The appropriate washer should be selected according to the vessel diameter, filter media and required backwash flow rate.
Installation Information
The fitting connects to the compatible Clack control valve using the standard drain connection locking clip.
The drain line flow control washer is positioned within the fitting assembly and can be accessed by unscrewing the retaining nut.
Please Note: The V3008-04 is supplied without a silencer. The 9–25 GPM rating refers to the range of compatible flow control washers, not a fixed flow rate. The appropriate V3190 series flow control washer must be selected separately unless specifically included with the product.
