How to Prime an Inground Pool Sand Filter

Learn How to Prime Your Inground Pool Sand Filter with These Simple Steps

Priming an inground pool sand filter is an important step in maintaining the cleanliness and clarity of your pool water. It involves filling the filter with water and removing any air pockets to ensure that the filter is functioning properly. Here is a step-by-step guide on how to prime an inground pool sand filter:

Step 1: Turn off the pool pump

Before priming the filter, make sure the pool pump is turned off. This will prevent any debris or water from entering the filter while priming.

Step 2: Locate the filter's air relief valve

The air relief valve is usually located on top of the filter tank. It is a small valve that allows air to escape from the filter during the priming process.

Step 3: Open the air relief valve

Turn the air relief valve counterclockwise to open it. This will allow any air trapped in the filter to escape.

Step 4: Fill the filter with water

Using a garden hose, slowly fill the filter tank with water until it is about halfway full. Be sure to fill the tank slowly to prevent any air pockets from forming.

Step 5: Close the air relief valve

Once the filter is halfway full, close the air relief valve by turning it clockwise. This will prevent any water from escaping the filter during the rest of the priming process.

Step 6: Turn on the pool pump

Turn on the pool pump and let it run for several minutes. As the water circulates through the filter, it will push out any remaining air pockets.

Step 7: Check the pressure gauge

After a few minutes of running the pump, check the pressure gauge on the filter. The pressure should be at the manufacturer's recommended level. If the pressure is too high or too low, adjust the pump accordingly.

Step 8: Finish filling the filter

Once the filter is primed and the pressure is at the proper level, finish filling the filter tank with water until it reaches the top.

Step 9: Close the pump's discharge valve

Finally, close the pump's discharge valve to prevent water from escaping the filter. Your inground pool sand filter is now primed and ready to use!

In conclusion, priming an inground pool sand filter is a simple process that can help keep your pool water clean and clear. By following these steps, you can ensure that your filter is functioning properly and your pool is ready for swimming season.
