Introduction:

A pool filter is an essential aspect of any swimming pool, and a sand pool filter is among the best filter types you can use. It is an affordable, effective, and low maintenance option that can filter out contaminants and debris from your pool water to keep it clean and safe for swimming. In this article, we’ll take you through how to use a sand pool filter to maintain the quality of your swimming pool water.

Understanding the Sand Pool Filter:

Before we dive into the details, let's discuss what we mean by a sand pool filter. A sand pool filter is a type of mechanical filter that uses sand to filter out impurities from your pool water. The filter comprises of a tank filled with sand, a diffuser that evenly distributes water to the filter, an intake pipe that draws water into the filter, and a backwash valve that disposes of filtered water.

The Mechanics of a Sand Pool Filter:

Now let’s move onto how a sand pool filter works. As mentioned, water is drawn into the filter through an intake pipe and enters the diffuser. From there, it gradually makes its way down to the sand bed, which can filter out debris such as dirt, leaves, and other particles that are too small for the human eye to see. The clean water then flows out of the filter and back into the pool through a return pipe.

The Importance of Backwashing:

Using a sand pool filter requires routine backwashing, which is the process of discharging dirty water through the backwash valve. This is necessary to clean the filter bed and remove debris that has built up over time. To do this, switch off the pump and turn the backwash valve handle to the ‘backwash’ position. After a few minutes, switch on the pump and let it run for approximately two minutes. You can then switch off the pump and turn the valve handle back to the ‘filter’ position.

Frequency of Backwashing:

The frequency of backwashing depends on how often you use your pool and how dirty it gets. As a general rule, most pool owners opt to backwash their sand filter once a week. However, this can vary depending on the specific filter and the pool use. It is recommended that you consult your filter manual for more instructions as they vary amongst manufacturers.

Filter Maintenance:

Sand filters are known for their low maintenance, but that doesn’t mean they don’t require maintenance at all. As mentioned earlier, backwashing is key to ensuring that your filter continues to function properly. It's also important to keep an eye on the pressure gauge, which is a component that indicates how much pressure is built up within the filter.

When the pressure gauge reads 8-10 psi higher than the normal operating pressure, it’s time to backwash the filter. Additionally, you should always inspect the sand periodically to ensure that it has not become clumped or clogged. If this happens, you will need to replace the sand with a new batch.

Conclusion:

Using a sand pool filter is an effective way to keep your pool water clean and safe for swimming. Now that you understand how to use a sand pool filter, you can rest easy knowing that you’re equipped with the knowledge needed to keep the filter functioning properly. Remember to backwash the filter regularly and maintain its components regularly, and you’ll have a clear, sparkling pool to enjoy for many years to come.
