I know you have bought from me before Nathanel, but I have noticed in the last few exchanges, and not neceserly about the Aquatap you have been very negative towards me. No way is it sour grapes on my part because of your previous comment, as I like negative comments as much as positive ones, it gives me a chance to either overcome them, or explain them away. Ok that out the way here is an answer to your criticism.
The pole won't turn the valve off if its turned as long as the brush is not against the glass or something else. Only when the brush is held still will twisting the bottom of the pole turn the water on and off. Even if there was a case where the water was on when you wanted it off, or vice versa, it would only then take a second to turn it back on/off.
