How to Change Your Pool Filter Without Losing Water

Maintaining your pool is essential to ensuring your family's safety and enjoyment. One critical component of the pool's maintenance is changing the filter. While this task may sound daunting, it is relatively straightforward, even for a beginner. What's more, you can do it without draining your pool. In this article, you'll learn how to change your pool filter without losing water.

Why Should You Change Your Pool Filter?

Your pool filter has the crucial job of removing contaminants, such as dirt, debris, and bacteria, from the pool water. When the filter becomes clogged, it will no longer function efficiently, leading to cloudy and unhealthy water. Furthermore, a dirty pool filter will cause your pool equipment, such as the pump and heater, to work harder, decreasing their lifespan.

When Should You Change Your Pool Filter?

Most experts recommend changing your pool filter at least once a year. However, the specific duration depends on your pool's frequency of use and the usage intensity. If the filter becomes clogged before the year-end, you may need to change it more frequently. Alternatively, a filter that remains clean may last longer than a year.

Gather Your Tools

Before changing your pool filter, gather all the necessary tools. These may include a replacement filter, pipe wrench, screwdriver, bucket, towel, and plumbing tape.

Turn Off the Pool Equipment

To avoid any mishaps, turn off the pool equipment, including the pump, heater, and any other filter components.

Release the Pressure

Your pool filter can withstand considerable pressure when in use. Before beginning the replacement, release this pressure by opening the air release valve or removing the pressure gauge. Additionally, remove the drain plug, typically located at the bottom of the filter, to release any remaining water.

Remove the Old Filter

Before removing the old filter, take a picture of the plumbing system to use as a reference when installing the new filter. Then, use the pipe wrench to loosen the filter's bolts, and unscrew the joints if necessary. Save the old gasket if it's in good condition; otherwise, replace it with a new one.

Install the New Filter

Carefully install the new filter, making sure it sits straight and central. Ensure that the filter's lid O-ring is correctly seated to prevent leaks. Replace any damaged or worn-out gaskets with new ones, and tighten the bolts firmly.

Reconnect the Plumbing

Refer to the picture taken earlier to reconnect the filter's plumbing system correctly. Turn on the pump and check for any leaks.

Final Thoughts

Changing your pool filter is a task that will keep your pool clean and healthy while extending the life of your pool equipment. With the right tools and a little guidance, you can accomplish this task without losing any water. Remember to change your filter at least once a year or as needed, and learn how to clean and maintain it properly to keep your pool at its best.
