Swimming pools provide great opportunities for recreation, relaxation, and exercise. However, to maintain its cleanliness, you need to have a properly functioning pool filter. The Hayward pool filter is a reliable option for keeping your pool crystal clear. Yet, how often do you need to change the sand in your Hayward pool filter? This article provides you with the answer.

What is a Hayward pool filter and how does it work?

Before diving into the topic of how often to change sand in a Hayward pool filter, let's first understand what this type of filter is and how it works.

There are three types of Hayward pool filters: sand filters, cartridge filters, and Diatomaceous Earth filters. Each type of filter is designed to remove impurities and debris from your pool water.

A sand filter, the most common of the three types, is made up of a tank filled with sand, which captures impurities as the water passes through. The water flows into the top of the filter, passes through the sand, and emerges as clean water through the return line.

How often should you change the sand in a Hayward pool filter?

When sand filters are installed, the sand bed is filled up to 2/3rd the volume of the tank, leaving enough space for the water to flow freely. The sand in your Hayward pool filter should ideally be changed every five years. This doesn't mean that you have to wait for five years before changing the sand. The sand bed should also be cleaned at least once a year to keep the filter working efficiently.

Why should you clean your Hayward pool sand filter?

Over time, the sand particles in your filter become clogged with debris, making it difficult for water to pass through and reducing the efficiency of the filtration system. This leads to increased strain on the motor, which can cause the pump to fail prematurely. Dirty sand can also result in an unhygienic pool, as it won't be able to catch and eliminate contaminants effectively.

How to clean your Hayward pool filter?

Cleaning your pool sand filter is a straightforward process that you can do yourself. All you need to do is to turn off the pump and filter system, remove the drain cap, and let the water drain out. Then, you can remove the filter head and carefully remove the sand bed. Rinse the sand bed with a hose, and reassemble the filter. Finally, add fresh sand to the filter, and the process is complete.

Benefits of changing your Hayward pool sand filter

Regularly changing the sand in your Hayward pool filter has numerous benefits, including:

1. Improved efficiency – Clean sand filters work more effectively to remove impurities, debris, and algae, resulting in a sparkling clean pool.

2. Cost-effective – Not only will changing the sand improve the performance of your pool filter, it can also save you money in the long run by avoiding costly repairs or the need for a new pump.

3. Better health – A clean pool is essential for the health and wellbeing of your family and friends. Changing your sand filter can help ensure that your pool stays clear and hygienic.


In conclusion, changing the sand in your Hayward pool filter is a critical part of maintaining a clean and healthy swimming pool. Ideally, you want to change the sand every five years, but cleaning the sand bed annually is also essential to keep your filter working efficiently. By following these guidelines, you will enjoy a sparkling clean pool that's sure to impress all those who swim in it.
