What is an Unloader Valve?

The spray gun and unloader make up a two-part valve system that directs water into bypass and back to the pump or float tank. The spray gun shuts off the flow of water causing the unloader to recirculate the water back into the inlet side of the pump. This is called sending the water into bypass.
