Complete Guide to Hayward Pool Filters for Crystal Clear Water

 

If your pool water isn’t moving properly, things can get messy pretty quickly. Warm and stagnant water makes it easy for algae and bacteria to build up before you know it. While chemicals treat the water, your filter removes the debris and particles that make it look cloudy or dirty.

That’s why high-quality pool filtration systems like the Hayward DE2420 and the Hayward cartridge filter do more than keep your water looking clear. They help remove the debris and fine particles that affect water quality, so your pool stays cleaner and safer for swimming. If your pool uses either type, it’s important to know how to clean them so it can do their jobs properly.

Here’s a guide that tells you everything you must know about Hayward pool filters, from how they work to their maintenance. Whether you have a Hayward DE2420 or a smaller cartridge setup, understanding how your equipment works can make pool maintenance a whole lot easier while helping you keep the water cleaner and clearer.

How do Hayward pool filters work?

There are three primary types of Hayward filters. While each system operates differently, they all share the same purpose, and that is to remove unwanted particles from your pool water.

Cartridge filters

With cartridge filters, you get a filtration system that uses a pleated cartridge to catch dirt and debris as water passes through it. It’s like a large filter with tons of surface area designed to trap all the unwanted stuff floating around in your pool.

As the cartridge collects more debris, pressure inside the system starts to rise. When that happens, you need to clean your Hayward cartridge filter. Simply remove the cartridge and rinse it off with a hose before putting it back in.

You may appreciate the Hayward cartridge filter because it filters very well and runs quietly. Plus, it doesn’t waste water through backwashing. You just need to clean your Hayward cartridge filter manually on a regular basis to keep everything running properly.

Sand filters

In a sand filter, there’s a tank filled with specially graded pool sand to catch dirt and debris. As the pool water flows through the sand bed, the sand traps unwanted particles before the clean water gets sent back into the pool.

Over time, you’ll see the pressure rising as all that debris starts building up inside the tank. That’s your cue to backwash the filter by reversing the water flow to flush all the trapped debris out of the system.

The great thing about a sand filter is its reliability, especially when you have a large pool at home. Plus, they’re easy to maintain.

DE filters (diatomaceous earth)

With DE filters like the Hayward DE2420, you get the finest filtration out of the three main filter types. They use filter grids coated with diatomaceous earth, which is a very fine powder made from fossilized algae.

That powder is incredibly effective at catching tiny particles, often as small as 2 to 5 microns, which is why DE filters are more effective at keeping your pool water extra clear.

That said, you need to maintain them more regularly by backwashing the system and topping up the DE powder afterward to keep your filter working properly.

How do you clean a Hayward sand filter?

When the pressure rises about 8 to 10 PSI above its normal baseline or the water flow gets weaker, that's your sign to clean your Hayward sand filter.

·     Turn off the pump and set the valve to backwash.

·     Run it until the wastewater looks clear.

·     Switch to rinse for a short cycle, and then return the valve to the filter.

How do you clean a Hayward filter cartridge?

Keeping up with routine maintenance helps your Hayward filter run more efficiently and can help the system last longer, too. If you have a cartridge filter, clean it every two to four weeks, depending on how often the pool gets used and how much debris ends up in the water.

The good news is that you can easily clean a Hayward filter cartridge on your own. Just remove the cartridge and rinse it thoroughly with a hose. Once it’s clean, put it back into the system.

How do you clean a Hayward DE filter?

You need to backwash your Hayward DE2420 when the pressure rises about 8 to 10 PSI above its normal baseline.

·     Turn off the pump.

·     Set the valve to backwash, then run it until the water looks clear.

·     Switch to rinse if your system has that setting.

·     Return the valve to filter.

·     Add the required amount of fresh DE powder through the skimmer once the pump is primed again.

·     Take the filter apart for a deeper clean about once a year.

FAQs

How many hours should I run a Hayward filter?

For most pools, running the Hayward pump and filter for about 8 to 12 hours a day is usually enough. The exact amount of time depends on things like your pool size and how often people are swimming.

A good rule is to make sure the system circulates all your pool water at least once each day. During hotter months or times when the pool gets used more often, you may need to run the system a little longer to keep the water clean and clear.

How do Hayward pool filters work?

Your Hayward pool filter works by pulling water through the pump and sending it into the filter tank. Inside the tank, you’ll find the filter media that traps dirt and other unwanted particles before the clean water gets sent back into the pool through the return jets.

To keep everything working properly, be sure to clean your Hayward cartridge filter or sand or DE filters regularly, and backwash when necessary.

How do I know if the pool filter is working properly?

You can usually tell your pool filter is working well when the water stays clear, and the PSI stays within its normal range. Plus, the return jets have strong water flow.

If you see the pressure climbing too high, your filter probably needs cleaning. Cloudy water or reduced flow from the return jets can also mean that your filter is clogged or there’s another issue somewhere in the system.
