How to Winterize a Pressure WasherWhether you have an electric or a gas pressure washer, it’s important to know how to store it properly so you still have the advantage of the warranty. By knowing how to store a pressure washer, you will be able to ensure that it keeps working the way it should and you won’t experience difficulties when you need to take it out of storage.

So, once the summer passes, it’s essential to winterize your pressure washer. Why is this important? Read on to find out! We’ll also go through the steps you have to take to winterize your unit.

Winterizing a Pressure Washer – Why Is It Essential?

You’ve heard that you should winterize your pressure washer, but why is it important to do so? Well, when you’re not using the pressure washer, the internal parts may be affected by the cold temperature, which would influence the way the unit works. Because of that, you have to make sure you lubricate the internal seals so they stay in good condition throughout the entire winter.

Can You Leave a Pressure Washer Outside?

No matter if you have a portable pressure unit or a bigger washer, you need to store it correctly so it doesn’t get damaged. In this regard, you may be wondering if leaving a pressure washer outside is a good idea or not.

You should never, under any circumstance, store your pressure washer outside. If it rains, the unit can be damaged by water. This can cause corrosion in the long run. These units were not made to resist heavy rain and huge amounts of water. This is why you should make sure you store the pressure washer in an enclosed space, where rain cannot reach it.

Pressure washers usually come with disclaimers saying that you should not use the unit to clean itself either, and that’s pretty self-explanatory.

Can Pressure Washers Get Wet?

Can Pressure Washers Get WetFor the most part, it’s not recommended to allow a pressure washer to get wet, especially when we’re talking about leaving the unit in the rain or using the washer to clean it.

But some pressure washers are constructed to be more resistant, and as a result, they can handle way more “abuse” compared to other products. So, even if they are splashed with water, they may not be damaged as long as they’re heavy-duty units.

If you want to make sure, check the pressure washer’s IP rating so you find out if it can deal with situations where it gets wet. Keep in mind, though – if there’s a heavy rain ongoing or the ground is wet, you should not use it even if there’s a high enough IP rating.

Also, you should be careful when it comes to electric pressure washers because you risk electrocuting yourself if they get wet. A gas-powered unit would be a much better choice if you want to use it in damp conditions.

On top of that, if there is no IP rating in the user manual, then you should avoid allowing the unit to get wet.

Then it’s time to turn on the unit and pull the trigger with the low-pressure nozzle. Allow it to operate for a short amount of time, respectively a few minutes. Turn off the hose and get rid of it from the pump inlet, and then eliminate all the water in the system by pulling the trigger.

  1. Sort Out the Pump System – Pour some tap water into a bucket, then take the hose for detergent suction and place it in the bucket. Then, attach the hose and turn on the tap.

This will remove all the water from the system.
  2. Store the Washer – Make sure the pressure washer can be stored indoors, in a place that is not damp. The location should also be warm enough to not allow the unit to freeze. It may also be essential to add some pump saver.
