The pressure washer was easy to winterize with the Karcher Pump Guard. Just took minutes to attache it to the pressure pump and pull the starter rope on the washer to pump out water and pump in antifreeze/lubricant solution

good product to protect pump.
Easy to apply. After use used the valve body as an extension to the water inlet which is hard to apply garden hose to because of clostnes to body of machine. Not what it was intended for but works great and with the use of hose washers, solvs the problem. Intend to use product to winterise machine in the fall.
