Hey I have a problem. Just noticed this morning that there was a sewage back flow from the sewage drain in my front yard. Called the plumber and he snaked it out from the front yard. He deemed it good. But I noticed now there seems to be small amounts of clear liquid seeping from the title baseboards in my Kitchen. It is only one wall and is only trace amounts, but left unattended can form a small puddle. Is this related to the black up or something else entirely. Thanks

If your sink drains OK then you have a different problem. How old's your house? It sounds like you have a leak in the horizontal drain line in the wall. To test, dry the area up and fill the sink up with water and let it drain out. If a puddle appears let me know and we'll start a repair. Good luck, Tom
