What is the best flow-control device at the pole end? My cheap, 1/4" blue-and-white plastic ball control valve is a little stiff and awkward.
Thanks,
Gordon :)

Valves at the brush end will always put a backpressure onto the pump and cause pressure switch problems.
Take a look at the new Varistream from Williamson Pumps on http://www.williamsonpumps.co.uk/varistreamspec.pdf.
This unit controls the speed of the pump, and also will automatically compensate for the height the brush is at, giving a constant control of the flow.
