How Do You Clean a Hayward Pool Filter?

Swimming pools are a great source of fun and relaxation during summertime. However, maintaining and cleaning them can be a daunting task. To keep your pool clean and hygienic, a pool filter is essential. The Hayward pool filter is one of the most popular and effective pool filters in the market. But if you're new to pool cleaning or have recently acquired a pool, you might be wondering how do you clean a hayward pool filter. In this article, we'll guide you through the step-by-step process of cleaning your Hayward pool filter to ensure that your pool remains clean and safe for swimming.

Subheading 1: Understand the type of Hayward pool filter you have

Before you start cleaning your pool filter, you need to understand the type of Hayward pool filter you have. Hayward offers three types of pool filters: sand filters, diatomaceous earth (DE) filters, and cartridge filters. Each type of filter requires a different cleaning approach. It's important to know which type of filter you have to avoid damaging the filter or wasting time and effort.

Subheading 2: Turn off the pool pump and relieve pressure

Safety is a critical aspect when cleaning the Hayward pool filter. Ensure that the pool pump is turned off before you begin cleaning the filter. You should also relieve the pressure in the filter by turning the valve to the "backwash" position to flush out any debris and allow air to enter the system.

Subheading 3: Disassemble the Hayward pool filter

After turning off the pool pump and relieving the pressure, it's time to disassemble the filter. This step involves opening and removing the filter parts, such as the filter head, laterals, or cartridges. You should also pay attention to the location of each removed part to simplify the reassembly process.

Subheading 4: Clean the Hayward pool filter

Once you've disassembled the filter, it's time to deep clean it. The cleaning process also depends on the type of Hayward pool filter you have. For sand filters, you need to backwash and rinse the sand bed thoroughly. On the other hand, DE filters require you to remove the filter grids and hose them off individually. Cartridge filters need to be soaked in a filter cleaner solution to remove trapped dirt and debris. It's crucial to follow the manufacturer's instructions when cleaning the filter and to use the recommended cleaning solutions or methods. Using stringent, abrasive cleaning solutions can damage or reduce the effectiveness of the filter.

Subheading 5: Reassemble the Hayward pool filter and turn on the pump

Once you've completed cleaning the filter parts and components, it's time to reassemble the filter. Ensure that each component fits well and adheres to the manufacturer's instructions. The recommended order of reassembling the filter parts is reversed to the disassembly process. Turn on the pool pump and monitor it to ensure there are no leaks or damages.


Your Hayward pool filter is the key to keeping your pool clean and hygienic. Cleaning it is a routine task that you need to master to ensure its longevity and effectiveness. Understanding the filter types, disassembling, cleaning, and reassembling are vital steps that must be followed to clean your Hayward pool filter. Stick to the recommended methods and safety guidelines to ensure that your pool remains safe for swimming.
