Where this valve shines
- Sump pump discharge lines: prevents backflow when the pump shuts off or during power outages, helping keep your basement dry and reducing the risk of re-flooding in damp spaces.

- Quick retrofits: designed to drop into standard 1-1/2" piping without custom adapters, making upgrades or repairs faster and simpler. How it solves common problems
- Backflow prevention: by allowing water to move in only one direction, it stops residual discharge from re-entering the pump line, supporting more efficient pumping cycles.
- Durability in wet environments: ABS construction resists corrosion and mineral buildup that can plague metal valves in humid or wet settings.
- Flexible installation: horizontal or vertical mounting means you can position the valve to fit tight spaces or awkward routing without compromising performance. Practical installation tips
- Mount on the discharge side of your pump, ensuring water flows through the valve in the intended direction.
- Keep connections clean and dry during installation; use appropriate clamps or fittings rated for 1-1/2" piping to ensure a tight seal.
- After installation, run a test by operating the pump and verifying that water moves forward with no backflow when the pump stops. The Superior Pump 1-1/2 in. D ABS Check Valve combines straightforward, one-piece inline design with dependable ABS durability to protect your pump system from backflow. It’s an accessible, durable choice for homeowners managing basements, crawl spaces, and outdoor drainage—delivering reliable performance when it matters most.
