To eliminate a sewer gas smell in your house quickly, start by opening windows and doors immediately to establish cross-ventilation and clear toxic vapors. Next, pour a large pitcher of water down every single plumbing drain in the home—including infrequently used guest bathrooms, laundry rooms, and basement floor drains—to instantly recharge any dried-out P-traps that have lost their protective water seal. For lingering organic slime odors, pour half a cup of baking soda followed by white vinegar down the affected drain, let it fizz for 20 minutes, and flush with hot water. Verification: Inspect all drain openings and P-traps after treatment to confirm that the sulfur and rotten egg odors have completely vanished.
