What to Do After Changing Sand in Pool Filter

Having a pool in your home is a great way to relax and cool off during the hot summer months, but maintaining it can be quite a chore. Among the many important components in your pool system, the filtration system is one of the most vital. The pool filter helps to keep your pool clean and free from harmful bacteria and debris. Changing the sand in your pool filter is one of the routine maintenance tasks that you must do to ensure that your pool stays in excellent condition.

If you have recently changed the sand in your pool filter, you may be wondering what to do next. In this article, we will discuss some essential steps that you should take after changing the sand in your pool filter to ensure that your pool remains crystal clear and healthy for you and your family.

Step 1: Backwash and Rinse the Filter

After replacing the sand in your pool filter, you must backwash it. Backwashing the filter involves reversing the flow of water through the filter to flush out any debris and contaminants that may have accumulated in the sand. To backwash the filter, simply turn the valve to the backwash setting and let the water run until the water coming out of the waste pipe is clear.

After backwashing, you need to rinse the filter. This step helps to ensure that any remaining debris and contaminants are removed from the filter. To rinse the filter, turn the valve to the rinse setting and let the water run through the filter for a few minutes.

Step 2: Add Filter Media

Once you have backwashed and rinsed the filter, you can add the new sand or other filter media that you have chosen. Be sure to follow the manufacturer's instructions for your particular filter to ensure that you add the correct amount of filter media.

Step 3: Test the Water Balance

After you have changed the sand in your pool filter, you should test the water balance. Testing the water will help you to determine if you need to make any adjustments to the pH, alkalinity, or chlorine levels in your pool. By keeping the water in the correct balance, you can ensure that it remains sparkling clean and safe for swimming.

Step 4: Run the Filter System

Once you have tested the water balance and made any necessary adjustments, it's time to run the filter system. Turn the pool pump on and run it for a few hours to ensure that the water is circulating correctly. You can also use this time to check for any leaks or other issues with the filter or pump system.

Step 5: Monitor the Filter System

After you have run the filter system for a few hours, you should monitor it closely. Check the pressure gauge on the filter to ensure that it is not too high or too low. If the pressure is too high, you may need to backwash the filter again to remove any debris that may be causing the blockage.

----It is best to replace the silica sand of sand filters every 1-2 years for the following reasons:
a During backwashing, the filtration bed volume will expand upwards by 1.2 to 1.3 times. The water flow will drive the filtration layer to flow up and down, causing the filtration material particles to collide with each other. Backwash will let the small sand evacuate.
b.Some silica sands will be welded when the acid and alkali are changed due to insufficient purity;
Therefore, the longer the time, the worse the filtering effect of the sand tank. Since backwashing will consume and take away some sand, we need to replace the sand in the sand tank within the specified period.
