Clear answers before work begins.
What should I do first when my basement floods?
If there is active sewage or an electrical hazard, keep people away from the affected area. Then document what happened and identify whether water is coming from a drain, sump, wall, floor or exterior opening.
Do I need a sump pump or a backwater valve?
They solve different problems. A sump pump manages groundwater and drainage collection; a backwater valve helps protect against reverse sewer flow. The property should be assessed before choosing equipment.
Can one repair eliminate every flood risk?
No. Basement flooding can have multiple causes, so effective protection may involve more than one measure.
