When Should You Change Sand in Pool Filter?

As a pool owner, keeping your swimming pool clean and well-maintained is a priority. One essential part of keeping your swimming pool clean is having a properly working pool filter. Over time, however, the sand in your pool filter becomes less effective and needs to be replaced. In this article, we will go through everything you need to know about changing the sand in your pool filter.

Why Replace Pool Filter Sand?

It might seem like an added expense to replace the sand in your pool filter, but over time, it becomes a necessity. As the water flows through the filter, dirt and debris accumulate in the sand, which over time reduces the effectiveness of the filter. Over time, the filter will not be able to clean the water as well as it used to when it was new.

How Often Should You Replace Sand in Pool Filter?

The frequency of changing the sand in your pool filter depends on the usage and water chemistry of the pool. On average, it is recommended to replace the sand in the pool filter every 5 years. However, if the pool has high usage or unbalanced water chemistry, the frequency of changing the sand may be more frequent.

Signs It's Time to Change Your Pool Filter Sand

While the standard recommendation is to change the sand in your pool filter every five years, sometimes you might need to replace it more frequently. Here are five signs you should look out for which indicate it is time to replace your pool filter sand:

1. The Pool Water Looks Dirty

If you notice that your pool water is not looking as clear as it used to, then it could be a sign that you need to change the sand in your pool filter. The dirty water could be a result of the filter not working efficiently to clean the water.

2. Poor Water Flow Rate

If the water is not flowing from the pool jets as it did previously, then it’s a sign that there is something wrong with the pool filter. Sand may have clogged the filters and hindered water flow.

3. Frequent Clogging of Pool Accessories

Clogging of the skimmer or pool cleaner is another sign that your pool filter sand may need replacement. If the filter is not functioning properly, dirt and debris build-up may clog the pool accessories more often.

4. High Maintenance Costs

If you find that you are frequently spending more money on pool maintenance due to severe algae or other issues, it could be a sign that your filtration system is not working correctly. A filter that is functioning efficiently would prevent unwanted chloramine levels and lead to fewer chemical treatments.

5. Abnormal Sounds or Vibrations

If you encounter unusual noises or vibrations caused by your pool pump, it may indicate that the filter is not correctly working due to clogging of sand or other debris.

How to Replace Pool Filter Sand?

If you've decided to change your pool filter sand, it’s recommended that you enlist the services of a professional pool maintenance company. However, if you are confident you can do it yourself, below is a step-by-step guide to help you replace it yourself:

1. Shut off the pump

When changing the sand in the pool filter, you must first turn off the pool pump and turn off the valves.

2. Drain Filter

Direct the drain pipes towards a safe location before releasing the drain plug to remove the old sand.

3. Remove Multi-Port Valve

4. Remove Old Sand

Using a plastic scoop or container, carefully remove the sand from the pool filter and dispose of it properly.

5. Add New Sand

Add the same amount of sand, which was previously in the filter, filling the filter section completely, ensuring the right sand product is used.

6. Reassemble

Reassemble the filter in the reserve order, and check for proper sand distribution before running the pump.
