Restore Safe, Reliable Chlorine Production in Hayward-Style Salt Systems

A salt chlorine generator can only operate safely when proper water flow is present. The Swimables SW-76-110 Hayward® Style Salt System Flow Switch is a critical safety and control component designed to verify circulation before chlorine generation begins. When installed in compatible Hayward-style salt systems, this flow switch ensures the cell only produces chlorine when water is moving correctly through the plumbing.

If a flow switch fails, salt systems may display flow-related error codes, shut down chlorine production, or—more dangerously—attempt to operate without adequate circulation. Replacing a faulty flow switch restores proper system logic, protects expensive salt cells, and ensures safe operation of the entire sanitation system.

This is a pool-specific electronic flow sensor, not a standard plumbing valve or mechanical switch.

What a Salt System Flow Switch Does

The flow switch monitors water movement through the return line feeding the salt cell. When sufficient flow is detected, the switch signals the control board that conditions are safe for chlorine generation.

A properly functioning flow switch:

• Confirms adequate water circulation

• Prevents chlorine generation during low-flow conditions

• Protects the salt cell from overheating

• Prevents gas buildup inside the plumbing

• Enables normal salt system operation

If the flow switch is not working correctly, the salt system may refuse to generate chlorine—or operate unsafely.

Flow switch service is commonly performed alongside components in the Salt Chlorine Generator Collection.

Hayward® Style Compatibility

The Swimables SW-76-110 is engineered as a Hayward-style replacement flow switch, designed to match the form, function, and electrical behavior of compatible Hayward salt system sensors.

Compatibility highlights include:

• Hayward-style salt chlorine generators

• Proper thread and probe length

• Correct wire configuration

• Designed for inline installation near the salt cell

This component is intended for style compatibility, meaning it mirrors the physical and operational characteristics used across many Hayward salt systems.

Common Signs a Flow Switch Needs Replacement

Flow switches are exposed to constant water flow, debris, and electrical cycling. Over time, sensors can stick, corrode, or fail electronically. Replace the flow switch if you notice:

• “No Flow” or “Check Flow” error messages

• Salt system not producing chlorine despite good chemistry

• Intermittent system shutdowns

• Visible scale or debris buildup on the sensor

• System generating chlorine only sporadically

Many salt system issues are incorrectly blamed on the cell itself when the real problem is a faulty flow switch.

If chlorine output issues persist, related equipment in the Saltwater Pool Systems Collection should also be inspected.

Why Proper Flow Detection Is Critical

Salt systems generate chlorine gas inside the cell housing. Without sufficient water flow, this gas cannot dissipate safely and may damage equipment or plumbing.

A working flow switch:

• Prevents chlorine generation during pump failure

• Protects plumbing from gas accumulation

• Ensures correct chlorine dispersion

• Extends salt cell lifespan

• Maintains safe system operation

For this reason, flow switches are considered a mandatory safety component, not an optional accessory.

Built for Saltwater Pool Environments

The Swimables SW-76-110 flow switch is manufactured specifically for saltwater pool conditions.

Design considerations include:

• Resistance to salt and chlorinated water

• Durable sensor housing

• Reliable electrical signaling

• Compatibility with standard control boards

This ensures consistent operation even in harsh chemical environments.

Installation Considerations

Replacing a salt system flow switch is typically straightforward but must be done correctly to ensure accurate flow detection.

General Installation Overview:

1. Turn off power to the pool pump and salt system

2. Relieve pressure from the plumbing

3. Remove the old flow switch from the return line

4. Install the new SW-76-110 in the correct orientation

5. Reconnect wiring to the control board

6. Restore power and verify proper operation

Orientation is critical—installing the switch backward can prevent proper operation.

Professional installation is recommended if you are unfamiliar with salt system wiring or plumbing.

Ideal Applications

The Swimables SW-76-110 Hayward-style flow switch is ideal for:

• Hayward-style salt chlorine generators

• Residential in-ground pools

• Salt systems displaying flow-related errors

• Preventative maintenance during salt cell service

• Replacing corroded or unreliable sensors

This part is commonly replaced during seasonal service or when upgrading older salt systems.

Supports Overall System Performance

A reliable flow switch ensures the salt system operates only under safe hydraulic conditions. This helps protect:

• Salt chlorine generator cells

• Plumbing and return lines

• Pool pumps

• Water quality consistency

Stable flow detection supports balanced sanitation and reduces unnecessary service calls. For circulation optimization, this component works alongside equipment from the Pool Pumps Collection.
