A backyard swimming pool is a great way to beat the heat during summertime. But, keeping your pool water crystal clear and free of debris requires consistent maintenance. One of the essential components of a pool system is the filter. As time passes by, the filter will become clogged with dirt, leaves, and other unwanted substances, affecting the circulation of water. It's crucial to change your pool filter at least once per year or as necessary. In this article, we'll show you how to change a Hayward pool filter in a few simple steps.


1. Understand the Hayward pool filter operation


Before diving in, it's essential to understand how Hayward pool filters work. The Hayward filter system circulates pool water through a tank, where it's filtered and cleaned before returning to the pool. The filter's job is to trap contaminants while allowing cleaner water to pass through using a filtration media.


Hayward pool filters have three types: sand, cartridge, and diatomaceous earth (DE). Sand filters utilize sand to remove impurities using a backwashing process. Cartridge filters contain an element that filters out debris, and DE filters utilize a powder filtration media. Depending on your pool usage and filter type, the frequency of servicing your filter would vary, but it's good practice to do so once a year.


2. Gather the necessary tools


Changing your pool filter isn't rocket science, but you'll need some tools before you start. Here's a list of what you'll need:


- Replacement filter cartridges/sand/DE

- Wrench

- Lubricant

- Pliers

- Pool skimmer or vacuum

- Garden hose


3. Turn off the pool filter


Safety first. Turning off the pool filter is crucial to avoid any electrical hazards. The on/off switch is located on the filter housing or pump, depending on your pool system.


4. Drain the filter


Assuming you have a sand or DE filter, you'll need to drain it before removing it. Open the air bleeder valve, which is typically located on the filter's top, and wait for the water to drain out. If you have a cartridge filter, there's no need to drain it.


5. Open the filter's housing


Next, locate the filter's housing band clamp and use a wrench to unscrew it. Be careful when removing the lock ring, as it can be challenging to unscrew, especially if it's been a while since it was last serviced. You may need some pliers to assist in unscrewing the lock ring.


6. Remove the old filter


After removing the lock ring, you can now access the filter cartridge/sand/DE. Pull the filter element upwards and take it out of the housing. If you're unsure what type of filter element you need, consult your owner's manual or a pool supply store.


7. Clean the filter housing


Before installing the new filter, remember to clean the housing using a hose. Inspect it for any cracks or damages that could render it ineffective. If there is any damage, replace it before installing the new filter.


8. Install the new filter


Align the filter element in its place and reattach the housing. Tighten the band clamp to seal the filter's housing, ensuring that the filter is centered in the housing. If you have a sand filter, ensure that you put the right amount of sand in the filter housing, so consult your owner's manual on the amount of sand needed.


9. Lubricate the O-ring


Take industrial lubricant and apply it to the filter's O-ring. This lubrication would prevent the O-ring from drying out and cracking, ensuring a tight seal.


10. Turn on the pool filter


Once you've assembled everything back and confirmed there is no leakage, turn on the pool filter. Check that the water flow and pressure are okay, and the filter is operating correctly.


In conclusion, servicing your pool filter is an essential part of pool maintenance, and it's relatively straightforward to do. Changing your Hayward pool filter can save you money in the long run by ensuring optimal pool performance while preventing hazardous pool conditions.
