Wastewater treatment systems use biological processes to treat waste, so you shouldn’t put anything into them that hasn’t first been ingested. Toilet paper, mild detergents and water from washing are exceptions.

The following can cause your septic tank to be blocked or upset the biology of your septic system:

  • Chemical drain cleaners, oven cleaners, and other products containing lye
  • Backwash brine from water softeners
  • Unused medicines and pharmaceuticals
  • Excessive amounts of household cleaners, including chlorine bleach
