BACKWATER VALVE INSTALLATION - VAUGHAN, TORONTO & THE GTA

Backwater Valve Installation in Toronto & Vaughan — Protect Your Basement

A backwater valve is your home's best defence against sewer backup flooding. Aviv Plumbing installs them correctly and helps you access the City of Toronto rebate program.

REQUEST SERVICE

INTRO

Sewer backup is one of the most costly and disruptive events a homeowner can face. When heavy rain overwhelms the municipal sewer system, sewage can flow backwards through your floor drains and into your basement. A properly installed backwater valve stops this from happening.

Aviv Plumbing provides professional backwater valve installation for homes across Toronto, Vaughan, and the Greater Toronto Area. Our licensed plumbers install the right valve for your drainage system, ensure it meets Ontario Plumbing Code requirements, and complete the work with minimal disruption.

If you’re in the City of Toronto, you may be eligible for the Basement Flooding Protection Subsidy Program — rebates of up to $3,400 for qualifying installations.

  • You live in an area prone to heavy rainfall or combined sewer overflows
  • You want to qualify for the City of Toronto basement flooding rebate
  • Your insurance company has recommended one
  • You're finishing your basement and want to protect the investment

FAQ

Is there a rebate for backwater valve installation in Toronto?

Yes. The City of Toronto Basement Flooding Protection Subsidy Program offers rebates of up to $3,400 for eligible installations. Requirements include a licensed plumber, a permit, and an approved installation.

Most residential backwater valve installations are completed in one day. The process involves locating the drain line, cutting a section of concrete floor, installing the valve and access panel, and patching the concrete.

Yes. Backwater valves should be inspected and cleaned annually to ensure the flap moves freely and seals properly. We recommend checking it every spring before heavy rain season.

A mainline backwater valve protects against sewer backup through your floor drains. It does not protect against surface water entry through windows or foundation walls. A sump pump addresses that risk separately.
