We had a plumber come out and unclog a drain in the bathroom sink on the main floor of our rambler house. There were no other clogged drains in our house. A few hours after the plumber left, I pulled the shower curtain back and I discovered our bathtub was full of black water and some kind of black sediment or something. We noticed that when running the water in the sink, the water was backing up into the bat tub. What is happening? Can we fix this or do we need a plumber again?

How full are we talking? 1/4 or 1/2 more less??? Also how far away is the sink from the bathtub drain? I think that if it was just the sink line that was clogged and he ran a snake or something down there he couldve just pushed the blockage farther down the line(just past the tub drain) and then left it there. If this was the case when he ran the water at the sink to see if it was still clogged the blockage would stop the water and it would then flow up the tub drain.

Im not sure if that will make sense to you but its as clear as I could put it.

Thanks for your response. Your explanation makes sense. The bathtub was roughly 1/4 more or less full. The two drains might be about 5 or 6 feet apart on the surface. I don't know about the distance in the wall. I guess the bottom line is that the plumber should have kept running the snake. Besides checking all drains to make sure there are no clogs anywhere else, is there something else we should be aware of the next time?

Hey no problem thats why everyone on here right :) Well Id assume you have a main cleanout somewhere in your sewer line. Rule of thumb when I was doing the plumbing thing was that if there was a clogged line we would snake and then open the clean-out and run the water to see what kind of flow we got and if it was still poor we would snake further and repeat that process until we got it.

Does your house have a basement or crawlspace? It is generally close to where your sewer line leaves the house. I'll post a picture. It will generally look like this but can look different depending on what kind of piping is used. 40 years old it should still have a cleanout.
