About This Product
Protect basements and other low-lying areas from sewer backflow with the ABS 4 in. Backwater Valve. Designed for horizontal installation, this lightweight and chemically resistant valve provides a reliable one-way flow system. The quick-action flapper opens to allow waste to pass through and automatically closes to prevent reverse flow. Featuring an elastomeric gasket for a watertight seal, the flapper is also removable and replaceable if needed. The valve’s neoprene-gasketed access cap offers secure sealing, and hub outlets fit 4 in. DWV pipe. Ideal for use in residential or commercial waste systems, this valve offers a durable and cost-effective solution.
