Product Description
The NDS 1205-07 is a 3/4-inch PVC spring check valve with socket ends (TxT) designed to allow one-directional flow and prevent backflow in residential and light commercial plumbing and irrigation systems. The spring-loaded disc closes automatically when forward flow stops, blocking reverse flow without requiring manual intervention. At 0.15 pounds, this lightweight valve is well-suited for installations where added system weight is a concern. Plumbers and irrigation technicians install this valve inline to protect pumps, meters, and other system components from backflow damage.
This valve is typically used in 3/4-inch PVC piping systems for potable water supply, irrigation mainlines, and drainage applications. The socket ends accept standard Schedule 40 PVC pipe with solvent cement, making it compatible with common residential and light commercial piping configurations. It is appropriate for both new construction and retrofit installations where a low-profile, non-return valve is needed.
Key Features
- Spring-loaded disc provides automatic closure on flow reversal
- 3/4-inch TxT (socket by socket) end connections for solvent-cement joining
- PVC construction offers corrosion resistance in wet and chemical environments
- Lightweight at 0.15 pounds for easy inline installation
- Compact design fits standard PVC piping layouts without extensive rework
Compatibility
Designed as an OEM-style drop-in replacement or new-installation check valve for 3/4-inch Schedule 40 PVC piping systems in residential and light commercial plumbing and irrigation applications.
Installation Notes
Installation is performed by licensed plumbers or qualified irrigation technicians. Shut off the water supply and relieve system pressure completely before cutting into an existing line. Use appropriate PVC primer and solvent cement per the pipe manufacturer instructions and local plumbing code requirements. Verify the flow-direction arrow on the valve body is oriented correctly before cementing joints, as reversing the valve will block forward flow.
