how to clean sta rite pool filter

Author: PoolKing - Pool Sand Filter Manufacturers

Keeping your pool clean isn't just about maintaining the water chemistry. It's also important to have a clean and functioning pool filter. The Sta-Rite pool filter is a popular choice for many pool owners because of its durability and efficient filtration process. However, even the best pool filter needs to be cleaned regularly to remove debris and maintain proper water flow. In this article, we'll go over how to clean your Sta-Rite pool filter so it can continue to keep your pool sparkling clean all season long.

1. Understanding the Sta-Rite Pool Filter

Before you can properly clean your Sta-Rite pool filter, it's important to understand its parts and how it functions. The Sta-Rite pool filter is a high-rate sand filtration system that uses a special type of sand called AquaQuartz. This sand is designed to trap debris and particles as small as 20 microns. The filter includes a tank, a diffuser, a standpipe, laterals, and a nozzle.

2. Turn Off the Pump and Drain the Water

Before you can begin cleaning the pool filter, you need to turn off the pool pump to ensure no water is flowing into the filter. Next, drain any standing water in the filter by opening the air relief valve. This will release trapped air and water pressure.

3. Remove the Filter Tank Lid

The filter tank lid is located on top of the tank and can be removed by loosening the clamps or bolts that secure it in place. Once the lid is removed, you'll be able to access the filter's sand and other components.

4. Inspect the Sand

Inspect the sand to see if it needs to be replaced. The sand in the filter should be replaced every 3-5 years, depending on use and pool conditions. If the sand is worn down or caked in debris, it's time to replace it.

5. Clean the Sand and Laterals

If the sand doesn't need to be replaced, you'll want to clean it and the laterals. Using a garden hose, rinse the sand and laterals thoroughly to remove any debris or buildup. You can also use a pool filter cleaner to help remove any stubborn debris. Be sure to clean each lateral individually to ensure they are all clear and functioning properly.

6. Reassemble the Filter

Once everything is clean and in good condition, it's time to reassemble the filter. Replace the standpipe and laterals into the bottom of the tank and carefully pour in the new sand. Be sure to fill the tank to the manufacturer's recommended level.

7. Restart the Pump

Finally, it's time to restart the pool pump and allow the filter to run for several minutes before adding any chemicals or chlorine. This will allow the filter to circulate clean water throughout the system and ensure everything is functioning properly.

In conclusion, cleaning your Sta-Rite pool filter is essential for keeping your pool clean and maintaining proper water flow. By following these simple steps, you can easily clean your filter and keep your pool sparkling all season long. If you have any questions or concerns, be sure to consult the manufacturer's instructions or contact a pool professional for assistance.

----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.
After about 5~10days ,or when the reading of the pressure gauge on the pump side of the filter has increased by about 0.2bars since the last backwash , backwash the filter as follows:
1. Stop the pump
2.Close the valves on the suction and return lines.
3.Open the cover of the pump and empty the filter gasket .
4.Refit the cover
5.Open the valve to the drain outlet
6.Turn the lever to BACKWASH
7. Open the valves to the suction and return lines.
8.Start the pump .Rinse the filter for about 1 to 2 minutes until the water in the sight glass is clear .
NOTE : Any electric heater must be off .
9. Stop the pump
10. Turn the lever to RINSE , start the pump and rinse for about 15~30 seconds. Stop the pump and turn the lever to FILTER . This is the normal operating position .
11. Close the drain outlet valve and start the pump . Switch on the electric heater if any .
