I'd use
a Gorton #1 or Hoffman #75.
What vent do you have on the other main?All Steamed Up, Inc.

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.0 -
You're right, it's not
and you can vent that main with the same model vent.All Steamed Up, Inc.

thanks
which is better the gorton 1 or the hoffman 750 -
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.All Steamed Up, Inc.

would the gorton#2 be beneficial or would it be overkill. thanksY0 -
On such a short main
it would be more than needed.All Steamed Up, Inc.
