How to Change Swimming Pool Filter Sand

Your swimming pool filter plays an important role in keeping your pool clean and safe to swim in. Over time, the sand in your filter can become clogged with debris and particles, reducing its effectiveness. It's important to know how to change your swimming pool filter sand so that you can maintain your pool's clarity and cleanliness. In this article, we will provide a step-by-step guide on how to change your swimming pool filter sand.

Before you Begin

Before starting the process of changing your swimming pool filter sand, you need to gather all the necessary equipment. You will need the following items:

- A new bag of filter sand

- A Phillips head screwdriver

- A pair of pliers

- A garden hose

- A bucket

- Duct tape

Step 1: Turn off your pool equipment

The first step in changing your swimming pool filter sand is to turn off your pool equipment. This includes turning off the pump, filter, and any other related equipment. Make sure that you also turn off the power to any electrical components that are connected to the filter.

Step 2: Remove the Filter Tank Cover

Using a Phillips head screwdriver, remove the screws that are holding the filter tank cover in place. Once the screws are removed, carefully lift off the cover and set it aside.

Step 3: Remove the Sand

Next, you will need to remove the filter sand from the tank. To do this, you will need to use a pair of pliers to remove the old lateral assembly. Be careful not to damage the laterals as they will need to be reused.

Once you have removed the lateral assembly, use a bucket to scoop out the old sand into a trash bag. You can also use a shop vac to remove the sand from the tank.

Step 4: Clean the Filter Tank

After you have removed all the filter sand from the tank, use a garden hose to wash out the inside of the tank. Make sure you rinse the tank thoroughly to remove any leftover sand or debris.

Step 5: Replace the Laterals

Once the tank is cleaned, you will need to replace the laterals. Make sure that the laterals are positioned correctly and that they are securely in place.

Step 6: Add New Filter Sand

Now that the laterals are in place, you can add the new filter sand to the tank. Be sure to follow the manufacturer's instructions to ensure that you have added the correct amount of sand.

Step 7: Reattach the Filter Tank Cover

Once the new sand is in place, you can reattach the filter tank cover. Use the screws you removed earlier to secure the cover in place.

Step 8: Start Up Your Pool Equipment

Finally, you can start up your pool equipment. Turn on the pump, filter, and any other related equipment. Make sure that you also turn on the power to any electrical components that are connected to the filter.

After your pool equipment is up and running, let it run for a few minutes to make sure that everything is working properly. Check the pressure gauge on your filter to make sure that it is at the correct level.

Conclusion

Changing your swimming pool filter sand is an important part of maintaining a clean and safe pool. By following these step-by-step instructions, you can easily change the filter sand in your swimming pool filter. Remember to always follow the manufacturer's instructions, and if you are unsure about anything, don't hesitate to contact a professional pool service technician.

----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.
----Yes, they can. Silica sand is mainly used for filtration, while activated carbon is mainly used for adsorption. Silica sand is effective for higher water quality requirements. When use them together, silica sand should be placed on the bottom layer, and then activated carbon should be filled on the sand, but the cost of using two media is much higher.
