Waterway 600-7030 TrueSeal Straight Check Valve (1-1/2" Socket x 2" Spigot, CPVC)
The Waterway 600-7030 is a TrueSeal straight-body check valve designed to prevent backflow in pool and spa plumbing. It features a 1-1/2" slip (socket) connection on one end and a 2" spigot connection on the other, making it a common choice for equipment pads and spa plumbing where mixed pipe sizes are used. The service-friendly design uses a union lock ring for quick internal access and a low-resistance flapper to help maintain good flow.
Key Specifications
- Manufacturer: Waterway
- Part Number: 600-7030
- Type: TrueSeal check valve (straight body)
- Body Material: CPVC (chemical- and heat-resistant for demanding pool/spa applications)
- Connections: 1-1/2" socket (slip) x 2" spigot
- Access: Union lock ring for easy service (no screw holes to strip)
- Internal Sealing: Thermoplastic flapper with stainless steel spring and corrosion-resistant pivot/pin
- Flow: Reversible flow design (install in the direction you need by orienting the valve correctly)
Common Uses
- Heater protection: Helps prevent reverse flow through heaters and heat exchangers (when plumbed per system design).
- Chlorinator/salt system protection: Helps reduce chemical backflow into equipment when the pump shuts off.
- Spa/pool combos: Helps keep water from draining back and supports more consistent mode switching.
- Water features: Helps reduce line drain-down and backflow where check valves are specified.
Why Replace a Check Valve?
- Sticking flapper or weak spring causing backflow or drain-down
- Chattering noise, vibration, or intermittent sealing
- Cracks, warping, or leaks at the body or union ring
- System performance issues caused by reverse flow after shutdown
Installation Notes
- Dry-fit first to confirm orientation and clearance for future service access.
- Install in the correct flow direction (follow the molded flow indicator on the valve body if present).
- Use the proper primer/cement for CPVC/PVC plumbing and allow full cure time before pressurizing.
- Support the plumbing so the valve body is not under stress; misalignment can cause leaks over time.
- Whenever possible, place the valve where it can be accessed for inspection and cleaning.

Maintenance Tip
If you notice water draining back or chemicals migrating when the pump shuts off, inspect the check valve for debris on the flapper sealing surface. Many sealing issues are caused by small grit or scale buildup—cleaning the internals can restore proper operation without replacing the entire valve. Always confirm the valve is accessible before cementing it into place.
