Case Study: Backwater Valve Installation to Prevent Basement Sewer Backups in Brampton

Location: Brampton, Ontario
Client: The Khan Family
Issue: Sewer backup during summer storm causing basement flooding
Service: Backwater valve installation with plumbing modification and city rebate support

The Challenge

The Khan family lives in a mid-century home in Brampton’s Peel Village area. During a severe summer storm, the municipal sewer system became overwhelmed, resulting in wastewater backing up into their basement through the floor drain and laundry sink. The flooding caused property damage and health concerns due to contaminated water exposure.

Determined to prevent this from happening again, the Khans contacted Direct Waterproofing for a solution that would protect their home from future sewer system overloads.

Our Solution

We recommended installing a backwater valve—a one-way device that prevents wastewater from flowing back into the home during a city sewer backup. This installation was eligible for the City of Brampton’s Basement Flooding Protection Subsidy, which partially reimburses homeowners for the cost.

Installation Process:

• Permit & Inspection Coordination: Handled all necessary permits with the City of Brampton and scheduled the required post-installation inspection.
• Drain Line Access: Excavated a small section of the basement floor to access the main sewer line.
• Backwater Valve Installation: Cut and modified the plumbing to install a code-compliant backwater valve with an accessible inspection port.
• Testing: Ran system tests to ensure proper closure and water flow direction.
• Cleanup & Subsidy Support: Restored the concrete floor and assisted the homeowners with completing the city rebate application process.
  

The Result

The new backwater valve now protects the Khan family’s home from potential sewer backups. Since installation, they have had no further flooding incidents, and they received a rebate from the city to offset part of the project cost.

Client Testimonial

“We wish we had installed the valve sooner. Direct Waterproofing took care of everything—from permits to clean-up—and even helped us file for the rebate. Our basement is safe, and our peace of mind is restored.”
