Fleck 5600 12 day backwash only valve on a 9" by 48" tank.
Include 1 cu. ft. of BIRM for oxidized iron removal and valve by pass option.
Used to remove Iron water source that is oxidized already, or that you are adding "air" to the water before it reaches this filter tank.
The system uses nothing but water to clean the BIRM.
The Gravel ( 15 lbs. ) and BIRM ( 1 cu.ft. bag ) will need to be poured into the tank using a funnel we provide.
We can not ship the tank full as the gravel layer must be on the bottom.
NOTE: Comes with 3/4" stainless steel by pass option ( Fleck part # 60040SS ), if you need the by pass to have 1" threads, please make this selection when ordering.
