How to Start a Sand Pool Filter

If you own a pool, you know the importance of keeping it clean and well-maintained. Part of that maintenance is making sure your sand pool filter is operating properly. Here is a step-by-step guide on how to start a sand pool filter so you can keep your pool clean and clear all summer long.

Step 1: Turn Off Your Pool Pump

Before your start your sand pool filter, it is important to turn off your pool pump. This will prevent any water from flowing through the system and potentially causing damage.

Step 2: Locate Your Multiport Valve

The multiport valve is the heart of your sand pool filter system. It is typically located near the pump and filter unit. Once you locate the multiport valve, make sure it is in the “filter” position. This is the default position for most sand pool filters.

Step 3: Open Your Backwash Valve

The backwash valve is located near your pool pump and filter unit. It is important to open this valve before starting your sand pool filter. This will allow any debris or dirt to be removed from the filter by flushing it out with water.

Step 4: Add Sand to Your Pool Filter

If you are starting a new sand pool filter, you will need to add sand to the filter tank. The amount of sand needed will depend on the size of your filter tank. Typically, it is recommended to use #20 silica sand. Follow the instructions on your filter system to determine the correct amount of sand to use.

Step 5: Turn On Your Pool Pump

After you have completed these steps, it is time to turn on your pool pump. Allow the water to circulate through the system for a few minutes before returning to the multiport valve.

Step 6: Set Your Multiport Valve to “Rinse”

Once the water is circulating through the system, set your multiport valve to the “rinse” position. This will allow any remaining debris or dirt to be removed from the sand pool filter.

Step 7: Return Your Multiport Valve to “Filter”

After you have set your multiport valve to the “rinse” position and allowed water to circulate through the system for a few minutes, it is time to return your multiport valve to the “filter” position. This is the position your valve should remain in unless you need to backwash or perform maintenance on your sand pool filter.

Conclusion

Starting a sand pool filter may seem like a daunting task at first, but with these simple steps, you can have your filter up and running in no time. Remember to turn off your pool pump, locate your multiport valve, open your backwash valve, add sand to your filter, turn on your pool pump, set your multiport valve to “rinse”, and finally, return your multiport valve to “filter”. By following these steps and maintaining your sand pool filter, you can ensure that your pool will remain clean and clear all summer long.
