How to Backwash an Intex Pool Filter: A Comprehensive Guide

Introduction

Keeping your pool water clean and clear is important for maintaining a healthy swimming environment. One of the key components of any pool system is the filter, which helps to remove dirt, debris, and other impurities from the water. Over time, however, filters can become clogged, reducing their effectiveness and limiting their lifespan. Backwashing is a simple, but critical, process that helps to remove these contaminants from the filter and improve its performance. In this article, we'll provide a step-by-step guide on how to backwash an Intex pool filter, which is used in many above-ground pools.

Understanding Your Intex Pool Filter

Before we dive into the specifics of backwashing, it's important to have a basic understanding of your Intex pool filter. Intex filters come in different sizes and styles, but they all function in the same basic way. They use a filter cartridge made of a porous material, such as paper or polyester, which traps dirt and debris as the water flows through it. The filter cartridge is housed inside a plastic casing, which is connected to the pool pump and plumbing.

Why Backwashing is Important

Over time, the filter cartridge can become clogged with dirt and debris, reducing its ability to effectively filter the water. This can cause the water to become cloudy or even green, indicating the presence of algae or other harmful contaminants. Backwashing is a simple process that can help to remove these contaminants from the filter, reducing its workload and improving its efficiency. Regular backwashing can help to extend the life of your filter cartridge and keep your pool water clean and clear.

Step-by-Step Guide to Backwashing Your Intex Pool Filter

1. Turn off the pool pump: Before beginning the backwashing process, you'll need to turn off the pool pump to prevent water from flowing into the filter while you're cleaning it. This will allow the pressure inside the filter to drop to a safe level.

2. Locate the backwash valve: The backwash valve is typically located on the top or side of the filter casing. It will be labeled with the word "backwash" or a similar designation.

3. Attach the backwash hose: Connect one end of the backwash hose to the backwash valve and the other end to a safe location for the waste water to be discharged, such as a drainage ditch or sewer drain. Ensure that the hose is securely attached to prevent leaks.

4. Turn on the pump and backwash: With the backwash hose in place, turn the pool pump back on and set it to the "backwash" position. The water will flow backwards through the filter cartridge, dislodging dirt and debris and flushing it out through the backwash valve and hose.

5. Wait and rinse: Allow the backwash process to run for 2-3 minutes, or until the water flowing out of the backwash hose runs clear. Then, turn the pump off and switch it to the "rinse" position. This will flush out any remaining debris and prevent it from returning to the pool. Run the rinse cycle for 1-2 minutes.

6. Shut down and reset: After completing the backwash and rinse cycles, turn off the pump and reset the filter valve to the "filter" position. Disconnect the backwash hose and store it away until the next cleaning.

Conclusion

While it may seem like a small task, backwashing your Intex pool filter is a critical part of maintaining a healthy swimming environment. By following these simple steps, you can keep your filter working at peak performance and ensure that your pool water remains clear and clean. Remember to backwash your filter regularly, especially during times of heavy usage or after a storm, to keep your pool in top shape all season long.
