A sewer backup can cause hundreds of dollars in damage to your home. But thankfully there is a solution that can ensure you never have to face a sewage problem and the solution is a backwater valve. It allows one way flow from your house to the sewer. Backwater valves are designed for indoor and outdoor use. This is a device that prevents sewage from flowing back into the building. Backwater valve comes in both manual and automatic versions. Backwater Valves in Toronto are required to protect drainage openings that are installed in a basement. It allows the waste water to drain out of the system. Call us anytime at 416-824-3352 to get a Quote on our services.
