The easiest Water Fed Pole TAP in the industry ... 

Regardless your extended pole length, simply kink your RADIAL HI-FLO TUBE in the KINK, and the flow stops.

RADIAL HI-FLO TUBE does not remember being kinked, so you have no damage to the tube.

There are two ways to use kink - either grab the tube, and kink it OFF, pull it out for ON.
