Buying guide

What to look for

Assessing Pool Capacity

Before purchasing, verify your pool's total gallon capacity. Every Hayward above ground pool filter is rated for a specific flow rate and volume range. Choosing a system that is too small will force you to run the pump longer, increasing energy costs and causing premature wear. Conversely, an oversized system may move water too quickly for the filter media to catch fine debris effectively. Always check the manufacturer's specifications to ensure the filter's turnover rate matches your pool size. If your pool is near the upper limit of a filter's rating, consider moving up to the next size to ensure better performance and less frequent maintenance cycles during peak summer months.

Evaluating Filter Media Types

Decide between sand, cartridge, or DE filtration based on your maintenance preferences. Sand filters are the most common and require simple backwashing, making them easy to manage for most owners. Cartridge filters offer superior filtration and are generally easier to clean, though the cartridges themselves must be replaced periodically. DE filters provide the highest level of water clarity but involve more complex maintenance and the handling of chemical media. Consider how much time you are willing to dedicate to weekly upkeep. If you prefer a 'set it and forget it' approach, sand is often preferred. If you want the clearest water possible and don't mind the extra effort, DE or high-quality cartridges are the best options.

Checking Plumbing Compatibility

Confirm the hose diameter and connection types used by your current pool setup. Most above-ground systems utilize standard flexible hoses, but some may require specific adapters to connect to a new Hayward above ground pool filter. Verify if your existing pump and filter are a single unit or separate components. If you are replacing only the filter, ensure the new tank's inlet and outlet ports align with your current plumbing layout to avoid expensive modifications. If your setup uses rigid PVC piping, you may need additional unions or couplings to complete the installation. Always measure your current connection points before ordering to ensure a seamless transition and to avoid the frustration of missing parts upon delivery.

Reviewing Space Requirements

Measure the physical footprint of your pool equipment pad. Some sand filter systems include a large base that requires a level, stable surface, such as a concrete pad or a sturdy, pressure-treated wood platform. Ensure there is enough clearance around the filter to allow for easy access to the multiport valve, the pressure gauge, and the drain plug. If your space is tight, a compact cartridge or a vertical sand filter might be more appropriate. Keep in mind that you also need space for the hoses to run without sharp bends, which can restrict flow and put unnecessary strain on the pump motor. Proper placement is essential for both ease of maintenance and long-term equipment safety.

Understanding Power Requirements

Check your electrical setup to ensure it can support the pump motor. Most above-ground pool pumps require a standard grounded outlet, but you must verify the voltage and amperage requirements listed on the pump motor plate. Never use an extension cord to power your pool pump, as this poses a significant safety risk. If you are uncertain about your electrical capacity, consult with a licensed electrician to ensure your outlet is GFCI protected and compliant with local building codes. Some higher-horsepower pumps may require specific circuit breakers. Always prioritize safety over convenience when dealing with electrical equipment near water, and ensure all installations meet local regulations regarding distance from the pool edge.

Considering Long-Term Ownership

Beyond the initial purchase price, consider the long-term costs of owning a specific filter system. Sand filters require periodic replacement of the sand media, typically every three to five years. Cartridge filters require the purchase of replacement cartridges, which can add up over time depending on how often they need changing. DE filters require the ongoing purchase of DE powder. Additionally, consider the availability of replacement parts like O-rings, gaskets, and pump seals. Hayward is a well-established brand, which generally makes finding replacement parts easier. Factor in these recurring costs when choosing your system to ensure you are comfortable with the ongoing financial commitment required to keep your pool water clean and safe throughout the season.

Manufacturer Support and Warranty

Research the warranty coverage and availability of support for the specific model you are considering. A solid warranty provides peace of mind, especially for the pump motor, which is the most expensive component of your system. Check if the manufacturer offers clear documentation or online troubleshooting guides for their products. Hayward typically provides extensive resources for their equipment, which can be invaluable for DIY owners. Verify if the warranty requires professional installation, as some manufacturers may void coverage if the system is not installed by a certified technician. Always keep your purchase receipt and registration information in a safe place, as you will need these if you ever need to file a claim or request technical assistance.

Ownership guide

Setup, use, and maintenance

Regular Backwashing Procedures

Maintaining a sand-based Hayward above ground pool filter requires consistent backwashing to remove trapped debris. When the pressure gauge indicates a reading 8 to 10 psi above the clean starting pressure, it is time to perform this routine. Always turn off the pump before moving the multiport valve handle. Set the valve to backwash, then run the pump until the sight glass shows clear water. This process prevents clogging and maintains optimal flow rates.

Cartridge Cleaning Best Practices

For cartridge-based systems, maintenance focuses on manual cleaning rather than backwashing. Periodically remove the cartridge and rinse it thoroughly with a garden hose, ensuring you reach between every pleat to dislodge algae and fine particles. Avoid using high-pressure washers, as these can easily tear the delicate filter media, rendering the cartridge ineffective. If the cartridge appears gray or feels oily despite rinsing, use a specialized pool-grade filter cleaner to break down organic buildup. Never use household detergents or soaps, as these can cause excessive foaming in your pool water.

