Why is Pool Filter Pressure Low?

As a pool owner, maintaining the cleanliness and hygiene of your pool is of utmost importance. Pool filters play a key role in the pool cleaning process by removing unwanted dirt, debris, and contaminants from the pool water. However, a common problem faced by several pool owners is low filter pressure, which can reduce the efficiency of the pool filters, preventing them from functioning effectively.

In this article, we'll explore why low pool filter pressure occurs, and how you can fix it to ensure your pool stays clean and healthy.

What Causes Low Pool Filter Pressure?

There can be several reasons why your pool filter pressure is low. Here are the most common ones:

1. Clogged Pool Filter

Over time, pool filters can become clogged with debris and dirt, which can restrict the flow of water through the filter, causing low filter pressure. Regular cleaning and maintenance of the filter is essential to prevent clogging and maintain optimal pressure.

2. Dirty Pump Basket

The pump basket plays an important role in preventing debris from entering the pool pump. However, if the basket is dirty and clogged, it can reduce the flow of water and cause low filter pressure.

3. Leaking Plumbing

Leaks in the plumbing connecting the pool filter and pump can cause low filter pressure. If you notice a leak, it's important to get it fixed as soon as possible to prevent further damage.

4. Air in the System

Air bubbles in the pool filter system can cause low pressure. This can occur when the pool skimmer basket is clogged, or when there's a problem with the pool pump's lid O-ring.

5. Wrong Pool Filter Size

Using a filter that's too small for your pool can cause low filter pressure. The filter size should be chosen based on the pool size and the gallons of water it holds.

How to Fix Low Pool Filter Pressure

Once you've identified the cause of low pool filter pressure, you can take the necessary steps to fix it. Here are some solutions:

1. Clean and Maintain Pool Filter

Regular cleaning and maintenance of the pool filter is crucial to prevent clogging and maintain optimal pressure. This includes backwashing, rinsing, and cleaning the filter cartridge.

2. Check and Clean Pump Basket

The pump basket should be checked and cleaned regularly to prevent clogging and ensure smooth water flow.

3. Repair Leaking Plumbing

If you notice a leak in the plumbing, it's important to get it fixed as soon as possible to prevent further damage.

4. Remove Air from the System

To remove air bubbles, try running the pool pump on "recirculate" mode for a few minutes. This will clear any air in the system.

5. Get the Right Pool Filter Size

Check with a pool professional to ensure you're using the right filter size for your pool.

Conclusion

Low pool filter pressure can cause your pool's filtration system to function poorly, leading to unclean and unsanitary water. By identifying the cause and taking the necessary steps to fix it, you can ensure your pool stays clean, healthy and enjoyable for years to come.
