SIGNS OF BLOCKAGES
When your sewer is plugged or your septic tank needs pumping, here’s what will happen:
Water backs up out of your tub drain when you flush your toilet.
When you empty your bathtub, the water stops flowing and bubbles back at you or bubbles into the toilet.
When you empty your kitchen sink, the sink water backs up into the toilet.
When you flush your toilet, sewer water backs up through an outside downspout, patio drain, driveway drain, or the lowest floor drain in your house.
When you run a load of laundry, soapy water comes up into a toilet, shower, or floor drain.
