Buying guide

What to look for

Verify Your Pump Model Number

Before purchasing any filter or accessory, always confirm your specific pump model number. Bestway offers a wide range of pumps, and while many parts appear similar, they are not always interchangeable. Check the label on your pump housing to identify the exact model and the required cartridge type, such as Type II or Type III/A. Relying on visual similarity alone can lead to poor fits and inefficient filtration. If you are unsure about compatibility, consult the manufacturer’s documentation or the product listing details. Taking a moment to verify these specifications ensures you receive the correct components, preventing the frustration of returns and ensuring your pool system operates at its intended performance level from the very first day of installation.

Assess Your Pool Volume Requirements

The 800 gallon pump rating is a baseline for performance, but your pool’s total volume should guide your purchase. If your pool is on the higher end of the 800-gallon capacity, you may need more frequent filter changes to maintain clarity. Conversely, smaller pools may find that standard cartridges last longer. Always consider the manufacturer's recommended pool size range for your pump. If your pool volume exceeds the pump's capacity, you might experience poor circulation and water quality issues. In such cases, consider upgrading to a higher-capacity system rather than relying on a pump that is undersized for your needs, as this will save you time and money on chemical treatments and maintenance.

Consider Long-Term Ownership Costs

When comparing pump options, look beyond the initial purchase price. Cartridge pumps are generally cheaper upfront but require regular replacement of disposable filters, which adds up over time. Sand filters have a higher initial cost but offer a lower cost of ownership in the long run, as the sand media lasts for several seasons. Factor in the cost of replacement parts like O-rings and hoses as well. Understanding the total cost of ownership helps you choose the right system for your budget and maintenance preferences. A more expensive pump that requires less frequent intervention may ultimately be more economical and provide a better experience for the pool owner.

Evaluate Filtration Media Options

Decide between cartridge and sand filtration based on your maintenance tolerance. Cartridge filters are simple to install and replace, making them ideal for beginners or those with limited time. However, they must be cleaned and replaced frequently. Sand filters provide a more robust filtration method but require more initial setup and knowledge of backwashing procedures. Think about how much time you are willing to dedicate to manual cleaning versus the convenience of a system that handles debris more autonomously. Both options are effective when sized correctly for your pool, so the choice ultimately comes down to which maintenance routine fits your lifestyle and your specific pool setup.

Check Compatibility With Existing Hoses

Ensure that any new pump or accessory you purchase is compatible with your existing pool hoses and connection fittings. Bestway systems often use standard hose sizes, but variations can exist between different models and regional versions. Before finalizing your purchase, verify the diameter of your intake and outlet ports. If you are upgrading your pump, you may need to purchase additional adapters or new hose sets to ensure a secure, leak-free connection. Avoiding this check can lead to significant delays during setup. Always prioritize a system that integrates seamlessly with your current pool configuration to minimize the need for custom plumbing or additional hardware modifications.

Review User Feedback and Ratings

While professional reviews provide guidance, user feedback offers valuable insights into real-world product performance. Look for recurring themes in reviews, such as ease of installation, durability of materials, and common troubleshooting issues. Pay attention to feedback regarding compatibility with specific 800 gallon pump models. If multiple users report the same issue, it is a sign to investigate further before buying. However, keep in mind that individual experiences can vary based on pool conditions and maintenance habits. Use these ratings as a supplement to the official product specifications, focusing on patterns rather than isolated incidents to make an informed decision that aligns with your expectations for quality and reliability.

Prioritize Manufacturer-Recommended Parts

When replacing components like filters or seals, prioritize parts that are designed specifically for your Bestway pump model. Third-party alternatives may be available, but they do not always meet the exact dimensional or material specifications of the original equipment. Using manufacturer-recommended parts ensures optimal fit and performance, reducing the risk of leaks or filtration bypass. While these parts may sometimes carry a premium, the peace of mind and protection of your pump’s warranty are worth the investment. Always check the product listing for compatibility statements to confirm that the part is intended for your specific pump series, ensuring that your maintenance efforts result in a clean and safe swimming environment.

Ownership guide

Setup, use, and maintenance

Regular Filter Cleaning Routines

Maintaining your Bestway 800 gallon pump system starts with a consistent cleaning schedule for your filter cartridges. For Type III/A or Type II cartridges, remove the filter weekly and rinse away debris using a garden hose. Inspect the pleats for signs of wear, such as fraying or permanent discoloration, which indicate that a replacement is necessary. Never use harsh pressure washers, as these can damage the delicate filter media and compromise filtration efficiency. If you are operating a sand filter, follow the manufacturer's backwash schedule to clear trapped contaminants.

Monitoring Seal and O-Ring Health

Pump leaks are frequently caused by worn or misaligned O-rings. Regularly inspect all connection points on your 800 gallon pump for signs of moisture. If a leak is detected, turn off the system and examine the O-ring for cracks, debris, or flattening. A clean, well-lubricated O-ring is essential for maintaining the airtight seal required for optimal pump suction. When replacing seals, ensure the new component matches the exact specifications of your pump model to prevent further leaks. Avoid over-tightening connections, as this can crack the plastic housing or damage the seals themselves. By keeping spare O-rings on hand, you can quickly address minor issues, preventing them from escalating into significant equipment failure or water loss during the busy swimming season.

Sand Filter Backwash Best Practices

For those upgrading to sand filtration, understanding the backwash cycle is crucial for longevity. Monitor the pressure gauge on your filter; when the pressure rises significantly above the normal operating range, it indicates that the sand bed is saturated with debris. Perform a backwash to reverse the water flow, flushing captured particles out through the waste port. Always follow the specific instructions in your owner's manual regarding valve positioning. Ensure that the waste hose is directed safely away from the pool and local drainage areas.

