Finding sand in your pool can be a frustrating experience, especially if you're unsure of its source. While a few grains of sand might not seem like a big deal, their presence often signals an underlying issue that needs addressing. Understanding what sand in your pool means and how to deal with it can save you time, money, and frustration.
Where Did All That Sand in the Bottom of My Pool Come From?
First and foremost, it's essential to confirm whether what you’re seeing is actually sand. Sometimes, algae can have a mustard-yellow tinge and can be easily mistaken for sand. If left untreated, algae can become a significant problem. To determine if the substance in your pool is sand or algae, use your pool broom to gently sweep through the suspected sand patch. If the water becomes cloudy, it’s likely algae, not sand. If this is the case, you should follow a guide for treating algae promptly to prevent it from spreading further.
If it turns out that it is sand, there are several possible external sources. One common but often overlooked source is wind. Wind can pick up sand and deposit it into your pool. Usually, this happens in small quantities, which are not a major concern. However, if you or a neighbour is undergoing earthworks or landscaping, sand or dust can become a significant issue. This situation is particularly common in new housing estates, where ongoing construction can lead to prolonged periods of sand and dust infiltration.
If you’re getting new paving installed around your pool or re-sanding existing pavers, sand might find its way into your pool during the construction process. In this case, it’s a good idea to talk to your paving team about minimizing the amount of sand that ends up in the pool. Although some sand in the pool is inevitable during such projects, it can be reduced by regularly sweeping the pool surrounds—always directing debris away from the pool edge—and by keeping the pool cover on as much as possible.
Possible Causes of Sand in Your Pool
Beyond external factors, sand in your pool could be a sign of an issue with your pool's filtration system. Here are the main causes to consider:
-
Broken Sand Filter A malfunctioning sand filter is one of the most common reasons for finding sand in your pool. Sand filters are designed to capture debris, but over time, internal components can wear out or break. If the lateral pipes or laterals at the bottom of the filter tank crack, sand can escape and enter your pool through the return jets. If you notice this happening, your filter needs to be inspected and possibly repaired or replaced.
-
Cracked Laterals The laterals are small, perforated pipes located at the bottom of the sand filter. Their job is to keep the sand inside the filter while allowing clean water to pass through. If one or more laterals crack, sand will begin to leak into the pool. Sand typically accumulates in small piles beneath the return jets, which is a tell tale sign that the laterals need to be checked. The good news is replacements are usually available and they are a replaceable part. If you cant find what you need, contact Surrey Dream Pools for assistance.
-
Newly Added Sand If you’ve recently added new sand to your filter, some excess may have escaped during the process. This situation usually resolves itself after a few filter cycles as the excess sand is flushed out. However, if the problem persists, it may indicate a deeper issue with your filter.
What to Do if You Find Sand in Your Pool
If you notice sand accumulating in your pool, the first step is to determine the source. Here’s how to troubleshoot and address the issue:
-
Inspect Your Sand Filter Turn off your pool pump and inspect the sand filter for any visible signs of damage, such as cracks in the filter tank, broken laterals, or issues with the multiport valve. If you're unsure how to inspect the filter properly, it might be worth consulting a professional.
-
Check the Laterals If you suspect the laterals are the problem, you’ll need to remove the sand from the filter to inspect them. This can be a messy job, but it’s necessary to prevent more sand from entering your pool. Replace any broken laterals before refilling the filter with new sand.
-
Vacuum the Sand After identifying and fixing the problem, thoroughly vacuum your pool to remove the sand. Use a pool vacuum designed to handle fine particles to ensure all the sand is removed.
-
Monitor the Situation After repairing your filter and cleaning your pool, keep an eye on the situation. If sand continues to appear, there may be an issue that was overlooked, and professional help might be needed.
Preventing Sand in Your Pool
Prevention is always better than cure. Here are a few tips to help prevent sand from getting into your pool:
- Regular Maintenance: Regularly inspect and maintain your sand filter to ensure it’s in good working condition. Replace the sand every 3-5 years, depending on usage.
- Proper Pool Cleaning: Ensure your pool cleaner is functioning correctly and that filter bags or cartridges are intact and installed properly.
- Environmental Protection: If your pool is near a sandy area, consider using a pool cover when the pool is not in use to minimize the amount of sand that can be blown into it.
Conclusion
Sand in your pool can be more than just a minor annoyance; it can signal a problem with your pool’s filtration system or be a byproduct of environmental factors. By identifying the source of the sand and taking appropriate action, you can keep your pool clean and enjoyable. Regular maintenance and proactive steps to prevent sand from entering your pool are key to maintaining a pristine swimming environment.
