Why is there sand in my MARIMEX ProStar 6 pool?

If the sand fill is new, the grains in it might be smaller than the set size. In this case, repeat the back washing operation several times until the backwashing water is clean. Sand in the six-way valve (residues from backwashing) can also cause this issue. To resolve this, set the position to “Backwashing” and pump water to drain for approximately 30 seconds. Alternatively, the partition dividing the chamber for cleaned water might not be correctly installed, so check the installation. Finally, the bottom screen could be damaged, requiring you to change it.
