Flow Switch for Hayward (Replacement Kit)
The EXCELFU flow switch provides compatible replacement for Hayward GLX-FLO-RP and related Goldline/Aqua Rite systems. It supports multiple model families, including Aqua Rite, AquaPlus, Aqua Logic, and more. The unit includes a 15-foot cable and gasket/sealant tape for secure, leak-free installation. Its main purpose is to monitor water flow and prevent damage to the salt cell and chlorine generator by stopping operation if flow is insufficient.
- Replacement compatibility: GLX-FLO-RP, GLXFLORP, OPT-F/S, GLX-FLO-HP
- Designed for Goldline and Aquarite salt systems
- 15-foot cable with gasket and sealant tape
Hunter PGV 1″ Electric Sprinkler Valve
The Hunter PGV valve combines inline irrigation valve control with built-in flow considerations. It uses a standard 1″ NPT female thread to fit common PVC piping and a 24V AC solenoid for easy integration with standard irrigation timers. While not a traditional flow switch, this valve helps regulate flow to individual zones, supporting system efficiency, reduced misting, and healthier landscapes.
- 1″ NPT female threading for easy compatibility
- Pre-installed 24V AC solenoid
- Inline irrigation valve designed for precision control
Flow Switch for Hayward (15 Foot Cable)
The GZKEFEIS flow switch serves as a robust replacement for Hayward Goldline Aquarite salt systems. It monitors water flow to prevent NO FLOW errors and protects the salt cell and chlorine generator. The kit includes a 15-foot cable, 1/2-inch threads, a gasket, and sealing tape to ensure a leak-free installation, making DIY setup straightforward for pool professionals and homeowners alike.
- Compatible with GLX-FLO-RP, GLX-FLO-HP, Aqua Rite, and Pro Logic
- 15-foot cable with standard 1/2 inch threads
- Leak-proof sealant and gasket included
GLX-FLO-RP Flow Switch (Pool System)
This FBULWSEC flow switch is designed as a direct replacement for Hayward Goldline Aquarite flow control components. It integrates with AquaRite, AquaLogic, and related systems to automatically shut down the chlorine generator when flow is insufficient, protecting the salt cell. Installation is simplified by standard 1/2″ threads and a 15-foot cable with a plug-and-play phone jack connector. Sealant tape aids in a tight, leak-free seal.
- Direct replacement for GLX-FLO-RP family
- Protects salt cells and chlorine generators
- Plug-and-play 15-foot cable with 1/2″ threads
ONLYWON Flow Switch And Sensor
ERSIQI’s ONLYWON flow switch offers high-sensitivity water flow monitoring suitable for diverse applications such as water heaters, solar systems, and pumps. The device converts a specific flow rate into a switch-type signal, enabling automatic control of pumps and solenoid valves. It features a G1/2 inlet/outlet and supports installation at various angles, with an emphasis on ease of wiring and monitoring via LED indicators.
- G1/2 thread and versatile installation angles
- High-sensitivity flow detection for automatic control
- LED indicators for quick status checks
Buying Guide
Key considerations when choosing a flow switch for sprinkler and pool systems include compatibility, thread size, and cable length. Ensure the unit supports your specific brand (e.g., Hayward Goldline/Aquarite) to prevent NO FLOW errors that can damage salt cells or chlorine generators. A longer cable (like 15 feet) simplifies installation away from the pump or control box, while standard 1/2-inch threads provide broad compatibility with common plumbing. Look for included gaskets and sealant tapes to reduce leaks. For pool systems, verify that the switch communicates correctly with your salt cell or chlorinator to protect your equipment during low-flow events. Finally, consider whether a flow switch is the sole protection device or if it should be paired with a backflow preventer and anti-siphon valve for a complete, safe irrigation or pool setup.
Different perspectives worth weighing:
- Pool-focused users may prioritize compatibility with AquaRite and Pro Logic series, and prefer 15-foot cables for easy reach.
- Irrigation-only setups should emphasize robust 24V-compatible valves or switches that integrate with standard timers and controllers.
- DIY homeowners benefit from clearly labeled installation steps, gasket kits, and included sealant for a leak-free seal.
- Commercial installations may require longer cable runs, modular wiring, and redundancy in flow monitoring.
