Forgive my laymans description.
House was built in the 20's. Kitchen was added on in the 70's.
Sink runs through 11/2 (I think) copper through the wall down into the basement where it picks up a 1.5" horizontal run into the drain stack. Dishwasher is in an adjacent bay, but has its own 1.5" drain, whcih goes down and picks up the horizontal run. Dishwasher connects to the 'stack' in the cabinent via a 1", soldered to a 1.5" which wye's into the run. going up the dishwasher wye is another pipe into the wall which I am assuming is venting.
As you can see from the pictures, there is no loop/trap on the dishwasher side. at times in the summer (we moved in late summer) we would smell sewer, but assumed it was the garbage disposal which was pretty nasty. Then, the smell sort of went away. I need to fix the water supply for the dishwasher (incorrectly located in the cabinent), but when I pulled everything open I saw this drain that baffles me. This plus a mike holmes (dont laugh) episode where he mentioned not running dishwashers below traps as its a direct sewer vent, made me question this, and now I want to fix it.
So, my options are -1. rejigger the pipe in the cabinent, add some kind of a trap to prevent gas - I have never worked with copper that big and would be a little nervous about working with it.
2. Figure out how to cap off that drain, and run the discharge hose over to the disposal, or add a tailipe with a dishwasher inlet to the the other side of the sink (is there a prefered method?)
3. ????
Thanks in advance for all your advice, and sorry this is so long......
