How to Properly Store a Pressure Washer for Winter

Many people do not realize the importance of preparing their pressure washer for cold winter weather. If you bought one of the best pressure washers and wish to prolong the life of your equipment, there are several precautions that you should take before putting your pressure washer away for the season.

Why Do I Need To Store My Pressure Washer Properly For Winter?

Although it is possible to simply put your pressure washer in a shed or garage over the winter, people who live in colder climates where ice and snow are likely, you should seriously consider hibernating your pressure washer correctly.

Should you fail to take the correct precautions, your equipment may suffer from unexpected damage which will necessitate costly repairs, and these are unlikely to be covered by your product warranty as these generally exclude damage caused by failure to correctly store your washer during cold weather.

Luckily, hibernating your pressure washer is very simple and relatively quick to do.

How To Properly Store A Pressure Washer For Winter

  1. Ensure first that your machine is switched to the stop position.
  2. Disconnect the water supply hose and ensure that the water supply line is shut down.
  3. Detach both the trigger gun and the high-pressure hose. Make sure that they are fully drained.
  4. Turn on the motor switch and add an antifreeze solution to the float tank.,
  5. Use a different container that is also filled with an antifreeze solution for the detergent suction hose. If your pressure washer has different control settings, ensure that you have turned the detergent valve position to high to prevent the detergent line from freezing.
  6. Turn on the pressure washer and run it until the antifreeze solution escapes from the outlet.
  7. Turn the switch back to the off position.
  8. If your pressure washer is gas-operated, ensure any gas in the tank has been drained out as this may cause a blockage. Of course, you will not need to follow this step if you have an electric pressure washer. You should, however, if possible store both types of washer in a warm, dry location, preferably in a garage or basement with a storage cover if possible.

If you follow these steps carefully, your pressure washer should now be properly stored for the winter season.
