Does Frigidaire clothes washer drain hose have a check valve?

Frigidaire clothes washers typically do not come with a built-in check valve in the drain hose. The drain hose is designed to facilitate the smooth flow of wastewater from the washer to the household drain or plumbing system. While some washers may have a backflow prevention feature, such as an air gap or a check valve, it is not a standard feature in Frigidaire washers.
If you require backflow prevention for your specific installation, you may need to consult with a plumber or consider adding an external check valve or backflow prevention device to the plumbing system. It is recommended to follow the manufacturer's instructions and guidelines for proper installation and maintenance of the drain hose to ensure optimal performance of your Frigidaire washer.
