Why Pool Filter Pressure Is High?

If you own a swimming pool, then you know that maintaining its cleanliness is of utmost importance. One of the most crucial factors in keeping your pool water clear and healthy is the pool filter. The pool filter is responsible for trapping debris, dirt, and other contaminants in the water to prevent them from entering the pool. However, there are times when the pool filter pressure is high, and it can be confusing for pool owners to understand why this is happening. In this article, we will explore several possible reasons why pool filter pressure is high, and what you can do to address the issue.

1. Dirty Filter

One of the most common reasons for high pool filter pressure is a dirty filter. Over time, the filter becomes clogged with dirt and debris, which restricts the flow of water through the filter. This restriction causes the pump to work harder to push water through the filter, resulting in an increase in pressure. If you notice that the pressure gauge on your pool filter is higher than normal, you should check the filter for any signs of dirt or debris.

2. Broken or Damaged Filter

In some cases, high pool filter pressure can be caused by a broken or damaged filter. If the filter is cracked or has a hole in it, it can cause water to leak out of the filter, reducing the flow of water through the filter. This reduction in flow can cause the pump to work harder to push water through the filter, resulting in high pressure. If you suspect that your filter is damaged, you should have a professional inspect it to determine if it needs to be repaired or replaced.

3. Clogged Skimmer Basket

Another possible cause of high pool filter pressure is a clogged skimmer basket. The skimmer basket is responsible for trapping leaves, debris, and other contaminants before they reach the filter. If the skimmer basket is clogged, it can restrict the flow of water through the filter, causing high pressure. To address this issue, you should clean the skimmer basket regularly to ensure that it is free of any debris or contaminants.

4. Improperly Sized Pump or Filter

If your pool filter pressure is consistently high, it could be due to an improperly sized pump or filter. If the pump is too small for your pool, it will have to work harder to circulate the water through the filter, resulting in high pressure. Similarly, if the filter is too small for your pool, it will not be able to keep up with the volume of water flowing through it, resulting in high pressure. If you suspect that your pump or filter is improperly sized, you should consult a professional to determine the appropriate size for your pool.

5. Algae Growth

Finally, high pool filter pressure can sometimes be caused by algae growth in the pool. Algae can clog the filter and restrict the flow of water, causing the pump to work harder and resulting in high pressure. To address this issue, you should regularly shock your pool to kill any algae, and ensure that your pool water chemistry is balanced to prevent further algae growth.

In conclusion, high pool filter pressure can be caused by a variety of factors, including a dirty filter, a broken or damaged filter, a clogged skimmer basket, an improperly sized pump or filter, and algae growth in the pool. By identifying the cause of high pressure, you can take the appropriate steps to address the issue and ensure that your pool water is clean and healthy. Remember to regularly inspect and clean your pool filter to prevent high pressure and maintain optimal pool performance.