Managing DE Filter Media

Diatomaceous Earth systems offer excellent filtration but require careful handling during maintenance. When the pressure rises, you must backwash the system according to the manufacturer's instructions. After backwashing, you must replenish the DE powder through the skimmer to coat the filter grids properly. Always wear protective gear when handling DE powder, as it is a fine substance that should not be inhaled. Ensure your system is completely shut down before opening the filter tank for any internal inspections. If the grids become heavily coated with oils or scale, remove them for a deep cleaning using a dedicated DE grid cleaner. Always consult your specific model manual for the exact amount of powder required, as over-charging can lead to excessive system pressure.

Winterization and Storage

Proper winterization is critical for protecting your Hayward above ground pool filter from freezing damage. Begin by draining the filter tank, pump housing, and all associated plumbing lines. Remove the drain plugs and store them in a secure place, such as the pump basket, so they are not lost during the off-season. If you live in an area with freezing temperatures, it is highly recommended to disconnect the pump and move it to a dry, climate-controlled environment. Ensure all O-rings are lubricated with a silicone-based lubricant before storage to prevent drying and cracking. Covering the remaining equipment with a breathable tarp can help protect the housing from UV damage and debris while the pool is closed for the winter months.

System Pressure Gauge Monitoring

The pressure gauge is the most important tool for monitoring your filter's health. You should record the 'clean' pressure reading immediately after installing a new filter or cleaning your media. Check this gauge at least twice a week during the swimming season. A sudden spike in pressure often indicates a blockage in the filter media, while a drop in pressure may suggest a clog in the skimmer basket or a suction-side air leak.

FAQ

Above-Ground Pool Cleaners — FAQ

How often should I backwash my sand filter?

You should backwash your sand filter when the pressure gauge reading increases by 8 to 10 psi over the clean, starting pressure. This typically happens every few weeks, depending on your pool's usage, debris levels, and the local environment. If you notice a significant decrease in water flow returning to the pool, it is also a sign that the filter needs cleaning. Always follow the specific instructions in your Hayward manual to ensure you are operating the multiport valve correctly. Never backwash more often than necessary, as the filter actually works slightly more efficiently when it has a small amount of trapped debris.

Can I use an extension cord with my pool pump?

No, you should never use an extension cord to power your pool pump. Pool pumps require a high amount of power, and extension cords are not designed to handle this load safely, which creates a serious fire hazard and a risk of electrical shock. The pump should be plugged directly into a dedicated, GFCI-protected outdoor outlet that meets local electrical codes. If your current outlet is not close enough, you must have a licensed electrician install a new, code-compliant outlet closer to the equipment pad to ensure safe and reliable operation of your Hayward above ground pool filter system.

What is the difference between sand and cartridge filters?

Sand filters use specialized pool sand to trap debris, requiring backwashing to clean the media. They are durable and require less frequent attention but offer a lower level of filtration fineness compared to other types. Cartridge filters use a pleated fabric element to trap particles, providing superior filtration quality and easier cleaning, as you simply remove and rinse the cartridge. However, cartridges eventually wear out and must be replaced, which is an ongoing cost. Sand is often preferred for its simplicity and longevity, while cartridge filters are chosen by those who prioritize water clarity and want a more straightforward, tool-free cleaning process.

How do I know if my pump is the right size for my pool?

To determine if your pump is the right size, you must first calculate your pool's total volume in gallons. Then, look for a pump and filter system that is rated to turn over your pool's entire volume of water in about 8 to 10 hours. If the pump is too small, it will struggle to keep the water clear and may require running for 24 hours a day, which is inefficient.

Is it safe to mix different types of pool chemicals?

No, you should never mix pool chemicals. Mixing incompatible chemicals, such as different types of chlorine or algaecides, can result in dangerous chemical reactions, including the release of toxic gases or even explosions. Always add chemicals to your pool water separately, following the specific instructions provided on the product labels.

Why is my pressure gauge reading high immediately after backwashing?

If the pressure remains high after a thorough backwashing, it may indicate that the sand media is dirty, hardened, or calcified, preventing proper water flow. In this case, the sand may need to be replaced. Alternatively, check for a clog in the multiport valve, the return lines, or the pool's return jets. Sometimes, a faulty pressure gauge can provide an inaccurate reading.

How do I winterize my filter system?

To winterize, first turn off the power to the pump. Open the drain plugs on the bottom of the filter tank and the pump housing to let all water escape. If your system has a multiport valve, set it to the winterize position if available. Remove the pump and store it in a dry, indoor location to protect it from freezing. Disconnect all hoses and drain them completely.

What should I do if my pump is leaking water?

A leak at the pump is usually caused by a worn-out mechanical seal, a cracked housing, or a damaged O-ring. First, inspect the area around the pump union and the lid O-ring, as these are common leak points. If the leak is coming from the center of the pump, the internal mechanical seal likely needs replacement.

Final verdict

Bottom Line

Selecting the right Hayward above ground pool filter requires balancing your pool's specific volume with the maintenance effort you are willing to invest. Whether you choose the rugged reliability of a sand system or the high-clarity performance of a cartridge or DE filter, prioritizing compatibility and proper sizing ensures a cleaner, safer swimming environment. Always follow local safety codes and manufacturer guidelines for the best results.

By staying consistent with your cleaning routines—such as monitoring pressure gauges and performing timely backwashing—you protect your investment and extend the life of your equipment. A well-maintained filter system is the heart of a healthy pool, providing the circulation and filtration needed for season-long enjoyment.
