Quick checklist
- Pour water into the sump basin until the float rises and the pump turns on.
- Confirm the pump empties the basin and shuts off cleanly without rattling, grinding, or humming.
- Check that the float is not visibly blocked by the basin wall, cord, lid, or debris.
- Check that the discharge outlet is open, draining away from the foundation, and not buried by leaves, snow, ice, or landscaping.
- Listen for water rushing back into the pit after shutoff, which may point to a check valve issue.
- Test the alarm or backup system if one is installed and review battery age or warning lights.
- Request quotes before the storm season if the pump is old, running constantly, protecting finished space, or missing backup protection.
How often should you run this checklist?
Run it before spring thaw, before forecasted heavy rain, before leaving town during storm season, and before finishing or remodeling a basement.
What problems should trigger a quote request?
Request quotes if the pump does not start, runs but does not move water, short-cycles, sounds strained, lacks backup protection, or has an unclear discharge path.
What does this checklist not replace?
It does not replace a professional inspection, electrical safety review, or emergency service when water is actively entering the basement.
