When to Use Backwash on Pool Filter

Keeping your pool clean and sparkling is one of the essential tasks you need to do for your pool maintenance. As a pool owner, you need to make sure that the water is clear and free of debris, so you and your family can enjoy swimming in it. One of the ways to ensure that your pool is clean is by using a pool filter. A pool filter is an essential component of your swimming pool, and it helps to remove dirt, debris, and other contaminants from the water. However, over time, the filter becomes dirty and clogged, and the water flow slows down. This is where backwashing comes in. In this article, we will discuss when to use backwash on a pool filter, how to do it, and some other essential tips.

What is Backwashing?

Backwashing is the process of cleaning the pool filter by reversing the flow of water through it. When you backwash, you force water through the filter in the opposite direction, which dislodges and flushes out the dirt, debris, and other contaminants. The clogged water then drains out through the waste line of the pool, leaving you with a clean filter ready for use. Backwashing is an effective way of maintaining your pool filter and keeping the water crystal clear.

When to use Backwash on a Pool Filter

Knowing when to backwash your pool filter is essential to maintaining the cleanliness and hygiene of your pool. Typically, you should backwash your pool filter when the pressure gauge on your filter tank reads eight to ten pounds higher than the normal operating pressure. The pressure gauge is located on the filter's valve, and it measures the water pressure inside the filter. When the pressure gets too high, it means that the filter is clogged, and it's time to backwash. If you don't backwash when the pressure is high, the filter will not work correctly, and the water will not be adequately filtered, leading to cloudy or dirty water.

How to Backwash a Pool Filter

Backwashing your pool filter is a simple process that you can do yourself, without the help of a professional. Here are the steps to follow:

Step 1: Turn off the pump

Before you start the backwashing process, you need to turn off the pool pump. This prevents any damage or injury that may occur during the process.

Step 2: Turn the filter valve to backwash position

The filter valve has different positions, including filter, rinse, backwash, waste, closed, and recirculate. To backwash, turn the valve to the backwash position.

Step 3: Turn on the pump

After turning the valve to the backwash position, turn on the pump and let it run for about two minutes, or until the water in the sight glass becomes clear.

Step 4: Turn off the pump

Once the water in the sight glass is clear, turn off the pump and turn the valve to the rinse position.

Step 5: Turn on the pump again

After turning the valve to the rinse position, turn on the pump again and let it run for about a minute.

Step 6: Turn off the pump

Once the minute is up, turn off the pump and turn the valve back to the filter position.

Step 7: Turn on the pump

Finally, turn on the pump and let it run for a few minutes to ensure that the water flow is back to normal.

Other Essential Backwash Tips

Here are some other essential tips to keep in mind when backwashing your pool filter:

1. Backwash at least once a week, or more if necessary, depending on pool usage and weather conditions.

2. Always rinse your filter after backwashing to ensure that all the contaminants are flushed out.

3. Check the pressure gauge on a regular basis to ensure that the pressure is not too high or too low.

4. Replace your pool filter cartridge or sand every three to five years, depending on usage.

Conclusion

Using backwash on your pool filter is an important part of maintaining a clean and hygienic swimming pool. Knowing when to backwash and how to do it is crucial to ensuring that your pool filter functions properly, and the water is crystal clear. Remember to backwash regularly, rinse your filter after backwashing, and check your pressure gauge regularly. By following these tips, you can enjoy your pool and create lasting memories with your family and friends.
