What does an unloader valve do? It's attached to a gas pressure washer pump and its job is to safely control/direct the flow of water into your pump. To keep your pump from being damaged. When you pull the trigger on your spray gun, the unloader valve opens wide to send your water through the pump. Then the pressurized water flows through your spray wand tip. And, when you stop spraying, it closes and it redirects the water through a hose and it is recycled through the pump again.
