Abstract
A system for flushing an airless sprayer essentially reverses operation such that the spray gun is immersed in a container of water or other solvent and that fluid is pulled through the pump and flushed through the normal inlet tube. The preferred embodiment attaches a fluid bar to the front of the spray gun to redirect the fluid for flushing. This reverse flushing action allows quicker flushing using less fluid.
