Sewer BackWater Valve Installation

In certain situations, flooding can cause wastewater from sewer lines to backup into houses through drain pipes. This not only can cause damage that is difficult and costly to repair, but also presents some serious health concerns for you and your family. The best way to protect against sewage backups is to install sewer backwater valves, which are designed to block backflow of sewage into the home.


At DrainCity Plumbing Company, all our technicians are licensed and qualified to provide this service. We will install the backwater valves, prepare the permit for installation, and provide you with all information for a sewer backwater valve installation subsidy, that you as the homeowner can take advantage of. With the Basement Flooding Protection Subsidy Program in Toronto and other municipalities, owners of residential homes can receive a large subsidy on every property taking flood protection measures, such as installing or replacing back-water valves, sump pumps, and other equipment to prevent water damage.