Winterization and Seasonal Storage

Proper storage is essential to protect your pump components during the off-season. Before winter, disconnect the pump from the pool and drain all water from the housing to prevent freezing damage, which can crack the plastic casing. Remove the filter cartridge or sand media, clean the housing thoroughly, and allow it to air dry completely. Store the pump and all hoses in a dry, climate-controlled environment to prevent degradation of seals and plastic parts. If you are using a sand filter, ensure the tank is drained and the multiport valve is set to the winterize position. Taking these steps ensures that your equipment remains in good working order, ready for a seamless setup when the next swimming season begins.

Electrical Safety and Pump Care

Always prioritize electrical safety when maintaining your pool pump. Ensure that your pump is connected to a GFCI-protected outlet as required by local electrical codes. Never attempt to service the pump while it is plugged in. If you notice any fraying on the power cord or signs of moisture near electrical components, discontinue use immediately and consult a qualified professional. Keep the area around the pump clear of standing water and debris to prevent short circuits.

FAQ

Pool Maintenance — FAQ

How often should I replace my 800 gallon pump filter?

The frequency of filter replacement depends on usage, pool environment, and water quality. Generally, you should inspect your filter weekly. If the pleats appear clogged, discolored, or damaged, it is time for a replacement. For moderate use, a cartridge may last two to four weeks. Always keep a spare on hand so you can swap it out immediately when needed. If you notice a significant drop in water flow, check the filter first, as a saturated cartridge is the most common cause of reduced pump efficiency.

Can I use a sand filter with my existing pool?

Yes, many above-ground pools are compatible with sand filter upgrades, provided the pump capacity matches your pool size. The 58516E sand filter is designed for a range of pool volumes, including those typically served by 800 gallon pumps. However, you must ensure your existing hoses and connections are compatible or be prepared to purchase necessary adapters. Always verify your pool's total gallon capacity against the sand filter’s specifications before making the transition to ensure it provides sufficient circulation for your specific setup.

What should I do if my pump is leaking?

First, turn off the pump and disconnect it from the power source to ensure safety. Locate the source of the leak, which is often at a connection point or the filter housing lid. If the leak is at a fitting, check the O-ring for damage or debris. Cleaning or replacing the O-ring with a compatible part often resolves the issue. If the housing itself is cracked, the unit may need to be replaced. Never attempt to patch cracks with non-approved sealants, as these will not withstand the internal pressure of the pump system.

Are all Type II filters the same size?

While Type II filters are designed to fit specific Bestway pump models, it is crucial to verify the dimensions and compatibility listed for your pump. Not all filters labeled as Type II are identical in quality or exact fit across different manufacturers. Always check the listing for your specific pump model number or reference your owner's manual to ensure you are purchasing the correct size. Using an improperly sized filter can lead to bypass, where water flows around the filter rather than through it, significantly reducing your pool's cleanliness.

How do I know if my pump is undersized?

An undersized pump will struggle to circulate the entire volume of your pool effectively, often resulting in cloudy water, algae growth, or debris accumulation even with regular chemical treatment. If you find that your pump must run for an excessive number of hours to achieve clarity, or if you are constantly cleaning the filter, your pump may be too small for your pool's capacity. In these instances, upgrading to a higher-capacity pump or a sand filtration system is often the most effective solution for long-term water quality.

Is it safe to use third-party filter replacements?

Third-party filters can be a viable option, but their performance and fit can vary significantly. To ensure the best results, look for products that explicitly state compatibility with your specific Bestway pump model. Check user reviews to see if others have had success with the fit and filtration quality. While they may be more affordable, always prioritize products that demonstrate a commitment to the correct dimensions and material standards to avoid potential damage to your pump or inefficient water filtration.

What is the benefit of a sand filter over a cartridge?

The primary benefit of a sand filter is its longevity and reduced maintenance frequency. While cartridge filters require frequent cleaning and replacement, sand media can last for several seasons before needing a change. Sand filters also provide a more consistent filtration rate as they do not clog as quickly as cartridges. However, they do require an understanding of the backwash process. For pool owners who want to minimize the time spent on manual filter maintenance, a sand filter is often considered the superior, albeit more involved, long-term choice.

Should I add chemicals directly into the pump?

No, you should never add pool chemicals directly into the pump or filter housing. Doing so can cause severe damage to the pump’s internal components, including the impeller and seals, and may lead to dangerous chemical reactions. Always follow the manufacturer's instructions for chemical application, which typically involves adding them directly to the pool water while the pump is running to ensure proper distribution. Consult your pool chemical labels and your pump owner’s manual for the correct, safe procedure to maintain your pool's water chemistry without risking equipment failure.

Final verdict

Bottom Line

Choosing the right maintenance equipment for your Bestway 800 gallon pump requires a balance between initial cost and long-term convenience. Whether you opt for the simplicity of frequent cartridge swaps or the durability of a sand filter upgrade, the key is matching the product to your pool's specific volume. Always verify compatibility to ensure your system remains efficient and leak-free throughout the season.

Effective pool ownership is built on consistent routines, from cleaning filters to inspecting seals. By prioritizing manufacturer-recommended parts and following safe operating procedures, you can significantly extend the life of your pump. Focus on steady, preventative maintenance rather than reactive repairs, and you will enjoy a cleaner, safer swimming environment while maximizing the value of your chosen pool equipment.
