If you own a pool, you know how important it is to keep it clean and maintained. Part of that maintenance includes ensuring your pool filter is working properly. If you notice your pool filter isn't functioning properly, it could be due to air being trapped inside. But don't worry, getting air out of your pool filter isn't as difficult as you may think. In this article, we'll break down how to get air out of pool filters and provide some tips to make sure it doesn't happen again.

Understanding Your Pool Filter

Before we dive into how to get air out of your pool filter, it's important to understand the different types of pool filters and how they work. Generally, there are three types of pool filters: sand filters, cartridge filters, and DE (diatomaceous earth) filters.

Sand filters: These pool filters use sand as the filtering medium. Water enters the filter, passes through the sand, and then returns to the pool.

Cartridge filters: Cartridge filters use paper or fabric cartridges to remove dirt and debris from the pool water. Water enters the filter, passes through the cartridge, and then returns to the pool.

DE filters: These filters use a fine white powder called diatomaceous earth to filter the water. The powder is poured into a tank called a filter and coats a thin layer on a grid within the filter. Water passes through the grid, and the DE powder removes any dirt and debris.

Why Air Gets Trapped in Pool Filters

Air can become trapped in pool filters for a few different reasons. One of the most common reasons is because of a low water level. If the water level in your pool drops below the skimmer, air can be drawn into the system. Another reason is due to a faulty or damaged O-ring. The O-ring is a small rubber ring that creates a seal around the lid of your pool filter. If this ring is damaged or worn, air can enter the system.

5 Steps to Get Air Out of Your Pool Filter

Now that you understand why air becomes trapped in pool filters let's dive into how to get rid of it.

Step 1: Turn off the pump

The first step is to turn off the pump. You don't want to attempt to remove air from the pool filter if it's still running.

Step 2: Check water levels

Next, check the water level in your pool. If it's below the skimmer, you'll need to add water before continuing.

Step 3: Locate the air release valve

The air release valve releases any trapped air in your pool filter. You'll need to locate this valve- it's usually located at the top of the filter tank.

Step 4: Open the air release valve

Using the valve's lever, open the air release valve. Water will begin to come out of the valve. You should see air bubbles coming out with the water.

Step 5: Close the valve

Once you see only water coming out of the valve, it's time to close it. This means the air has successfully been removed from your pool filter.

Tips to Avoid Air in Your Pool Filter

While getting air out of your pool filter is a quick and easy fix, it's important to take steps to ensure it doesn't happen again. Here are a few tips:

- Keep your water levels above the skimmer.

- Check and replace O-rings if they become worn or damaged.

- Schedule regular maintenance on your pool filter to ensure it's working correctly.

- Don't overbackwash your filter. This can cause air to enter your system.

In conclusion, getting air out of your pool filter is a simple process that can be done quickly if you follow these steps. But don't forget to take precautions to ensure it doesn't happen again. Proper maintenance and care of your pool filter can save you time and money in the long run.
