If you want to compare an OEM-style Hayward option, review the Hayward GLX-FLO-RP 15 cable flow switch assembly without tee before choosing the replacement.
Compatibility Notes
This Optimum Pool Technologies flow switch is intended for compatible Hayward salt chlorine generator systems. It should not be treated as a universal flow switch for every chlorinator, control box, or pool plumbing setup.
For another standard Hayward flow switch option, the Hayward GLX-FLO 15 feet cable flow switch may be useful to compare with your current part.
If your system uses an Aqua Trol HP-style setup, the Hayward GLX-FLO-HP flow switch assembly may be a better match than this standard flow switch style.
When to Replace the Flow Switch
A flow switch may need replacement if your salt chlorine generator shows “No Flow,” “Low Flow,” or a similar warning while the pump is running and circulation is normal. It may also need replacement if the cable is damaged, the paddle is stuck, or the connector no longer reads properly.
Before replacing the switch, check the pump basket, filter, valves, salt cell, water level, and plumbing for restrictions. Poor circulation can trigger the same warning even when the flow switch is still working.
Installation Guidance
Turn off power to the pump and salt chlorine generator before removing or installing the flow switch. Release system pressure and confirm the correct flow direction before installation.
Install the switch into the existing tee in the proper orientation so the paddle sits correctly in the water stream. Route the cable away from sharp edges, hot surfaces, moving equipment, and areas where it can be pinched.
After installation, restart the pump, check for leaks, and confirm that the chlorinator recognizes proper flow.
Tee and Related Parts
Because this kit does not include the tee, inspect your existing tee before ordering. If the tee is cracked, stripped, leaking, or missing, the Hayward GLX-FLO-T flow switch tee replacement may need to be reviewed separately.
If you need a complete flow switch kit with a tee included, compare this item with the flow switch assembly with PVC pipe tee before choosing the replacement.
Maintenance and Troubleshooting
Inspect the flow switch during seasonal startup and whenever the chlorinator shows flow-related alerts. Keep the pool filter clean, maintain proper water level, and check the salt cell for scale buildup or debris.
For complete system reference, the Hayward W3AQR15 AquaRite salt chlorination system can help buyers understand the type of Hayward setup that commonly uses flow switch monitoring.
If a new flow switch does not clear the warning, check water pressure, valve position, connector fit, control board condition, and overall pool circulation before replacing more parts.
