Sandpiper AODD Pump Flap Valves
Browse genuine Sandpiper AODD pump flap valves for compatible Heavy Duty Flap Valve and BEAST pump models. A flap valve is the moving wet-end check-valve component that opens away from and closes against its mating seat as the pump cycles.
The correct replacement depends on the pump model, pump size, pump construction, flap valve material and manufacturer part number. Pumps of a similar size should not be assumed to use the same flap valve.
Sandpiper service manuals may describe this component as Flap Valve, Valve, Flap or Valve, Flap Assembly depending on the pump model. This store groups these replacement components under Flap Valves for easier product selection.
Select your Sandpiper pump type below to find compatible flap valve materials and manufacturer part numbers.

What Is a Sandpiper AODD Pump Flap Valve?
A Sandpiper flap valve is the moving component within the pump's wet-end flap check-valve arrangement.
As the pump cycles, the flap opens away from its mating seat to permit forward fluid movement and returns towards the seat to restrict reverse flow.
The flap valve is not the complete check-valve system. Flap valve seats, hinge components, retainers, wear components and seals may be separate replacement parts depending on the Sandpiper pump model.
How to Select the Correct Sandpiper Flap Valve
Important: Do not select a flap valve by pump size alone. Similar-sized Sandpiper pumps can use different flap valve materials or manufacturer part numbers.
Sandpiper Flap Valve Material & Compatibility
Flap valve materials vary according to the Sandpiper pump model and construction. Not every material is available for every Heavy Duty Flap Valve or BEAST pump configuration.
Material availability is model-specific. Always verify the exact flap valve material and manufacturer part number against the applicable Sandpiper service manual.
Selection Note: Metallic or Non-Metallic describes the compatible pump construction and does not automatically identify the flap valve material.
