What Is Backwash Setting on Pool Filter?

When it comes to pool maintenance, one of the essential aspects is cleaning the filters. Filters remove debris, dirt and other contaminants from your pool water, keeping it clear and healthy. One of the most effective ways to clean the filter is by using the backwash setting. But what exactly is backwashing and why is it important? In this article, we will discuss everything you need to know about the backwash setting on a pool filter.

1. Understanding the Function of Pool Filters:

Before diving into backwashing, it's crucial to understand how a pool filter works. The pool water passes through the filter, and the debris gets trapped in the filter media, commonly sand, diatomaceous earth or cartridge. Over time, this debris clogs the filter media, reducing its efficacy.

2. What Is Backwash Setting on Pool Filter?

Backwashing is a critical cleaning process for all types of pool filters. The backwash setting is useful for reversing the flow of water through the filter to expel dirty water from the pool filter. This effectively cleanses the filter in preparation for another cycle of filtration. During backwashing, the filtered water runs out and dirty water from the backwash line enters the pool.

3. When to Backwash Pool Filter?

It's recommended to backwash the pool filter regularly to maintain healthy pool water. A general rule of thumb is to backwash the filter when the pressure gauge located on the filter indicates a rise in pressure (usually every 4-6 weeks). A dirty filter restricts the water flow; therefore, it increases the pressure in your filter system.

4. How to Backwash Pool Filter?

To backwash your pool filter, you will need to switch the filter valve to the backwash setting, switch off the pump and wait a few minutes. Then, turn on the pump and let it run for about two minutes or until the water runs clear. Now, switch the valve position to rinse, turn on the pump, and let it run for one minute to flush out the remaining dirt.

5. Maintenance Tips:

While backwashing is an excellent technique for cleaning the pool filter, regular professional maintenance is also recommended. Experts recommend getting a full system check every six months to ensure your pool filter is functioning correctly. Consistent maintenance guarantees you obtain the best performance from your pool filter, and your pool remains healthy and crystal clear.

In conclusion, backwashing is a crucial technique for every pool owner to be aware of regularly. It is simple to perform and can help you maintain clean, healthy pool water for years to come. Keep in mind that proper pool maintenance does not stop at backwashing. Additional routine maintenance is required to keep your pool in optimal condition. If you are unsure about the proper maintenance required for your pool filter, consult with a pool maintenance professional.
