Hayward CL200EF in-Line Automatic Chlorine Feeder, Offline Pool Chlorinator and Chlorine Dispenser, Up to 9 lb Capacity, for In-Ground Swimming Pools

The Hayward CL200EF in-Line Automatic Chlorine Feeder stands out as the premier choice for in-ground pool owners seeking consistent sanitation. With a robust nine-pound capacity, this unit simplifies chemical management by automating the dispensing process, ensuring your pool remains clear and balanced throughout the busy swimming season.

Integrating a chlorinator system price into your annual maintenance budget is a smart move for long-term pool health. The Hayward CL200EF is engineered for in-line installation, meaning it becomes a permanent fixture in your plumbing configuration. This design choice generally leads to a more streamlined and efficient flow of water through the chemical chamber, allowing for precise control over chlorine levels. While the unit is highly regarded for its durability, potential buyers should verify that their existing plumbing diameter is compatible with the intake and output ports before purchasing. Proper installation is critical to prevent leaks and ensure the feeder operates exactly as intended for your specific pool size.

Practical fit

Because this is an in-line model, it requires cutting into your existing return piping. This setup is ideal for those who want a permanent, clean look and a stable chemical output. Before committing to this model, measure your current pipe diameter and ensure you have sufficient clearance in your equipment pad area. If your plumbing layout is tight or difficult to access, you may need to consult with a professional to ensure the installation is secure. A well-fitted in-line system provides a reliable, set-it-and-forget-it solution that minimizes the time you spend manually adding chemicals to your pool water.

Tradeoffs and ownership

Ownership of an in-line chlorinator requires regular attention to the chemical tablets used. You must monitor the feeder capacity to ensure it does not run empty, which would lead to a drop in sanitation levels. The primary tradeoff is the permanency of the installation; once the pipes are cut, you are committed to this style of feeder. Users should also regularly inspect the O-rings and seals for wear to prevent leaks. While the chlorinator system price is a factor, consider the long-term value of reduced manual labor and the consistent water quality provided by this reliable Hayward unit.

What to look for

Assessing Your Pool Plumbing

Before selecting a chlorinator, determine whether your pool plumbing requires an in-line or off-line model. In-line units are installed directly into the return line, while off-line units use flexible tubing to bypass the main plumbing. Consider the available space near your pump and filter system. Always measure your existing pipe diameter to ensure the unit you choose is compatible with your current setup, preventing installation complications.

Evaluating Total Capacity Needs

Consider the size of your pool and the volume of chlorine required to maintain proper sanitation. Most standard feeders hold up to nine pounds of tablets. If you have a larger pool, you might need to refill the feeder more frequently. Evaluate your tolerance for maintenance tasks versus the convenience of a larger capacity unit. Choose a size that aligns with your pool's specific chemical demand.

FAQ

Pool Maintenance — FAQ

How do I determine if I need an in-line or off-line chlorinator?

The choice depends on your existing plumbing configuration. In-line chlorinators are installed directly into the return pipe after the filter and heater. Off-line chlorinators use flexible tubing to pull water from before the filter and return it after the heater. Check your plumbing layout to see which setup is feasible. If you have limited space in your return line, an off-line model is often the better choice. Always ensure your plumbing can accommodate the unit before purchasing.

Can I use any type of chlorine tablet in these feeders?

Always refer to the manufacturer's manual for your specific chlorinator model. Most feeders are designed for use with slow-dissolving trichlor or bromine tablets. Never mix different types of chemicals, as this can cause dangerous reactions. Using the wrong type of tablet can also damage the feeder or affect your water chemistry. Stick to the recommended tablet size and type to ensure safe and effective operation of your pool's sanitation system.

How often should I check the chlorine levels in my pool?

You should test your pool water at least twice a week using a reliable test kit. Factors like sunlight, pool usage, and temperature can significantly affect chlorine consumption. Adjust the dial on your chlorinator to increase or decrease the chlorine output based on your test results. Consistent monitoring is the best way to maintain safe and clear water. If you notice large fluctuations, verify that your feeder is operating correctly and that the tablets are dissolving properly.

Is it safe to install a chlorinator myself?

If you are comfortable with basic plumbing and have the necessary tools, you may be able to install a chlorinator yourself. However, if you are unsure about the process, it is highly recommended to hire a qualified pool professional. Improper installation can lead to leaks, pressure issues, or damage to your filtration system. Always follow the manufacturer's installation instructions carefully and adhere to any local building codes or safety guidelines regarding pool equipment modifications.

What is the typical lifespan of an automatic pool chlorinator?

The lifespan of a chlorinator depends on the quality of the unit, how well it is maintained, and the chemical environment of your pool. With proper care, including regular cleaning and replacing worn seals, a high-quality unit can last for several years. Exposure to harsh chemicals and environmental conditions will eventually cause the plastic to degrade.

Why is the chlorinator system price so varied across different models?

Price variation is typically due to differences in material quality, capacity, brand reputation, and additional features. Premium models may use more durable, UV-resistant plastics and offer more precise flow control, which can justify a higher price. Budget models are often simpler in design and may use more basic materials. When evaluating the price, consider the long-term costs of maintenance and the likelihood of needing to replace the unit sooner compared to more robust, higher-priced alternatives.

What should I do if my chlorinator is leaking?

First, turn off your pool pump and close the control valve to stop the flow of water. Inspect the unit to locate the source of the leak, which is often a worn O-ring, a loose connection, or a cracked housing. If it is a simple seal issue, replacing the O-ring may solve the problem. If the housing itself is cracked, the unit will likely need to be replaced. Never attempt to patch cracks with tape or glue, as this is not a permanent or safe fix.

How do I winterize my chlorinator system?

To winterize, turn off the pump and remove all remaining chlorine tablets from the feeder. Drain the water from the unit using the drain plug. Some owners choose to remove the entire feeder and store it in a dry, protected place for the winter. If you leave it installed, ensure it is completely dry and leave the lid loose to prevent moisture buildup. Following these steps helps prevent damage from freezing temperatures and ensures the unit is ready for the next season.

Final verdict

Bottom Line

Choosing the right chlorinator requires balancing your pool's plumbing layout with your long-term maintenance goals. Models like the Hayward CL200EF offer reliable, in-line performance for standard setups, while off-line options provide flexibility for unique configurations. By focusing on build quality and compatibility, you ensure a consistent sanitation routine that protects your pool water while minimizing the frequent manual labor associated with traditional chemical dosing methods.
