just wondered what you think is best way to control flow of water, i used to have a valve and a back feed back into the tank, cheap as well but im now trying the flow coming out straight from tank into pole, its like a jetwash but very quick and does a good job and i just use alot more water but i think its worth it, what does anyone else use, anyone say what those vari stream things are like are they worth it and easy to install.
