CCP420 Pool Filter Cartridges 4 Pack Replacement for Pentair CCP420 - for Clean and Clear Plus 420, PCC105-PAK4, for Unicel C-7471, R173576, for Filbur FC-1977, 570-0425, 420 sq.ft. L x OD: 26"x7"

The CCP420 replacement cartridges are a high-capacity filtration solution designed for those managing large above-ground pool systems. With a massive 420 square feet of media, this four-pack bundle provides extensive surface area to capture debris, ensuring consistent water clarity and reliable performance for demanding pool maintenance schedules.

These replacement cartridges are engineered to meet the technical specifications of the Pentair Clean and Clear Plus 420 system, offering a direct alternative to OEM parts. By utilizing a multi-cartridge design, the system distributes water flow effectively, which minimizes pressure buildup and extends the time between cleanings. The durable construction aims to withstand the rigors of continuous filtration cycles, making it a robust choice for seasonal pool owners. Buyers should verify their specific filter housing model and dimensions against these 26-inch by 7-inch specifications before purchase to ensure a proper, watertight seal within their existing filtration unit for optimal flow efficiency.

Practical fit

The primary advantage of this four-pack set is the precise engineering intended to match standard Pentair configurations. Because the dimensions are standardized, installation typically involves removing the old cartridges and seating these new ones firmly in the manifold. Users should inspect their internal filter housing O-rings and alignment pins during the swap to ensure the cartridges sit perfectly flush. If the cartridges do not seat correctly, the system may allow water to bypass the media, leading to poor filtration. Always verify that your specific filter housing supports 26-inch length cartridges to avoid potential height clearance issues during installation.

Tradeoffs and ownership

Owning a high-capacity system involves a greater maintenance burden when it comes time to clean the media. Since these cartridges are large, rinsing them thoroughly requires significant water pressure and time. While the 420 square feet of surface area provides excellent filtration, the sheer volume of pleats can trap stubborn algae or fine silt that is difficult to remove. Owners should weigh the convenience of long intervals between cleanings against the physical effort required to deep-clean four large cartridges. If you prefer a low-maintenance setup, ensure you have a dedicated space for rinsing these large components properly.

Buying guide

What to look for

Verify Exact Housing Compatibility

Before purchasing, confirm the specific model number of your existing filter housing. Compatibility is not universal, and even slight variations in dimensions or end-cap design can prevent a cartridge from sealing correctly. Always cross-reference the part numbers listed in your owner's manual with the product specifications provided by the manufacturer to ensure a perfect fit.

Assess Your Filtration Needs

Consider the total square footage of your pool and the volume of water being filtered. A larger pool requires a higher surface area filter to maintain clarity without constant cleaning. Check your pump's flow rate specifications to ensure the chosen cartridge can handle the volume of water moving through the system without causing excessive backpressure.

Evaluate Material Quality Standards

Look for high-quality, reinforced polyester media that can withstand the pressure of your pump. Durable end caps and a sturdy center core are essential for preventing the cartridge from collapsing under load. Read user feedback regarding the longevity of the pleats and the overall structural integrity of the filter under normal operating conditions.

Check Installation Complexity Levels

Evaluate whether you need a complete system or just a replacement cartridge. If you are replacing a full housing, ensure that the plumbing connections match your existing pipe size. For simple cartridge swaps, verify that no additional tools or adapters are required to achieve a secure, airtight seal within your current setup.

Review Manufacturer Warranty Policies

Check for information regarding warranties or guarantees provided by the manufacturer. While many cartridges are consumable items, a reputable brand will often stand behind the build quality of their products. Understand the limitations of these warranties, including requirements for proper maintenance and adherence to recommended chemical levels in the pool.

Understand Local Water Chemistry

The chemical balance of your pool water directly impacts the lifespan of your filter cartridge. High calcium levels or aggressive pH swings can prematurely degrade filter media. Always maintain your pool chemicals within recommended ranges to protect your investment and ensure that the cartridge performs as intended throughout its expected service life.

Analyze Long-Term Ownership Costs

Factor in the cost of replacement cartridges over the life of your pool. While some filters are cheaper upfront, they may require more frequent replacements. Calculate the total cost of ownership by considering the expected lifespan of the cartridge and the frequency of cleaning required to keep your pool water clear and safe.

Ownership guide

Setup, use, and maintenance

Regular Pressure Monitoring

Consistently monitor your pool filter pressure gauge to identify when the cartridge requires cleaning. A rise of 8 to 10 psi above the clean starting pressure usually indicates that the filter media is saturated with debris. Always turn off the pool pump before attempting to remove the filter housing or lid. Consult your system manual for specific safety procedures regarding pressure release valves to prevent injury during the opening process. Regular monitoring prevents excessive strain on your pump motor and ensures optimal water circulation throughout your pool system.

