Work through your situation

- IfSeveral drains are slow but nothing has backed upThenLimit water use and schedule a visit soon. Ask for a camera inspection.
- IfOne sink or shower is slowThenUsually safe to wait for a scheduled visit or try simple steps like cleaning the strainer.
- IfAn odor near the cleanout or floor drains with no backupThenSchedule a check. Look for a missing cleanout cap or dry floor drain trap first.

Common questions
Is a slow drain an emergency?
Usually not on its own. It becomes urgent when several drains are involved, sewage appears or the outdoor cleanout overflows.
Can I keep using one bathroom if another is backing up?
If the backup is from the main line, any water you use can surface at the lowest drain. Stop all water use until the cause is known.
What if I smell gas, not sewer odor?
Leave the building and call 911 or SoCalGas from outside. Do not use switches or flames.
