Product Description
The NDS 1400-15 is a PVC compression swing check valve designed for sump pump discharge lines. It accepts both 1-1/4 inch and 1-1/2 inch pipe connections using a compression-style fitting, eliminating the need for solvent cement on the joint. The swing check mechanism allows flow in one direction and closes automatically when flow stops or reverses, preventing backflow from re-entering the sump basin. This valve is installed by plumbers and sump pump service technicians as part of a complete discharge assembly.
This valve is suited for residential sump pump applications where a reliable, easy-to-install check valve is required on the discharge riser. The dual-size compression design accommodates the two most common sump pump discharge pipe sizes, making it a practical fit for new installations and retrofit work alike. It is appropriate for interior drainage systems where backflow prevention on the pump outlet is required by local plumbing codes.

Installation Notes
Installation is typically performed by a licensed plumber or qualified sump pump technician. Disconnect power to the sump pump before beginning any work on the discharge line. Ensure the valve is oriented correctly with the flow arrow pointing away from the pump to allow proper check valve operation. Verify local plumbing code requirements for check valve placement and pipe support on the discharge riser.
