When to Replace Cartridge Pool Filter

If you own a pool, you know that keeping it clean and clear is crucial for swimmers’ health and enjoyment. A pool filter is a crucial element in any pool cleaning and maintenance system. Cartridge pool filters are popular for their efficiency and ease of use. However, over time, these filters can become worn out, hampering their performance. So, what are the signs that your cartridge pool filter needs replacing? Read on to find out.

1. The Pressure Gauge is Reading High

The pressure gauge on your pool’s filter system measures the pressure inside the filter. A reading of 10-15 PSI (pounds per square inch) means that the system is working correctly. However, if the reading is above 20 PSI, it’s time to check the filter. An overly high reading indicates that the filter is clogged, hindering the water’s flow through it. Cleaning the filter might help extend its lifespan, but if the pressure reading remains high even after cleaning, it’s time to replace the cartridge pool filter.

2. The Filter is Damaged

Cartridge pool filters are pretty durable, but like anything, they are not indestructible. Over time, the filter media can become brittle or break apart, leaving gaps in the filter. These damage spots cause debris to pass through the filter and back into the pool. If you notice small rips or tears in the filter media, it’s best to replace the filter element. Oftentimes, replacing the cartridge pool filter is cheaper than continually replacing individual parts.

3. Water Quality is Poor

If your pool starts to look cloudy or green, it could be a sign of a dirty filter. A cartridge pool filter that has stopped working correctly will no longer be able to clean your pool’s water adequately. When the filter’s fibers are clogged with dirt and debris, it can no longer trap particles, leading to poor water quality. If you find that your pool water is not as clean as it usually is, replacing the filter cartridge can help restore it to its former glory.

4. Minimal Water Flow

Another warning sign that it’s time to replace your pool filter cartridge is a reduced water flow. When the filter is clogged, the water flow from the jets is often affected. A filter that’s clogged with dirt is more difficult for water to pass through, leading to a reduced water flow. If you notice weaker or minimal water flow coming through the jets, it’s a sign that the filter needs replacing. A new, clean cartridge pool filter restores the water flow’s strength and speed, making the pool more enjoyable to swim in.

5. Age of the Filter

Lastly, aging is a critical factor in determining when your cartridge pool filter should be replaced. Although there’s no hard and fast rule, most cartridges last between two and three years. Depending on the size of your pool and the number of swimmers, it may wear out sooner or last longer. It’s recommended that pool owners inspect the filter every six months to determine if it needs cleaning, maintenance, or replacing.

In conclusion, a cartridge pool filter is an essential part of any pool maintenance system. It works by trapping dirt and debris, ensuring that your pool stays clean and safe for swimming. Knowing when to replace your cartridge filter can help maintain your swimming pool and electronic equipment’s efficiency while prolonging its life. If you spot any of the warning signs mentioned above, it’s time to replace your filter cartridge without delay. By doing so, you can keep your pool clean, clear, and healthy for years to come.
