    Venting for a basement utility sink

    Hello,

    I have question for you guys - I'm looking to put in a utility sink in my basement and use a gray water pump to eject the sink contents to our septic.

    The difficulty I am having is finding a way to vent the sink in an acceptable fashion without tearing apart walls in our upstairs living area. I'm seeing a number of different opinions on this subject and am wondering your thoughts.

    I had considered a few options (including tying both the drain and the vent into the horizontal 2" PVC in the picture OR adding a 4 x 4 x 1-1/2" WYE to where the current cleanout is and putting a new cleanout behind that.). Orange box guy told me to just use a studor vent.

    Any advice you guys might have would be greatly appreciated.

    Thanks,
    Monk (in NH)

    Why can't I reply with a quote like the rest of you seem to do? I hit quote button,but it asks me to log in,when I am already logged on. Then when I try to log on again it just brings me back to the log on screen. The only way it seems I can post in threads is if I go to the beginning of the thread and hit the post button there.

So start peeling that insulation down and look for your future vent.
    rmurf that's Mass code where plumbing is still plumbing and plumbers are still plumbers. The IPC dropped the future vent requirement over 10 years ago.

    Would this apply to a house built in 2000 in unincorporated Arapahoe County, Colorado?
    Would a "future vent connection" look like an inverted Wye with piece of capped pipe descending from it?
    Does "drip connected" mean something my boss putogether?
    Thank you.

    When was the last time you ran across a pneumatic ejector?

    I thought ejector vents had to terminate separately from the rest of the plumbing system. Has THAT changed too?
    Here in Mn if the sewage ejector pump is pneumatically operated the vent must run separately through the roof, if the ejector is electrically powered the vent may be joined to the rest of the waste and vent system. Mn has it's own State plumbing code but it's similar to the rest of them.

    I've never seen a pneumatically operated sewage ejector.

    The tank vent vents the tank not the fixture. The elbows are fine.

    Did you look for a future vent?

    I just thought the 3 1/4 bends right out the top of the basin was pretty convoluted, and definitely not high enough to go horizontal yet...

    In Mn, which uses the Minnesota Plumbing Code, the vent would have to be 6" above the flood level rim of the highest fixture in that branch interval. (Assuming the laundry tub is the tallest fixture in the basement, the vent would have to be 6" above that before it could be run flat.

    No mechanical vents are allowed. Period. Vents must terminate in open air.

    Perhaps the code is different where you are.

    Strange, I don't think that installation would pass inspection where I come from.
