How can I be sure my backwater valve will work?
Backwater valves operate in extremely challenging surroundings. As waste water passes through the valve, it leaves residual oil, feces, hair, toilet paper, chemicals, and paint–anything you would flush or drain out of your home. In a matter of months, this waste residue will build up in and around the valve door, preventing it from functioning properly. It is inevitable. If the municipal system should back up, the backwater valve may fail, which will result in a sewer backup.
The very best way to ensure your backwater valve will work as it should and when needed, is to participate in a Water Management Inspection System by a company specializing in backwater valve maintenance. By allowing a technician to clean, inspect and test your backwater valve on a bi-annual basis, you can be assured that your home is protected from sewer backups. You can think of a backwater valve as having two parts: the valve unit, and the mandatory maintenance required to keep it functioning.
