Checklist

Storm aftermath: a 24-hour septic checklist

What to check before you flush, and the order to do it in.


  • Look for standing water over the drainfield — do not pump the tank if groundwater is high
  • Minimize water use for the first 24 hours after the storm passes
  • Check for sewage odor inside the home or near the tank
  • Do not open tank lids while the area is wet
  • Note any gurgling or slow drains and write down the time
  • If saltwater reached the system, plan a follow-up inspection in 30–60 days
  • Document any damage with photos for insurance
