The FlexiTank Blanking Cap allows you to open or close the ports in the top of the FlexiTank. The ports, when opened, allow for constant/flowing water supply to the FlexiTank. This enables the use of a recirculating system, rainwater diverter or constant/ regulated freshwater supply with FlexiTank.

The Blanking Cap must not be used in the main outlet port in the lower body of the FlexiTank.
