How to Backwash a Small Pool Filter

If you have a small pool in your backyard and are wondering how to backwash the pool filter, don't worry. Backwashing a small pool filter is pretty easy, and you don't need professional help to do so. By following a few simple steps, you can backwash your pool filter in no time. Here's how.

1. Understanding the pool filter

Before you start with the backwashing process, it's essential to understand how the pool filter works. The pool filter is responsible for removing dirt and debris from the water, leaving it clean and clear. The filter does this by forcing the water through a porous medium, such as sand or diatomaceous earth, that traps the dirt particles. Over time, the filter media can become clogged with dirt, which reduces the effectiveness of the filter. This is where backwashing comes in.

2. Switch off the pool pump

Before you begin backwashing, switch off the pool pump to prevent any backflow. This step is crucial to prevent any accidents from happening. If the pump is left on while backwashing, dirty water can flow back into the pool, defeating the purpose of backwashing the filter.

3. Locate the backwash valve

The next step is to locate the backwash valve, which is typically located on the side of the pool filter. The valve may be labeled or colored differently, depending on the make and model of your filter. Once you locate the valve, turn it to the "backwash" setting.

4. Connect the backwash hose

After turning the backwash valve to the "backwash" setting, connect the backwash hose to the filter's waste port. The waste port is usually located at the bottom of the filter tank, and it lets the dirty water wash out of the filter.

5. Turn on the pump and backwash

With the backwash hose connected, turn on the pool pump and observe the water flowing out of the hose. The water will appear cloudy at first, but as the backwash process continues, the water will clear up. The backwashing process should continue until the water coming out of the hose is clear and clean.

6. Rinse the filter

Once the water coming out of the backwash hose is clear, you can switch the valve to the "rinse" setting for about 30 seconds. This step helps to remove any remaining debris from the filter.

7. Return the valve to the "filter" setting

After rinsing the filter, return the valve to the "filter" setting and turn on the pool pump. This step will allow the clean water to flow back into the pool.

In conclusion, backwashing a pool filter is a straightforward process that can be done in a matter of minutes. By following these simple steps, you can ensure that your pool stays clean and clear all season long. Remember to backwash your filter regularly to maintain its effectiveness and prevent any damage.
