how to add sand to pool filter

Author: Poolking - Swimming Pool Equipment Manufacturer

If you have recently purchased a pool filter or have been using one for a while, you may be aware that one of the essential maintenance activities is adding sand to the filter. Sand filters are a popular choice among pool owners, as they effectively remove debris and unwanted particles from the water. However, over time, the sand inside the filter wears out and needs to be replaced for the filter to work efficiently. In this article, we will guide you through the steps of adding sand to your pool filter to keep your pool water crystal clear.

Why Do You Need to Add Sand to Pool Filter?

Pool filters continuously pump water through the sand to remove dirt, debris, and other contaminants. As water flows through the filter, the sand's particles trap the dirt, which separates from the water and gets deposited in the filter. Over time, the sand's sharp edges dull out, and the particles become smoother, reducing the filter's efficiency. To ensure that your filter continues to function optimally, you need to add fresh sand regularly.

How Often to Add Sand to Pool Filter?

The frequency at which you need to add sand to your pool filter depends on several factors. If you use your pool heavily or have an unusually high level of contaminants in the water, you may need to change the sand more often. In general, most pool owners need to add sand every three to five years.

Buy the Right Kind of Sand

Not every kind of sand is suitable for use in pool filters. You must buy a specialized pool filter sand that is designed to trap dirt, debris, and other particles efficiently. Do not use sand that you would use for making concrete, as it can damage your filter or cause blockages that could lead to expensive repairs.

Choose the Right Amount of Sand

Before adding sand to your pool filter, ensure you know the correct amount you need. Adding too much sand can decrease the filter's efficiency, while adding too little can cause damage to the impeller or pump motor. Consult the manufacturer's instructions or contact a professional to determine the correct amount of sand needed for your filter.

Preparing the Pool Filter

Before adding new sand, it's essential to clean the pool filter thoroughly. This process involves backwashing the filter and clearing out any debris or dirt that might have accumulated inside. After backwashing, let the filter run on the rinse setting for at least 30 seconds to clean out any leftover debris or dirt.

Add Sand to Pool Filter

Once the pool filter is clean, it's time to add the sand. Start by adding a few inches of sand to the bottom of the filter tank and level it out. Next, insert the filter's center pipe and ensure it's secure. Then, slowly pour the rest of the sand into the filter, ensuring you do not pack it too tightly. Stop pouring sand when you reach the required depth, as overfilling can cause damage to the filter.

Replacing the Multiport Valve or Lateral Assembly

After adding sand, you must replace the multiport valve or lateral assembly, depending on the type of filter you have. The multiport valve directs water through the filter in the right way, while the lateral assembly distributes clean water back to the pool. Make sure you follow the correct replacement procedure to avoid damaging the filter.

In conclusion, adding sand to your pool filter is an essential maintenance step that ensures your pool stays clean and healthy for swimming. Follow these easy steps to safely and effectively add sand to your pool filter, and enjoy clear, sparkling pool water all summer long.

----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.
