Plumbing drain / vent help

3 posts in this topic

Hi guys,  plumbing newb here, like I really don't know much at all.  So anyway, I'm going to refinish my basement and am planning something but need to know how to do it and still meet code.  I have a stud wall with the plumbing drain / vents that was roughed in for a bathroom when the house was built.  What I'd like to do is add a wet bar sink on the other side of the wall from where the bathroom sink will be.  The rough-in has one T coming off of it.  Is there a way I could connect both sink drains to this T and still meet code?  I'll include a picture for reference.  I appreciate any and all help I can get.

P.S. - I'm in MN

Since nobody smarter than me has replied, here goes.  I think you would be ok. You just need a vent within so many feet of the drain.  Think of a kitchen double sink, or even a double sink and a dishwasher all going into the same drain, and only one vent.  

In my house, the sinks, the dishwasher, and the clothes washer all go into the same vertical drain, with the washer in the basement.

Are you talking your sanitary line or your vent line? That size will be sufficient for meeting code. i am assuming its either a 1-1/2 or 2" sanitary/vent line.. Both of which sizes would accommodate what you are looking to do.

A bar sink & lavatory is only 1 DFU "drain fixture unit" each your max you can do on an 1-1/2" line is 2 and on a 2" sanitary line it would be 6..

    • Three favorites at the moment.  By the time they upload, I may change my mind.
    • A few from Maplewood State Park on April 16th.  Non-professional, but they stood still long enough for me to get 'em.
    • You might be able to figure things out this week.  How big is your sump basket?  Is the  pump kicking in now?  Sit there for 15 minutes and count the number of times it cycles.  That should give you a decent idea on how much water is coming in.  Then figure out about how high the water has to go before it flows by gravity.  The spec for the pump will say something like that it can pump 2,000 gph at 10 feet of lift.  (the gph drops dramatically the higher it has to pump the water).  The answer to your specifics will give you an idea of how big of a pump you need.  If you match the size of the pump as close as possible to the amount of water your will face you can maximize the amount of time the battery backup will last.   Faced with this problem I took a standard boat sump pump and modified it so I could hook up a garden hose.  The I took an old shop extension cord and wired the pump so I could hook it up to a car in the garage.  So just prior to having Noah float by I could hook things up in the garage and be good to go for as long as I had gas in the car to pump up the battery.   Now that I am adult I bought a generator and wired the house to take care of things.
    • Inevitably at least twice each season I will leave the house, drive 45 minutes and walk some of my favorite grouse spots for hours and hours, seeing nothing.  Admitting defeat on that day, I will drive 45 minutes back home, only to find a covey of birds in the driveway...
    • Colonel E.H. Taylor Small Batch Maker's Maker's 46 Bulleit Glenmorangie Highland Single Malt   Copperwing Distillery in St. Louis Park has a nice smooth whiskey. Supposed to introduce a new bourbon in a couple weeks too.
    • Hey featherslayer, you gonna register that nice bird of yours pretty soon?
    • cool find!  sure looks like a Swainson's.  
    • Great info.   Thanks Steve!   Jim
    • Came across this hawk on Earth Day at the edge of town. I've been told dark morph Red-tail, dark morph Swainson's and dark morph Broa- winged. Anyway, it's a dark morph some kind of hawk.
