    Basement Bathroom Vent
    I am finishing my basement. It has roughed-in plumbing under the slab for a bathtub, sink and toilet tied to pit for a sewage ejector pump to pump up to the municipal sewer. There is a 2" capped PVC pipe protruding from the first floor bathroom, which is directly above this bathroom. I am assuming this is the vent. How do I vent this new bathroom?

    Not so fast Chauncy,

    If the capped pipe in the bathroom is coming out of the holding tank then it's a dedicated vent to the roof. No other vent may be connected to it.
    Your bathroom group will be vented by the lavatory. This vent may be revented back into a existing house vent but under no circumstances can you connect back to the holding tank vent. You will have two vents coming out of the basement group. Good luck, Tom

    Speedball1,

    The capped pipe is from the existing house vent. The holding tank has a separate vent as you mentioned.

    The sink (vanity) will tie in to the house vent. Does the tub also need to be vented. What is wet venting?

    Very good, Sounds like you're on top of everything. The tub will be wetvented by the lavatory.
    Wet venting occurs when you tie the tub drain into the lavatory drain.
    When you drain the tub it will vent through the lavatory drain and out the vent. Hence, the name"wet vent".

    Or, to say it in a nutshell: a "wet-vent" is a pipe that serves as a drain for one fixture, and as a vent for another fixture.

    Does it matter what order the bathroom fixtures are plumbed in to assure proper venting? The bathroom is laid out from left to right with the tub, then toilet, then vanity, with the tank being approximately 30 feet away (furthest right).

    Hey Chauncy,
    It doesn't make much difference how the fixtures are configured as long as the lavatory's vented and the tub drains into the lav drain. Good luck, Tom
