What Does Backwash Pool Filter Mean?

When you own a swimming pool, it's crucial to ensure that the pool water is clean and healthy for you and your family. Whether you enjoy swimming laps or lounging by the poolside, dirty pool water can ruin your experience. One of the essential parts of a pool is the filter, which is responsible for removing debris, dirt, and other contaminants from the water. In this article, we'll discuss what backwash pool filter means and why it's essential to keep your pool filter working correctly.

What Is a Pool Filter and How Does It Work?

Before we discuss backwashing, let's understand what a pool filter is and how it works. A pool filter is a device that removes impurities from the pool water by pushing it through some form of filtration material. The most common types of pool filters are sand, cartridge, and diatomaceous earth (DE) filters. Sand filters are the most basic of the three, and they work by passing water through a bed of sand. Cartridge filters use a pleated material, while DE filters use a powder-like substance that coats a grid within the filter.

Why Do You Need to Backwash Your Pool Filter?

Over time, the pool filter will become clogged with debris, dirt, and other contaminants. This buildup can reduce the efficiency of the filter and, if left untreated, can cause damage to the filter mechanism or result in the pump becoming overworked. Backwashing is a process that cleans out this buildup by reversing the flow of water through the filter, flushing out the debris and contaminants and sending them out to waste.

When to Backwash Your Pool Filter?

Backwashing frequency will depend on the pool's size, usage, and pool filter type. As a general rule, you should backwash your pool filter when the pressure gauge indicates a rise of 8-10 psi above your filter's clean pressure. If you're uncertain about how often to backwash your filter, you can check with a certified pool professional.

How to Backwash Your Pool Filter?

To backwash your pool filter, follow these steps:

1. Turn off the pump

2. Set the multiport valve to "backwash"

3. Turn on the pump

4. Run the pump for 2-3 minutes or until the wastewater is clear

5. Turn off the pump

6. Set the multiport valve to "rinse"

7. Turn on the pump

8. Run the pump for 15-30 seconds or until the wastewater is clear

9. Turn off the pump

10. Set the multiport valve back to "filter."

Conclusion

In conclusion, having a working pool filter is essential for maintaining clean and healthy swimming pool water. Backwashing your pool filter is an essential maintenance step to ensure your filter is working correctly and prolong its lifespan. Knowing when to backwash and how to do it can help keep your pool in top condition and provide you with a better swimming experience. Remember to always turn off the pump and follow the proper steps when backwashing your pool filter.
