: Terry,

: I would like to relocate a laundry room from the first floor to the basement. The main drain stack in the basement is accessible for draining. Other than venting up through the house and through the roof, what are accepable options for venting a standard laundry tub and/or washing machine drain hose? John

John,
Checking your local codes may allow for an air emitter valve like the Studor.
