How to Operate a Sand Pool Filter

If you own a swimming pool, you know how important it is to keep the water clean and clear. One of the most important components of your pool maintenance routine will be the filter. The sand pool filter is a popular option for homeowners because it's affordable, effective, and easy to use. In this article, we'll cover everything you need to know about how to operate a sand pool filter.

Understanding Sand Pool Filters

Before we get into how to operate a sand pool filter, let's start with what it is and how it works. Sand pool filters are filled with silica sand, which acts as a filtering agent. As dirty water passes through the sand, the particles and debris get trapped, while the clean water is released back into the pool. Sand pool filters come in different sizes and capacities, so you'll want to choose one that's appropriate for the size of your pool.

Before You Begin

Before you start operating your sand pool filter, there are a few things you'll want to check:

1. Make sure the pool water is at the right level. The water level should be high enough to cover the skimmer and the pool's bottom, but not so high that it overflows.

2. Check the skimmer and pump baskets. Empty them of any debris, such as leaves or twigs, that could clog the filter.

3. Check the pressure gauge. The pressure gauge will tell you when it's time to backwash the filter. If the pressure is too high, it means the filter is dirty and needs to be cleaned.

Operating Your Sand Pool Filter

Now that you've checked everything, it's time to get started.

1. Turn off the pump. Before you do anything, turn off the pool pump.

2. Switch the multiport valve to "backwash." The multiport valve is the control valve on the sand filter. It directs the flow of water and controls the functions of the filter. When you switch it to "backwash," the water flow is reversed, so the dirty water is flushed out of the filter and sent to waste.

3. Turn on the pump. Turn on the pump and let it run for about two minutes. You'll see the water coming out of the waste line become cloudy at first, but it will become clearer as the filter is backwashed. Keep an eye on the pressure gauge. When the pressure drops to around 8-10 psi, it's time to stop backwashing.

4. Switch the multiport valve to "rinse." Once you've finished backwashing, switch the multiport valve to "rinse." This step is important because it gets rid of any residual dirt or sand that may be left in the filter.

5. Turn on the pump. Let the pool pump run for about 30 seconds in the "rinse" position.

6. Switch the multiport valve to "filter." Once you've finished rinsing, switch the multiport valve back to "filter." This is the normal operating position for the sand pool filter.

7. Turn on the pump. Turn on the pump again and let it run. Check the pressure gauge to make sure the pressure is within the normal range (around 10-15 psi).

Maintaining Your Sand Pool Filter

Operating your sand pool filter is just one part of maintaining your pool. You'll want to make sure you're also taking steps to keep your filter in good condition.

1. Backwash the filter regularly. How often you need to backwash your filter will depend on how often you use your pool and how dirty the water gets. As a general rule, you should backwash once a week.

2. Keep the filter clean. Once a year, you'll want to open up the filter and clean out any sand or debris that may be clogging it. You can do this by carefully removing the sand and rinsing out the filter tank.

3. Replace the sand. Over time, the sand in your filter can become compacted or worn out. When this happens, you'll need to replace the sand with fresh silica sand.

4. Check the pressure gauge. Keep an eye on the pressure gauge and backwash the filter when the pressure is too high.

5. Use the right chemicals. Using the right balance of chemicals will not only keep your pool water clean and clear, but it will also help your filter work more efficiently.

Conclusion

Operating a sand pool filter is a straightforward process that just requires a few steps. Make sure you check the water level, skimmer and pump baskets, and pressure gauge before you get started. Backwash the filter regularly, keep it clean, and use the right chemicals to keep your pool in top condition. With a well-maintained filter, you'll be able to enjoy clean and clear pool water all summer long.
