Swimming pools are great places to cool off and enjoy during hot summer days. However, to keep the water clean and safe for swimmers, pools require a lot of maintenance. One of the most important tasks in keeping a pool clean is to properly backwash the filter. In this article, we will discuss how to backwash an inground pool filter.

Why Backwashing is Important

Submerged in water, the pool filter plays a crucial role in maintaining the pool's hygiene by filtering out impurities like dirt, debris, and other pollutants. However, over time, these impurities build up in the filter and reduce its ability to work correctly. This reduction in the filter's performance results in impaired water flow and dirty pool water.

Backwashing is the process of reversing the flow through the filter to purge the filter's impurities and restore its effectiveness. Performing this task is an essential aspect of maintaining the health of your pool's system.

When Should You Backwash?

There are a few tell-tale signs that your pool filter needs to be backwashed. The most obvious sign is a significant reduction in water flow coming from your filtration system. Other signs include increased water pressure on your filtering equipment and a cloudy appearance in your pool water.

What You Will Need

Before beginning the backwashing process, you will need a few essential items. These items include a pair of safety goggles, a pair of gloves, and a backwash hose. The hose should be long enough to reach a drain, garden bed, or similar drainage area. You can purchase a hose from a hardware or pool supply store.

Backwashing Steps

Once you have gathered all the necessary items, you can begin the backwashing process by following these simple steps:

Step 1: Turn off the pump

Before starting any work on your filtration system, turn off your pool's water pump. This action will help prevent the pump from damage and ensure your safety as you work on it.

Step 2: Understand your equipment

Familiarize yourself with the pool's filtration system and find the backwash valve. Different pool filters will have slightly different setups, so it is important to read your instruction manual carefully.

Step 3: Connect the backwash hose

Connect the backwash hose to the backwash valve on your pool pumping system. Ensure that the hose is securely attached before turning the valve handle to "backwash."

Step 4: Turn on the pump

Turn on the pump and allow it to run for a few minutes. During this time, you will see dirty water flowing out of the backwash hose. Wait until the water coming out of the hose becomes clear before moving on to the next step.

Step 5: Rinse the filter

Turn off the pump and change the backwash valve's position to "rinse." Turn on the pump to flush out any remaining impurities, then turn it back off.

Step 6: Turn the system back on

Return the backwash valve to its original position, turn on the pump, and let the filter load.

Conclusion

Backwashing your pool filter is an essential procedure for any pool owner to keep their pool water free of contaminants. When performed correctly, backwashing restores your filter's efficiency and extends its life. By following these simple steps, you can maintain your pool filter's health and keep your pool water crystal clear.
