How to Use Hayward Pool Filter: A Comprehensive Guide for Pool Owners

If you're the proud owner of a pool, then you're probably aware of the importance of having a reliable pool filter. It's the key to keeping your pool water clear, clean, and free of debris. However, you might not know how to use your Hayward pool filter properly. Don't worry; this article will guide you through the process, step-by-step. Read on to find out more.

Understanding the Hayward Pool Filter

Before we go any further, it's essential to understand what a pool filter does. Simply put, a pool filter removes dirt, debris, and other contaminants from your pool water. There are three types of pool filters, sand, cartridge, and diatomaceous earth (DE). The Hayward pool filter is a D.E filter, which stands for diatomaceous earth.

The Hayward D.E filter works by using a fine layer of diatomaceous earth powder that captures tiny particles as small as five microns. The filter element is coated with D.E powder, and water is forced through the powder, which traps the contaminants. The water then passes through the filter and back into the pool, leaving you with crystal clear water.

How to Use Your Hayward Pool Filter

Now that you understand the basics of how a pool filter works let's dive into how you can use your Hayward pool filter to keep your pool water sparkling clean.

1. Prepare the Hayward Filter

Before using your Hayward pool filter, you need to prepare it. Firstly, turn off the pool pump and relieve pressure in the filter by turning the air bleeder knob counterclockwise. Open the drain plug and remove any excess water from the filter tank. Check the filter elements and clean or replace them if needed. Finally, add the recommended amount of D.E powder to the filter.

2. Backwash the Filter

Backwashing is the process of cleaning the filter by reversing the water flow. You need to backwash your Hayward pool filter when the filter pressure gauge reads ten pounds more than the clean pressure. The backwash process varies with different models. Typically it involves turning off the pump, turning the valve handle to the backwash position, turning the pump back on, and letting it run for two to three minutes. You should see dirty water flowing out of the drain. Once it turns clear, turn off the pump, move the valve handle to the rinse position, and start the pump again, letting it run for 30 seconds.

3. Add D.E Powder

After backwashing, it's time to add D.E powder to your Hayward pool filter. You can do this through the skimmer or the filter's dedicated D.E feeder. Always follow the manufacturer's recommended D.E powder amount.

4. Check the Filter Pressure

Check the filter pressure gauge periodically to ensure it is at the correct level. If the pressure is too high, it's time to backwash the filter again. If the pressure is too low, add more D.E powder.

5. Clean the Hayward Filter

It's essential to clean your Hayward pool filter regularly to ensure optimal performance. You should do this at least twice each year, more frequently if you have heavy pool use or a lot of debris in your pool. To clean the filter, turn off the pump, relieve the pressure, remove the filter element, and clean it with a hose. You can also soak it in a solution of filter cleaner to remove any stubborn stains.


In conclusion, using a Hayward pool filter is essential for maintaining your pool water and ensuring it's always crystal clear. By following our step-by-step guide, you can easily maintain and care for your Hayward pool filter. Make sure to add D.E powder, backwash regularly, check the filter pressure, and clean the filter at least twice a year. With proper maintenance and care, your Hayward pool filter will keep your pool water sparkling clean and safe for swimming.
