To assist the filtering from a tank into the inlet port of the pressure chamber of a sprayer, an additional pumping structure is attached to the pumping mechanism of the sprayer. A hose extends into the tank of the sprayer and draws fluid from the tank into the additional pumping structure. Fluid is pumped from the additional pumping structure via the hose to provide a jet of fluid upon a filter over the inlet port. The jet of fluid flushes the filter and retards the accumulation of debris thereon, thereby retarding the clogging of the filter. |
