7 steps for winterizing and storing a pressure washer
The brutally cold winter months can wreak havoc on your pressure washer, causing expensive and sometimes permanent damage to the pump and fuel system. You can prevent freezing temperatures from damaging your pressure washer by following these simple steps.
Shut the pressure washer off and disconnect it from the water supply hose.
Disconnect the pressure hose from the spray gun and the high-pressure outlet on the pump. Drain any water from the hose, the gun and the nozzle extension. Wipe these items dry with a soft cloth.
Pull the recoil on the pressure washer about 6 times to remove any liquid in the pump.
Coil the pressure hose around the hose wrap on the pressure washer accessory tray.
Use Pressure Washer Pump Saver to keep the pistons and seals lubricated and to minimize freezing in the pump. Follow the instructions included with the product.
Drain the gasoline from the fuel tank—your owner's manual has instructions—and run it to burn off any remaining fuel. An alternative is to add fuel stabilizer to the tank of gas, which prevents the fuel from becoming stale and forming gum deposits that can damage the fuel system.
Store the pressure washer in a dry area.
