How To Clean A DE Filter
A DE (diatomaceous earth) pool filter is an effective and popular method of filtering pool water. However, to maintain its efficiency, it needs to be cleaned regularly. A dirty DE pool filter can cause the pool water to become cloudy, and if left unattended, it can lead to other issues such as algae growth and the breakdown of pool equipment. In this article, we will discuss how to clean a DE pool filter to keep it functioning at its best.
Step 1: Turn off the pump and relieve the pressure
Before beginning the cleaning process, turn off the pool pump and relieve the pressure in the filter. This is done by turning the air release valve on the top of the filter. This step is essential to prevent any accidents and ensure the safety of the person cleaning the filter.
Step 2: Remove the filter element
The DE pool filter has a filter element that needs to be removed before cleaning. This is done by loosening the clamp or nut that secures the filter element in place. Be sure to follow the manufacturer’s instructions on how to remove the filter element to avoid damaging it.
Step 3: Inspect the filter element
Once the filter element has been removed, inspect it for any damage or tears. If the filter element is damaged, it may need to be replaced. It’s essential to replace damaged filter elements to maintain the filter’s efficiency and prevent any issues with pool water quality.
Step 4: Clean the filter element
To clean the filter element, it needs to be soaked in a solution of water and a DE filter cleaner. Follow the instructions on the DE filter cleaner for the appropriate ratio of water and cleaner. Typically, it’s recommended to use 1 lb of DE filter cleaner per 5 gallons of water.
Soak the filter element in the solution for at least 12 hours, but it’s recommended to soak it overnight. This will allow the cleaner to dissolve and loosen any debris that has accumulated on the filter element.
Step 5: Rinse the filter element
After soaking the filter element, it needs to be rinsed thoroughly with a garden hose. Start by spraying the outside of the filter element and then work your way to the inside. The goal is to remove all the debris and cleaner from the filter element.
Step 6: Inspect and replace o-rings
Inspect the o-rings on the filter element and the filter housing for any damage or wear. O-rings that are damaged or worn can cause leaks and reduce the efficiency of the filter. Replace any damaged or worn o-rings with new ones.
Step 7: Reassemble the filter
Once the filter element is clean and the o-rings have been replaced, it’s time to reassemble the filter. Follow the manufacturer’s instructions on how to properly secure the filter element in place. Be sure to tighten the clamp or nut securely to prevent any leaks.
Step 8: Add DE filter powder
Once the filter has been reassembled, it’s time to add DE filter powder. The amount of DE filter powder needed will depend on the size of the filter. Follow the manufacturer’s instructions on the appropriate amount of DE filter powder to add.
Slowly pour the DE filter powder into the skimmer while the pump is running. The powder will be drawn into the filter and coat the filter element.
Step 9: Check the pressure gauge
After adding the DE filter powder, it’s essential to check the pressure gauge. The pressure gauge measures the pressure in the filter and indicates when it’s time to clean the filter element again.
If the pressure gauge shows a pressure increase of 8-10 psi above the normal operating pressure, it’s time to clean the filter element again. It’s important to clean the filter element regularly to maintain the filter’s efficiency and prevent any issues with pool water quality.
Step 10: Maintain regular cleaning schedule
To keep the DE pool filter working efficiently, it’s important to maintain a regular cleaning schedule. The frequency of cleaning will depend on the size of the filter, the pool size, and the amount of debris that enters the pool. As a general rule, it’s recommended to clean the filter element at least twice a year, but it may need to be cleaned more frequently.
Regularly checking the pressure gauge can help determine when it’s time to clean the filter element. If the pressure gauge indicates a pressure increase of 8-10 psi above the normal operating pressure, it’s time to clean the filter element.
In addition to regular cleaning, it’s important to maintain the pool’s water chemistry. A well-balanced pool can reduce the amount of debris that enters the pool and can help extend the life of the filter element.
Conclusion
Cleaning a DE pool filter is an essential part of maintaining a clean and healthy pool. It’s important to follow the manufacturer’s instructions when cleaning the filter element to avoid damaging it. Regular cleaning of the filter element, as well as maintaining the pool’s water chemistry, can help extend the life of the filter and keep the pool water clean and clear.
If you are not comfortable cleaning the DE pool filter yourself, you can hire a pool professional to do it for you. A pool professional can also help you determine the appropriate cleaning schedule and provide advice on maintaining the pool’s water chemistry. By following these tips, you can ensure that your DE pool filter is functioning at its best and keep your pool water crystal clear all summer long.
