Key steps to tackle a sewer gas odor:

---

Identify the source:

• Check all drains, especially those with infrequently used appliances, to see if the P-trap (the curved section under the drain) contains water.
• If the P-trap is dry, pour water down the drain to refill it.
• Look for signs of leaks or damage around plumbing fixtures.

Clean and deodorize:

• Pour a cup of baking soda down the drain, followed by a cup of vinegar.
• Let the mixture sit for a few minutes, then flush with hot water.
• Repeat this process for all drains in your home, including floor drains.

Improve ventilation:

• Open windows and doors to air out the affected area.
• Run exhaust fans in the affected area to circulate air.

Consider commercial drain cleaners:

• If the odor persists, use a commercial drain cleaner specifically designed to break down organic matter in drains.
• Always follow the manufacturer's instructions carefully.

When to call a plumber:

---

Severe odor:

• If the sewer gas is strong and widespread, even after basic cleaning attempts, contact a plumber immediately.

Visible damage:

• If you see signs of cracked pipes, leaks, or damaged plumbing fixtures, call a plumber for repairs.

Recurring issues:

• If the odor keeps coming back after cleaning, a professional inspection is likely necessary to identify the root cause.
