[RedBird52]

Lots going on here.

Goal; Bathroom, Kitchen Sink, HVAC Drain

Approach;
- Wet vent Toilet + Bathroom Sink
- Horizintal [wet?] vent tub
- Vent Kitchen Sink Seperat
- Tie HVAC drain to trap of Kitchen Sink.

Funky stuff I did;
- Have to jog around a floor joist under the tub trap so Added some 45s

Thank you to all of the experts on this forum that have been teaching me how to do this!

Is the orientation of this Wye (in Blue) OK?

Your tub is conventionally dry vented; the vent take-off fitting would be better as a combo rather than a san-tee on the its back, and that may in fact be required (you'd have to check MA's code, it's different from both the UPC and the IPC).

The blue wye is fine, it could be a combo, and the two inlets should be at 2% slope.

Where condensate drains into a sink tailpiece I've usually seen a flexible connection as opposed to hard piped. In which case, depending on the condensate pipe diameter, you could still do the trap and tailpiece in the usual slip joint fittings by using a slip joint tailpiece wye.
