This check valve cap secures your jet tip system to the drag wand head that goes along with your carpet extractor. It holds in either a non-heated, or a heated jet tip, along with a check valve & strainer by screwing into the drag wand head. This is the system that dispense the solution from your wand. These check valve caps can often become pitted and corroded, making them hard to screw on and off of the wand head. At this point it would definitely be time to replace them. We recommend replacing your check valve caps every other time you replace your jet tips and check valves. Please take a look at the diagram below to understand which parts you might need. This listing is for Part A in the diagram. Part B is either a non-heated, or a heated jet tip. Part C is a check valve & strainer. You can find all of these parts and more in our complete category of drag wand jets & parts.
