Sanitization System Parts

Shop Reliable Pool Sanitization Parts, Pool Chlorinator Parts, and More

Maintaining a crystal-clear pool shouldn't feel like a full-time job, but it does require a robust sanitization system. Whether you’re running a classic chlorine feeder or a high-tech salt system, these components are your pool’s immune system. They work 24/7 to kill bacteria and algae before they take hold. Because they live in a world of concentrated chemicals and high pressure, small parts like seals and sensors eventually wear down.  Having the right pool sanitization parts on hand is the difference between a relaxing swim and a frantic trip to the store to fix a green pool.

Fresh Pool Supply’s selection of pool chlorinator parts and salt-system replacement parts values durability and usability. From the tiniest O-ring to heavy-duty replacement cells, our gear is built to serve busy commercial aquatic centers and neighborhood family pools alike. A little proactive maintenance, like replacing a worn gasket for a few dollars, keeps your water safe and prevents your pool pumps from straining against air leaks or clogs.

Explore Top Parts for Chemical Feeder Repairs

Automatic chemical feeders, like the popular Pentair Rainbow 300 and Hayward CL200, are incredibly reliable until they aren't. Most issues with these units stem from three main components:

• Chlorinator Lid: Constant exposure to chlorine gas makes lids brittle. If you see cracks or if the lid is stuck, it’s time for a swap.

• Feeder Control Knob: This lets you dial in your chlorine levels. If it becomes hard to turn, the internal assembly may be corroded.

• O-Rings and Gaskets: These are the most common causes behind "air leaks." If your pump is struggling to prime, a worn chlorinator lid O-ring is often the hidden cause.

Find Cells, Switches, and Unions for Your Salt System Maintenance

Saltwater pools are loved for their silky feel, but the "cell" is a high-tech component that requires specific salt-system replacement parts to function.

• Salt Cell Flow Switch: If your system says "No Flow" but your pump is running, the flow switch is likely broken. Replacing just the switch is a much cheaper alternative to replacing the entire system.

• Unions and Seals: Salt is corrosive. If you notice white, crusty buildup around your plumbing connections, your unions probably need new seals to prevent slow drips.

• Cell Cleaning: Clean your cell quarterly to remove calcium scale and extend its lifespan.

Troubleshooting Leaks: Where is the Water Coming From?

Finding a puddle under your equipment? Chemical feeder repair usually boils down to two areas:

1. Bottom Leaks: If water is leaking from the base of a feeder, check the check valve assembly. This prevents concentrated chlorine from backing up into your heater and pump when the system is off.

2. No-Draw Issues: If your pool chemicals aren't going down, look for clogged tubing or a failed control valve.

Brand Compatibility Guide: Pentair, Hayward, and Jandy

Frequently Asked Questions

1. Why is my pool chlorinator lid hard to open?

Chlorine gas is incredibly harsh; it causes the rubber O-ring to swell and the plastic threads to "lock" over time. Regularly lubricating the O-ring with a silicone lubricant, never petroleum-based, which degrades rubber, will keep the seal pliable and make the lid a breeze to open during your weekly chemical check.

2. How often should I replace the check valve in my feeder?

We recommend replacing the check valve assembly every 1–2 years as part of your routine maintenance. This tiny, inexpensive part is your system's primary defense; it prevents highly concentrated chemical water from backing up into your expensive heater and pump, which can cause internal corrosion and costly plumbing failures.

3. Can I replace just the flow switch on my salt cell?

Absolutely. Many pool owners mistakenly think they need a whole new cell when they see a "No Flow" error light. In many cases, the cell is perfectly fine and only the flow switch has failed. Replacing just the switch is a simple, cost-effective fix that saves you hundreds of dollars.

4. What parts do I need if my chlorinator leaks water?

First, inspect the lid O-ring for cracks or flattening, as this is the most common leak point. If the water is settling at the bottom, you likely need a replacement check valve or new threaded fittings. Always check your tubing for pinhole leaks caused by long-term sun exposure and chemical wear.

5. Are Hayward and Pentair feeder parts interchangeable?

Generally, no. While Hayward and Pentair systems perform the same basic function, they use proprietary thread patterns, diameters, and connection styles. Using the wrong part can cause dangerous leaks or poor chemical distribution. To ensure a safe, airtight fit, always match the replacement part to your specific brand and model number.
