Abstract
A sewer cleaner having a water pump with a clutch-less connection to an engine draws water from a tank having a baffle with an orifice. A valve arrangement directs the output from the pump to either a hose on a reel or recirculates to the tank. The flow rate through the orifice is less than the operating output of the pump so that the recirculated water combines with that flowing through the orifice to permit operation of a hydraulic system to rotate the hose reel.
