Buying guide

What to look for

Assessing Your Plumbing Layout

Before purchasing, identify whether your system requires an in-line or off-line feeder. In-line models like the 320 series are installed directly into the return plumbing, which requires cutting pipe. Off-line models like the 300 series connect via flexible tubing, making them easier to install without major plumbing modifications. Verify your pipe diameter, typically 1.5 or 2 inches, to ensure the feeder fittings match your existing setup. A mismatch here will necessitate additional adapters, which can complicate the installation and increase the risk of leaks at connection points. Always check your available space in the equipment pad area to ensure the chosen model fits comfortably without obstructing access to other essential pool components like pumps or heaters.

Chemical Type Compatibility

Confirm that your chosen feeder is explicitly rated for the type of sanitizer you intend to use. While many Rainbow feeders are designed for both chlorine and bromine, the internal components must be chemically compatible with your specific choice. Bromine is often more corrosive than chlorine, so verify that the feeder materials are rated for the intended chemical concentration. Never use a feeder for a chemical type it was not designed for, as this can lead to premature failure of the housing or seals. Always consult the product manual or manufacturer specifications to ensure the unit can safely handle the specific chemical tablets you plan to use for your pool sanitation.

Evaluating Flow Rate Requirements

The feeder must be capable of handling the flow rate of your pool pump system. If the feeder is too small for a high-flow pump, it may create excessive backpressure, potentially damaging the feeder housing or affecting pump performance. Conversely, a feeder that is too large might not provide enough chemical erosion to maintain proper sanitation levels in a small pool. Research the recommended flow rates for each model and compare them against your pump specifications. If your pool has a variable speed pump, ensure the feeder can operate effectively across the different flow settings you use, as lower speeds may result in reduced chemical output during standard operation.

Material and Build Quality

Look for high-quality, chemical-resistant plastics that are designed to withstand the harsh environment of a pool equipment pad. UV resistance is also a critical factor if the feeder will be exposed to direct sunlight. Premium models often feature reinforced housings and more durable seals, which can justify a higher initial investment by reducing the frequency of repairs and replacements. Read through the product descriptions to identify materials that are specifically noted for their durability and long-term performance. Avoid budget models that use thin-walled plastics if you live in an area with high pressure or extreme temperature fluctuations, as these factors can accelerate the aging and cracking of the feeder housing.

Installation and Mounting Needs

Consider the ease of installation for your specific skill level. If you are not comfortable cutting and gluing PVC pipe, an off-line feeder that uses flexible tubing might be the better choice. Check if the product includes all necessary hardware, such as bushings, tubing, and mounting brackets. Some models may require additional parts to complete the installation, so factor these into your total cost. If you are hiring a professional to install the feeder, ask them about their preferred brands and models, as they may have specific experience with the reliability and ease of service for different units, which can save you time and money on future maintenance.

Future Serviceability and Parts

Choose a feeder from a well-established brand where replacement parts are readily available. A feeder is only as good as its ability to be repaired. Check if the manufacturer offers a comprehensive catalog of replacement O-rings, lids, and valves. Being able to easily source these parts will significantly extend the life of your feeder and save you from needing to replace the entire unit when a small component fails. Avoid obscure brands that do not provide clear support or parts diagrams, as you may find yourself unable to perform basic repairs when they are needed most. A reliable, well-supported product is always a safer long-term investment for your pool maintenance.

Verifying Warranty and Support

Check the warranty terms provided by the manufacturer. A solid warranty can provide peace of mind, especially when purchasing a component that will be under constant pressure and exposed to chemicals. Understand what is covered and what is considered normal wear and tear. Keep your proof of purchase in a safe place, as you will need it for any potential warranty claims. Additionally, look for brands that offer clear customer support channels, such as online manuals, troubleshooting guides, or direct help lines. Having access to professional assistance can be invaluable if you encounter issues during installation or if the unit does not perform as expected after you have set it up.

Setup, use, and maintenance

Routine Inspection Protocols

Regularly inspect the feeder housing for signs of cracks, leaks, or degradation caused by harsh sanitizers. Check the O-rings and seals at the lid and union connections to ensure they remain pliable and free of debris. If you notice any water dripping from the feeder unit, immediately turn off the pump and isolate the feeder using the control valves. Examine the internal tubing for signs of mineral buildup or chemical erosion, which can restrict flow and reduce the efficiency of your sanitation system. Always refer to the manufacturer provided manual for specific part replacement intervals, as failing to address worn components can lead to leaks that may damage surrounding pool equipment or pool decking surfaces over time.

Chemical Loading Best Practices

When adding chlorine or bromine tablets, always turn off the pump and allow the pressure to dissipate before opening the lid. Wear appropriate protective gear, including gloves and eye protection, to avoid direct contact with concentrated chemicals. Never mix different types of chemicals within the feeder, as this can cause dangerous reactions. Ensure the tablets are placed securely in the chamber according to the manufacturer instructions. After loading, replace the lid carefully, ensuring the O-ring is seated correctly to create a proper seal. Tighten the lid by hand only, as over-tightening with tools can crack the plastic housing or damage the threads, leading to persistent leaks that are difficult to seal later.

Seasonal Winterization Steps

Before closing your pool for the season, the feeder must be drained completely to prevent water from freezing and cracking the plastic housing. Remove all remaining chemical tablets from the chamber and dispose of them according to local hazardous waste regulations. Rinse the interior thoroughly with fresh water to remove any chemical residue. If the feeder is an in-line model, ensure the unit is bypassed or drained to prevent pressure buildup during winter months. Store the lid in a cool, dry place to prevent the O-ring from drying out. If you live in an area with extreme temperatures, consider removing the unit entirely if the plumbing configuration allows for easy disconnection, ensuring all openings are capped to prevent debris entry.

Managing Flow and Clogs

If you notice that chemical levels in your pool are inconsistent, the feeder flow rate may need adjustment or the internal components may be clogged. Check the control valve for proper operation and ensure the feeder is not obstructed by mineral scale buildup. Use a soft brush or a mild, manufacturer-approved cleaning solution to clear any debris from the inlet and outlet ports. Never use sharp metal tools to scrape the interior, as this can damage the chemical-resistant coating. If the flow remains restricted, inspect the supply lines for kinks or blockages. Consistent water testing is essential to verify that your adjustments are yielding the desired sanitation levels without over-chlorinating the pool water, which can damage equipment.

Component Replacement Schedules

The longevity of your rainbow bromine feeder depends on proactive component replacement. O-rings, check valves, and tubing are wear items that require periodic inspection and replacement to maintain a watertight system. Do not wait for a major leak to occur before replacing these parts. Keep a small stock of manufacturer-recommended replacement seals and tubing on hand for quick repairs. When replacing parts, only use components compatible with your specific model number to ensure a proper fit and safe operation.
