During the initial assembly, the large threaded end is pushed through the main port in the lower FlexiTank body. The washer and nut included with the Tap fitting are then placed over and tightened on the threaded end.
The Click-Fit Tap outlet that remains on the outside of the FlexiTank allows you to attach a standard 1/2” Green Hose Connector, a 1/2” Click Fit Tank Adaptor and Filter or a 1/2”-1/4” Click Fit Tank Adaptor and Filter.
***All FlexiTank and FlexiTank Pro models include a FlexiTank Tap as standard***
