.

I found the Kohler Sudbury utility sink with 3" drain which uses part K-6673. http://www.us.kohler.com/onlinecatal...sp?item=339702 the PVC pipe is only 1.25 inches too high so can pour a thin concrete pad or build something solid to bring this up to pipe. Can I connect PVC to this iron P-trap? I'm going to need a 2" or larger drain.

Will using a 3" sanitary tee with vent to the right work? Can I use a long sweep and go to roof or do I need to use another sanitary tee? The P-trap comes with a clean out. See pic.
