Where to Put Sand in Pool Filter

Every swimming pool owner knows how important it is to have a properly functioning pool filter. Without a pool filter, your pool water could become stagnant and unhealthy, leading to various issues like algae growth, murky water, and bacterial infections. Pool filters come in various types, including diatomaceous earth (DE), cartridge, and sand filters. Sand filters are the most commonly used pool filter, as they are easy to maintain and operate. However, if you are new to pool ownership, you may be wondering where to put sand in your pool filter. In this article, we will explain everything you need to know about sand filters and where to put sand in your pool filter.

Understanding Sand Filters

Before we jump into where to put sand in your pool filter, let's first understand what a sand filter is. A sand filter is a large tank filled with pool-grade sand, which traps small particles and debris as water flows through the sand bed. When the sand becomes clogged with debris, it needs to be cleaned through a process called backwashing. During backwashing, water is pumped through the sand filter in reverse to flush out the trapped debris.

Choosing the Right Sand

Now that you understand how a sand filter works, it's time to choose the right type of sand for your pool filter. Pool-grade sand is specially designed to trap small debris particles without clogging the filter. Regular sand, on the other hand, will clog quickly and require frequent backwashing. When selecting sand for your pool filter, ensure that it is labeled as pool-grade sand or filter sand. You can purchase pool-grade sand at most pool supply stores or online.

How Much Sand to Use

Once you have purchased your pool-grade sand, you need to determine how much sand to put in your pool filter. The amount of sand required varies depending on the size of your sand filter tank. Check your owner's manual or contact the manufacturer to determine the appropriate amount of sand for your filter. If you are unsure, a general rule of thumb is to fill the tank about three-quarters full with sand.

Now that you have the appropriate amount of pool-grade sand, it's time to put it in your pool filter. Before you start, ensure that your filter tank is clean and free of debris. To fill your sand filter, follow these steps:

Step 1: Turn off the pool pump - Before you begin filling your sand filter, turn off the pool pump.

Step 2: Remove the filter lid - Using a wrench or pliers, remove the filter lid assembly.

Step 3: Remove the old sand - Carefully remove the old sand from your filter tank. Dispose of the old sand properly.

Step 4: Add the new sand - Using a funnel, slowly pour the new sand into your filter tank. Be careful not to spill any sand into the pipe or overflow tube.

Step 5: Reinstall the filter lid - Once you have added the new sand, reinstall the filter lid assembly.

Step 6: Turn on the pool pump - Once you have reinstalled the filter lid assembly, turn on the pool pump. Your sand filter is now ready to use!

Tip 2: Clean the filter tank - At least once a year, clean your filter tank to remove any trapped debris and prolong the life of the filter. Follow the manufacturer's instructions for cleaning your sand filter.

Tip 3: Check the sand level - Periodically check the sand level in your filter tank. If the level is low, add more sand as needed.
