Introduction:

A pool filter plays an important role in maintaining the cleanliness of a swimming pool. The filter helps to remove dirt, debris, and other contaminants from the water. The cartridge pool filter is one of the popular types of filters used in swimming pools. One question that often arises is whether you can backwash a cartridge pool filter. This article will provide a detailed answer to this question.

Understanding the Cartridge Pool Filter:

Before we dive into the question of whether you can backwash a cartridge pool filter, it is essential to understand how this filter works. Unlike sand filters, cartridge pool filters use a replaceable filter cartridge made of pleated polyester or other types of materials to trap dirt and debris. The water flows into the filter cartridge, passing through the pleats, and coming out clean on the other end.

Can You Backwash a Cartridge Pool Filter?

The answer is no! You cannot backwash a cartridge pool filter. Backwashing is a cleaning process that removes dirt from sand filters by reversing the water flow. However, this process is not suitable for cartridge filters because backwashing can damage the filter cartridge's pleats, reducing its effectiveness. Once the pleats of a cartridge filter are damaged, the filter will no longer be able to catch small debris that can result in dirty and cloudy water. Therefore, it is essential to clean cartridge pool filters properly.

Cleaning a Cartridge Pool Filter:

Cleaning a cartridge pool filter is easy, and you don't need to backwash it. Here are the steps to follow:

Step 1: Turn off the pool pump and close any valves in and out of the filter.

Step 2: Remove the filter cartridge by unscrewing the filter housing's top or bottom with a wrench.

Step 3: Rinse off the filter cartridge with a hose or use a filter cleaning solution specific to cartridge filters. Make sure to rinse thoroughly and avoid using a power washer, as it can damage the pleats.

Step 4: Reinstall the filter cartridge, ensuring that it is evenly placed and secured in the filter housing.

Step 5: Turn on the pool pump and let it run for a few minutes to ensure that the water flows smoothly and that no leaks occur.

How Often to Clean a Cartridge Pool Filter:

How often you need to clean a cartridge pool filter depends on how often you use your pool, the number of swimmers, and the surrounding environment. Generally, it is recommended to clean the filter cartridge at least once per month or anytime the filter pressure rises ten psi above the starting pressure. A dirty filter cartridge will reduce water flow, reduce the filter's ability to catch debris, and can lead to an unclean pool.

Conclusion:

In summary, a cartridge pool filter is a common type of filter used in swimming pools. It is not suitable for backwashing because this process can damage the filter cartridge's pleats. Instead, properly clean the filter cartridge by rinsing it off with a hose or using a cartridge filter cleaning solution. Follow the steps above to properly clean your cartridge pool filter, and remember to clean it regularly to ensure a clean and healthy swimming pool.
