Backwater Valve vs Sump Pump vs Foundation Drain Work
| Measure | Best for | Rebate watchout |
|---|---|---|
| Sanitary backwater valve | Reducing risk of sewage backup through the sanitary lateral. | Many rebate paths require a municipal permit and inspection. Shared laterals, basement apartments, or the wrong lateral can affect eligibility. |
| Storm backwater valve | Reducing risk of storm sewer backup where the home has a storm lateral connection. | Do not assume a sanitary valve and storm valve qualify under the same program. |
| Sump pump and pit | Collecting foundation drain water and pumping it away from the home. | Discharge location, downspout disconnection, and new vs replacement equipment rules matter. |
| Foundation drain or weeping tile work | Redirecting water away from the sanitary/storm system or correcting drainage at the foundation. | Some programs cover disconnection/capping but not new waterproofing, crack repair, or interior finishes. |
Permit / Inspection / Licensed Contractor Notes
- Windsor says a plumber licensed with the City must complete the work.

- Confirm who applies for permits and who books the final inspection.
- Get an itemized quote that separates labour, materials, taxes, camera inspection, and each flood-prevention measure.
- Ask whether the contractor will provide sketches, licence numbers, invoices, photos, and inspection documents where the official program requires them.
- Confirm the contractor will not start work until pre-approval is received where pre-approval is required.
- Ask how they determine sanitary vs storm lateral connections before recommending a valve.
- Keep every invoice, permit, inspection result, application email, and paid-in-full receipt.
