Jandy 7307 Large Check Valve – 2½″ x 3″ (Pro Series)
Part # 7307 — a heavy-duty large check valve by Jandy designed for high-flow pool and spa systems. Features a swing/spring check mechanism and a clear lid for quick inspection. Configured for 2½″ slip inlet and 3″ slip outlet plumbing, built in CPVC material for durability in pool environments.
Key Features
- Large 2½″ × 3″ plumbing size accommodates high flow rates up to approx. 170 GPM.
- 180° orientation model (also available in straight configuration) for flexible plumbing layouts.
- CPVC construction resists pool chemical exposure and long-term UV, sunlight or freeze conditions.
- Clear removable lid for visual inspection of the internal flapper and seal; easy to service without plumbing removal.
- Low head-loss design and swing/spring check action helps prevent reverse flow on start/stop cycles and protects equipment.
Typical Applications
Ideal for large residential or light-commercial pool systems where plumbing sizes are 2½″ inlets and 3″ outlets, such as when using large pumps, multiple return lines, water features or high-flow filtration systems. Often used between pump discharge and filter or as protective check valve on suction side applications.
Installation & Compatibility Notes
Shut off the pump and relieve pressure before servicing. Select the correct orientation (180° or straight) to match your plumbing layout. Use solvent-cement or compatible union/adaptor to connect the 2½″ inlet and 3″ outlet. After installation, verify the check valve lid seals properly, runs free without debris, and no reverse flow occurs when the pump stops.
Why Choose This Valve?
The Jandy 7307 is a premium, professional-grade check valve sized for demanding pool systems. Its large size, durable CPVC construction, and service-friendly design make it a smart choice for pool pros and serious homeowners who want reliable flow control and equipment protection.
Maintenance Tips
- Periodically inspect the lid and internal flapper for debris, wear or corrosion. Remove lid and clean if needed.
- Check for any flow reduction or noise at valve; elevated back pressure may indicate internal wear or blockage.
- Ensure unions or solvent-cement joints remain leak-free and check valve is not leaking under normal operation.
- During off-season or winterizing, consider removing debris and ensure check valve lid is tight and sealed to prevent water intrusion or freeze damage.
