- Drill a hole as low as possible into the side of the five gallon bucket, slide the spigot through and secure to the bucket.
- Place the bucket on a sturdy surface above the pressure washer.
- Connect one end of a hose to the bucket and the other to the water inlet of the pressure washer.
- Connect the pressure washer hose, without the gun to the machine and bring the end into the five gallon bucket.
- Add one gallon of RV Anti-freeze and three quarts of water to the bucket (normally you mix 50/50 but you will be getting water out of the pump to make the other quart)
Okay, that’s done! Now, open the flow of the anitfreeze (or squeeze the bottle or press the button) into the pressure washer and wait for the anitfreeze to come out of the pressure hose and back into the bucket. Once this done, your pump hase been winterized and your pressure washer should be safe for the winter. If you have a lid for the bucket, put it on securely and you can reuse the antifreeze next year. Note: you do not conenct your pressure washer hose for this step.In the spring, connect a water hose to the machine and and the pressure hose to the machines outlet. Put the pressure hose into the bucket and start the machine, letting the antifreeze run into the bucket. Once you see water coming from the hose, shut down the machine and re-seal your bucket until the fall. Is that it? in the Spring, when you put your power washer into service you should run a Pump Saver through it to lubricate the pistons of the pump, the manifold and the seals. Since you have read this much about winterizing your power washer, we have one more word of caution for you. Your pressure washer is NOT intended to run without water flowing through it. You need to keep the trigger pulled and cool water running through the pump. If you let it run too long without the trigger pulled, you will damage the pump and turn your pressure washer into an expensive piece of junk.
