Key takeaways
- Dry traps cause sewer odors
- Floor drains often back up in heavy rain
- A backwater valve can reduce backups
- Keep rarely used drains filled with water
Why floor drains smell
A floor drain has a trap that holds water to block sewer gas. If it dries out, odors rise. Pouring water in every few weeks, or using a trap primer, fixes it.
Why they back up
A blocked or overloaded main sends water up the lowest opening, usually a basement floor drain. Roots, grease and heavy rain are common triggers.
Backwater valves
A backwater valve closes if sewage flows backward and can protect a basement. It needs periodic maintenance.
Cleaning floor drains
Remove the grate, clear debris and flush. A camera shows what the line behind the drain looks like.
When to call
If a floor drain gurgles, backs up or smells even when wet, schedule a visit before the next storm.
Quick answers
Can I pour bleach in a floor drain?
Water is best. Harsh chemicals are not needed and can damage plumbing.
Does every basement need a backwater valve?
Not every one. It depends on the home and the system.
