    I'd use

    a Gorton #1 or Hoffman #75.



    What vent do you have on the other main?

    no vent

    Thanks. i don't think there is a vent on the 1 1/2" main (basement is finished so hard to tell). the plan is to add a tee at the end of the dry return (the end of the main is not accessible). on the 2" main there is a Hoffman 45 which according to Hoffman's web site is not a main vent.

    You're right, it's not

    and you can vent that main with the same model vent.

    They're about the same

    but the 75 is typically more expensive. Also it's taller, which may be a factor if your height is limited.

    On such a short main

    it would be more than needed.