Proper Cartridge Cleaning Routine

When cleaning your cartridge, use a gentle stream of water from a garden hose to spray down the pleats. Start from the top and work your way down, ensuring all trapped dirt and organic matter are removed. Avoid using high-pressure power washers, as these can easily damage the delicate filter media and reduce its lifespan. If the cartridge remains discolored or clogged, consider using a pool-safe filter cleaner solution. Never mix different chemical cleaning agents, as this can create dangerous reactions. Always rinse the cartridge thoroughly before placing it back into the filter housing to prevent chemical contamination of your pool water.

Inspecting Seals and O-Rings

During every cleaning cycle, carefully inspect the filter housing O-rings and gaskets for signs of wear, cracking, or flattening. A compromised seal is a common cause of leaks and air ingestion, which can significantly hinder filtration performance. If you notice any damage, replace the O-ring immediately with a manufacturer-approved part. Applying a thin layer of silicone-based lubricant to the O-ring can help maintain a proper seal and make future lid removal much easier. Proper maintenance of these components is essential for preventing leaks and ensuring your filtration system operates at its peak efficiency throughout the entire swimming season.

Winterization and Storage Procedures

When preparing your pool for the off-season, remove the cartridge from the filter housing. Thoroughly clean and dry the unit before storing it in a cool, shaded, and dry location. Storing cartridges in direct sunlight or freezing temperatures can degrade the material and cause the pleats to become brittle. If the cartridge is nearing the end of its functional life, it is often better to discard it and purchase a fresh unit for the following spring. Always follow local guidelines for pool equipment storage and ensure that all housing components are drained of water to prevent damage from freezing.

System Troubleshooting Boundaries

If you experience persistent cloudy water or low flow rates after cleaning your filter, verify that the cartridge is properly seated and that there are no obstructions in the intake or return lines. If the filter housing lid is difficult to secure or continues to leak, check for debris in the threads or damage to the housing itself. Avoid attempting internal repairs to the pump or motor housing unless you are a qualified professional. If problems persist, consult your specific equipment manual or reach out to a certified pool technician to address potential mechanical issues before they lead to costly system failures.

FAQ

Above-Ground Pool Cleaners — FAQ

How do I know which cartridge fits my waterway filter?

Check the label on your existing filter housing for the model number. You can also measure the length and outer diameter of your current cartridge. Compare these dimensions and the part number against the specifications provided in the product listing. If you are unsure, consult your owner's manual or contact the manufacturer of your filter housing to confirm the exact replacement part required for your specific system.

Can I clean my filter cartridge with pool chemicals?

It is generally not recommended to clean cartridges with concentrated pool chemicals. Always follow the manufacturer's instructions regarding cleaning agents. If you use a dedicated filter cleaner, ensure it is thoroughly rinsed off before reinstalling the cartridge. Never mix different chemicals, as this can cause harmful reactions. Using harsh or improper chemicals can damage the filter media, significantly reducing its effectiveness and lifespan.

How often should I replace my pool filter cartridge?

Replacement frequency depends on usage, pool size, and water quality. Generally, a cartridge should be replaced every 12 to 24 months. If you notice that the filter pressure remains high after cleaning, or if the pleats appear frayed or damaged, it is time for a replacement. Regular cleaning extends the life of the cartridge, but eventually, the media will lose its ability to capture fine particles.

Is it better to buy a higher square footage filter?

A higher square footage filter typically allows for longer intervals between cleanings because it has more surface area to trap debris. If your housing supports it, upgrading to a larger cartridge can be beneficial for reducing maintenance time. However, ensure the cartridge fits your existing housing perfectly; a cartridge that is too large will not seal properly, allowing unfiltered water to bypass the filter.

Why is my pool water still cloudy after cleaning the filter?

Cloudy water can result from poor chemical balance, insufficient filtration time, or a damaged cartridge. Check your pH, alkalinity, and sanitizer levels first. If the water chemistry is correct, ensure the pump is running for enough hours each day. If the cartridge is old or damaged, it may no longer be effectively trapping fine debris, requiring a replacement to restore water clarity.

Can I use a pressure washer to clean my cartridge?

Do not use a pressure washer on pool filter cartridges. High-pressure water can tear the filter media and damage the pleats, rendering the cartridge ineffective. Always use a standard garden hose with a spray nozzle to gently rinse away debris. If the cartridge is heavily soiled, use a recommended filter cleaning solution and follow the instructions carefully to avoid damaging the integrity of the filter material.

What should I do if my filter housing leaks after a change?

First, turn off the pump and release the pressure. Remove the lid and inspect the O-ring for debris, twists, or damage. Clean the O-ring and the sealing surface of the housing. Apply a light coat of silicone-based lubricant to the O-ring before reseating it. If the leak persists, the O-ring may need to be replaced. Ensure the lid is tightened securely according to the manufacturer's instructions.

Does my filter need to be winterized?

Yes, if you live in an area that experiences freezing temperatures. Drain the filter housing completely to prevent water from freezing and cracking the plastic components. Remove the cartridge, clean it, and store it in a dry, indoor location. Following proper winterization steps is crucial for protecting your equipment from cold-weather damage and ensuring it is ready for use when the swimming season begins again.
