    Basement shower drain vent??
    I am installing a basement shower which was stubbed when the floor was poured.

    A P trap is in the floor about 3' from the main horizontal sanitary line which goes out to the septic. I can see no vent lines and wonder if I need to vent the shower.

    If I do need to vent it, the vent needs to be between the trap and the sanitary line, correct? I also have no vent for the sink which was also stubbed in.
    If I need to vent these two appliances, may I vent up and out through a 2 in line terminating under a deck or do I need to tie into the attic stack?

    Thanks in advance,

    Hi Dave,

    Let's not get hasty. Are there any other vented fixtures in the basement. Utility sink? Washer? If there is then the shower's probably wet-vented back to the drain of one of them. As a rule we wet vent our tub and shower rough ins. If there isn't any way to wet vent it then we stub up a vent so the home owner doesn't have to break up cement. Let me know. Tom
