Pool filters are essential to keeping a pool clean and healthy. However, sometimes sand can be blown back out of the filter into the pool, making it difficult to maintain clean water. There are several possible explanations for why this might happen. Let’s explore the reasons why a pool filter can blow out sand and what you can do to prevent it.
Clogged, Damaged, or Blocked Filter
If the swimming pool filter is clogged with debris or dirt, it can cause the pump to work harder and thus blow out sand. If the pool pump is damaged, sand can be blown out into the pool as it will no longer be able to adequately filter it out.
Your Pool Filter may be Full of Sand.
When the pool filter is full of sand, it will eventually blow out the sand through the pressure relief valve. When sand accumulates in the filter, it will put too much strain on the sand pool filter system and eventually blow out sand through the pressure relief valve. This sand must then be replaced for optimal performance of your pool’s filtration system.
The pool filter is vital in keeping the pool clean and clear, but over time, its effectiveness can be reduced due to dirt and sand accumulating in the filter. Over time, parts of the filter can become worn down, making them less effective at filtering out sand. This can lead to the swimming pool pump working overtime and pushing sand back into the pool.

Wrong Filter Size:
If the sand pool filter is not the right size for the pool, it can increase the pressure on the pump and cause sand to be blown out. For example, if a filter is too small for the size of the pool, it can increase the suction pressure, which in turn leads to sand being blown back out into the pool.
Improper filter installation can lead to problems, such as sand being pushed back into the pool due to incorrect alignment or loose connections.
Low or Too Much Water Flow:
If the water is not circulating properly, it can prevent a filter from working correctly and cause sand to blow out. Too much flow rate: If the flow rate is too high, it can cause an overflow of sand that then spills out into the pool.
High Suction Pressure:
If an incorrect or too high suction pressure is set on the filter, this can cause an excess of sand to be drawn into the filter and then blown back out.
These are just some of the potential reasons why swimming pool filter blows out sand. It’s important to make sure that all the parts of a filter are in good condition and installed properly to ensure it works correctly and doesn't blow out sand. If you think this may be happening in your pool, contact a professional for help. They can diagnose the issue and fix it.
Keeping a close eye on the pool sand filter can help you save time, energy, and money, as regular maintenance will prevent more serious repair costs down the line.
