Sewer backup protection
A One-Way Gate Between the City Sewer and Your Basement
When the municipal sewer surcharges during a storm, the pressure has to go somewhere. A backwater valve keeps that somewhere from being your floor drain.
Common warning signs
- Water rising from the floor drain during heavy rain
- Gurgling from drains when it storms
- A previous sewer backup in the basement
Common causes
- Municipal sewer surcharge during intense rainfall
- Combined storm and sanitary connections
- Downstream blockages in the city main
- Basement fixtures below street level

- 03
