Hello,
My washer backs-up into my kitchen sink when it drains. What could the problem be, or is it just an old house?
The sink fills about half-way, but never overflows. The sink drains a minute or so later and there is a residue with small black chips of grime and a few minutes of local unpleasent odor. My house was built in '69. I am nervouse because my neighbor told me the pipe exiting his house to the back alley had partially collapsed last year and he had to drill into the cement to fix it. He said the pipe installed by the builders was not meant to last beyond 30 years or so.
Thank You For Your Time,
Nathan
