How does sand get in my pool?
Hear this out loudPauseInside a sand filter tank, water pours into the sand from the top. As it makes its way down through the sand, small debris and contaminants are filtered from the water. If, for some reason, one or more of the laterals crack, sand will easily pass through and be sent into your pool along with the clean water.
How does a sand filter work in a pool?
Each lateral tube is filled with tiny holes that are large enough to allow water to escape but small enough to keep the sand inside. When water pours into your filter from the top, it works its way through the sand, filtering out small particles and cleaning your pool water.
