Slow Drains and Septic Backups
What to do now
If sewage is backing up indoors, stop using water and call for help. Pause showers, flushing, laundry, and the dishwasher. Keep people and pets away from sewage.
If one sink, tub, or toilet is slow and the others work normally, start with a plumber. If several fixtures slow down or gurgle together, reduce water use and call a septic service provider or plumber who can help determine where the restriction is.
What might be causing it?
One slow fixture can point to a local clog. Several affected fixtures can point to a shared drain or the main line, but a clogged effluent filter, pump problem, or overloaded drain field can also restrict flow. The symptoms alone can’t identify which part needs attention.

What to tell the person you call
- Which fixtures are affected and where sewage appeared first.
- When it started and whether it followed heavy water use or rain.
- Whether there’s an alarm, wet ground, or a recent pump-out or filter cleaning.
