This causEs the check valve lo close, <br />initiating a siphon tliat draws polluted water lhroughout the full sur(ace area and volume of tho filter. <br />Thus, the entire filter cartridge is used to filfer wa:er throughout ihe duration oF the storm, regardless <br />of the water s�rface elevation in lhe unit.

Since some media <br />used is poleNially huoyant, a threaded connector affixed to the under-drain m�nifold (wilh glue or <br />other adhesive) is necessary to ensure thal ihe cartridge fsn'1 II(ted out of place. �pr the heavier <br />compost modfa, a slfp connector is used. <br />The StormFllter is also equippod wiih flow spreaders that trap Floating debris and sufface flims, eVen <br />during ovortlow condilions.
