How to Winterize and Store a Pressure Washer

How to Winterize and Store a Pressure Washer

Winterizing your pressure washer pump is a great way to ensure its longevity. First, disconnect all the hoses and the gun and wand assembly from the pressure washer, draining as much water as possible.


On a gas-powered pressure washer:
  • Attach the pump saver directly to the water inlet.
  • Turn the knob on the bottle to the open position.
  • Pull on the cord a couple times until the liquid coming out is 100 percent solution.

Now your winterizing is complete and it is safe to store your pressure washer in a garage or building that does not freeze.
