FAQ

Pool Maintenance — FAQ

Can I install an in-line feeder myself?

Whether you can perform a DIY installation depends on your experience with PVC plumbing. In-line models require cutting into your existing return line, which involves precise measurements and secure gluing. If you are comfortable with these tasks, it is possible; however, if you are unsure, hiring a professional is recommended to prevent leaks and ensure the system operates under correct pressure. Always check your local building codes and the manufacturer manual before starting any plumbing work to ensure your installation remains safe and compliant.

How often should I refill the chlorine tablets?

The frequency of refilling depends on your pool size, the local climate, the water temperature, and the usage of the pool. Generally, you should check the feeder once a week to monitor the tablet levels. High-capacity feeders (9 lbs) will require less frequent attention than smaller units. Keep a log of your usage during the first few weeks of the season to establish a pattern, which will help you predict when the next refill is necessary to keep your chlorine levels stable and effective.

Is it safe to mix different types of chlorine tablets?

No, you should never mix different types of chlorine tablets or other pool chemicals inside your feeder. Combining incompatible chemicals can lead to dangerous chemical reactions, including the release of toxic gases or even explosions. Always use the specific type of chlorine recommended by the manufacturer in your manual. If you decide to switch types, ensure the feeder is completely empty and thoroughly cleaned of all residue from the previous chemical before adding the new product to the canister.

Why is my feeder leaking at the lid?

A leak at the lid is often caused by a worn or dirty O-ring. Inspect the O-ring for any cracks, debris, or flattening. Clean the area thoroughly and apply a thin layer of pool-safe lubricant to the O-ring to improve the seal. If the O-ring appears damaged, replace it immediately. Also, ensure the lid is tightened correctly—do not overtighten, as this can crack the plastic housing. If the leak persists, check the threads on the canister for any damage or buildup that might prevent a proper seal.

What is the difference between in-line and offline feeders?

An in-line feeder is plumbed directly into your return line after the filter, meaning all water passes through the unit. This is a permanent, integrated solution. An offline feeder is installed externally and connects to the plumbing using small flexible tubes, pulling a small amount of water through the feeder and returning it to the main line. Offline models are generally easier to install and are excellent for existing pools where cutting into the main return pipe is not feasible or desired.

Can I use this feeder for above-ground pools?

Some models are specifically designed for both in-ground and above-ground pools, while others are strictly for in-ground use. Always verify the compatibility listed by the manufacturer. Above-ground pools often have different plumbing sizes and pump pressures, so using an incompatible unit can lead to poor performance or leaks. If a model is labeled as compatible with both, ensure your pump and plumbing meet the minimum requirements outlined in the product manual before proceeding with the installation.

How do I clear a clog in the feeder?

If your feeder is not dispensing chlorine, it may be clogged with mineral buildup or tablet fragments. Turn off the pool pump and isolate the feeder from the plumbing system. Open the unit and remove any debris or partially dissolved tablets. Use a soft brush to clean the intake and output ports. If the clog is severe, you may need to flush the lines with fresh water. Never use metal tools that could scratch or damage the internal plastic components. Once clear, reassemble and test for proper flow.

What should I do during the winter?

During the off-season, you must winterize your feeder to prevent damage from freezing temperatures. Drain all water from the canister, remove any remaining chlorine tablets, and rinse the interior thoroughly. Leave the lid open or removed to allow the unit to air dry completely, which prevents mold and moisture buildup. If the feeder is installed in an area exposed to extreme cold, consider removing it and storing it in a protected, dry location. Inspect all seals and the housing for cracks before re-installing the unit when you open the pool for the next season.
