Leak In Kitchen Drain Pipe!

[Cyberwolf]

Hello.......I have a leak in my kitchen drain pipe somewhere after the pipe goes into the wall under the sink. I suspect the leak is in the first couple feet of pipe somewhere near this point because I notice a few drops of water dripping down from ABOVE a basement window located directly under the kitchen sink area. The water also seems to be running down the inside of the basement wall and collects in one corner of the basement which has caused mold and ruined the carpet in one corner. More water seems to collect in the corner and drips from the basement window immediately after we run the dishwasher. There is a small water stain on the basement ceiling in this area but I have never noticed it being wet there before. I checked all pipes directly around the dishwasher and under the sink and all seem dry. When we do NOT run the dishwasher things dry up very quickly.

The drain pipe is the black plastic type and the house is about 8 years old.

Any advice on tackling this problem would be greatly appreciated!

Thanks,

Jim

Well.......I guess I will start cutting a hole in the basement ceiling to see what I find. I'm not sure what to do.......maybe I'll just call a plumber but I really can't afford that.

Okay........I cut a hole in the wall behind the kitchen sink and found the leak at the bottom of a "T" fitting where the drain connects to a vent pipe going up to the roof.

Can anybody please tell me how I can fix this leak? As you can see there is a 45 degree elbow clued into the line very close to the top of the "T" which seems to complicate the situation a bit.

Any advice would be highly appreciated......I'm a poor home owner who cannot afford to hire expensive plumbers......please, can anybody help me? I'm happy to do the work but I just don't know the tricks of the trade

The easiest way would be to cut out the elbows and redo the joints.

You might be able to cut out just the elbow to the vent stack and use a rubber Y boot available at any big hardware store.
I think you can also get a product that you paint onto the area to seal a bad joint. I have never used it and never would but I've seen it used with some success.

Thanks Pushkins.......I also was thinking about cutting out the tee and glueing in a new one but then all three pipes would be too short for the new tee.

Looks like the best bet will be to use some sort of soft rubber sleeve, cut the pipe at the bottom of the tee, slip the sleeve over the bottom end of the tee as well as the pipe going down and clamp both ends?

before you go bonkers about cutting out the T-Y see if you can find some ABS cement with a plastic filler in it. I know they make a type that is blue or purple in color for PVC and it's really thick because of the suspended solids in it.
