From easy DIY solutions to cautionary tales of neglecting maintenance, we’ll cover everything you need to know about safeguarding your investment and ensuring your machine is ready for use in the coming springtime. Learn how to winterize your pressure washer with some simple steps.

Why winterize your pressure washer?

The water inside the pump, hoses, and other components might freeze in cold weather, resulting in cracks, leaks, and even complete failure. The consequences of not winterizing your pressure washer can be costly and time-consuming. If you live in an area with freezing temperatures, your machine is at risk of freezing and cracking pipes, damaging the pump, and rusting metal components. Even if you don’t live in a cold climate, neglecting to maintain your pressure washer properly can shorten its lifespan significantly.

There are several reasons why you should winterize your pressure washer:

1. Freezing temperatures may damage the pump and its parts.

2. The water left for a certain period in the machines may cause corrosion.

3. To ensure it’s ready to use in the springtime when you need it the most.

4. To save money on repairs or replacement parts down the road.

5. To prolong its overall lifespan.

The best time to winterize your pressure washer is before the first frost or freeze in your area. It gives you plenty of time to properly clean and dry the machine and add any necessary protection against corrosion or freezing temperatures.

6 Steps: How to winterize a pressure washer

Step 1: DRAIN THE GAS

Find the gasoline shutdown valve, which is probably on the engine’s side. It might have a miniature representation of a gas station pump next to it or the word “fuel” printed close by. Switch it off.

If your pressure washer has no fuel shut-off valve, you can empty the gas from the fuel tank into a gas can using a hand-operated siphon. If you still need to do so, take your pressure washer outside before turning it on. Keep the pressure washer on until it consumes all the fuel in the carburetor. It will likely take a minute.

STEP 2: STABILIZE THE GASOLINE TANK

Add a fuel stabilizer to the fuel tank so that the fuel tank doesn’t get clogged. Incorporate the stabilizer as directed by the manufacturer. To distribute the stabilizer throughout the fuel system, run the engine for two minutes before turning it off.

When purchasing fuel, it must have a fuel stabilizer added. Fuel resting in the pressure washer for more than 30 days cannot be preserved by adding a fuel stabilizer. Only the gasoline’s state is preserved when the stabilizer is administered.

STEP 3: FLUSH THE WATER OUT

Remove any water from the pressure washer system as the first step in winterizing it. Start by turning off the water supply, then briefly run the pressure washer to remove any leftover water. Then, remove the nozzle and fire the cannon to let any water trapped inside out. Next, drain the spray wand and hoses. It guarantees that no water will be left over during winter storage to freeze and cause harm.

STEP 4: DRAIN THE ENGINE OIL & ADD FRESH OIL

DRAIN: Find the oil drain plug towards the engine’s bottom. Place the plastic container below the drain plug. The drain stopper can be removed by loosening it with a socket wrench and setting it aside. Give the oil 10 minutes to drain into the pan. Find the oil filling port and open it. Put the port opening where your slanted funnel is in it.

ADD: The funnel will dispense the SAE 0w-30 synthetic motor oil (or the brand your owner’s manual recommends) into the port. Little by little, add it. Stop pouring occasionally, take the funnel out, and use the dipstick on the oil cap’s bottom to check the oil level. When the oil level on the dipstick is accurate, replace the oil cap.

STEP 5: ADD LUBRICANTS TO MOVING PARTS

Lubricate the moving parts of your pressure washer to keep it functioning at its best over the winter. The pump, engine, and any other parts mentioned in the owner’s manual should all receive a thin coat of lubricating oil. When you restart using the pressure washer, this keeps the parts from corroding.

STEP 6: RUN A PUMP FLUSH AND ADD A PUMP SAVER

Put clean water through the pump for a few minutes before cutting off the power source to flush it. It will clear the pump of any debris that could have gathered there while it was in use.

The last step is to add a pressure washer pump saver. Pump Saver antifreeze keeps the pump from becoming damp, preventing it from freezing. Additionally, it makes post-storage starting simple and stops mineral deposits from forming. To fill the chamber, apply the pump saver through the garden hose inlet of your pump. Let it remain there throughout the winter and drain it in the spring.

Alternatives to Winterizing a Pressure Washer

To protect it from freezing temperatures: your pressure washer must be winterized. Various solutions can help safeguard your equipment if you cannot do so.

• A heated area, such as a garage or shed, is one place to keep your pressure washer. It will aid in maintaining the temperature inside the appliance above freezing and avert any damage.
• Investing in a pressure washer winterizing kit is an additional option. These kits often include a winterization ingredient for the detergent tank and a specific pump oil made to survive subfreezing temperatures. Even if your pressure washer is exposed to below-freezing conditions, this can help safeguard it.
• Drain all fuel tanks and rinse the detergent tank before storing your pressure washer. It will shield it from chemical traces that can harm it in cold weather.

Winter maintenance and regular inspections

• Even though your pressure washer is in storage throughout the winter, you should regularly check on it to ensure it’s still in good shape. Look for any damage indicators, like leaks or cracks. Check the hoses, the pump, and the other parts for potential problems. Early detection of issues enables you to stop them from growing and doing more extensive harm.
• Start the engine of your pressure washer sometimes throughout the winter to maintain it functioning at its best. It maintains the internal parts oiled and prevents the accumulation of stale fuel. Start the pressure washer and run it briefly without using it, as directed by the manufacturer. This straightforward maintenance procedure might help maintain your machine’s functionality and durability.

Safe storage advice for winters

Selecting the Best Location

The ideal site must be chosen while keeping your pressure washer throughout the winter. Find a place that is dry, well-ventilated, and shielded from the cold. Ideal locations would be a garage or shed. The pressure washer shouldn’t be kept outside because exposure to freezing temperatures can cause harm.

Guarding Against Freezing Temperatures

Freezing temperatures can damage your pressure washer in areas with harsh winters. You have a few options for how to keep it safe. One is to take the pressure washer indoors, where it is always warm enough to use. For further defense against freezing temperatures, you can also use a space heater or insulating blankets made especially for pressure washers. These precautions guarantee that your pressure washer is protected from the damaging winter weather.

Cover pressure washer

It’s wise to carefully cover your pressure washer during the winter months of storage to protect it from dirt, moisture, and other potential dangers. Use a breathable cover that fits securely over the machine to shield it from dirt and stop moisture buildup. This straightforward procedure contributes to the longevity and cleanliness of your pressure washer.

How to Handle a Freezing Pressure Washer

If your pressure washer freezes, turning off the power should be your first step. After turning off the power, you can defrost the appliance by pouring hot water over the frozen components. Never use a torch or other high-heat source to attempt to defrost a machine because you risk damaging delicate parts. Before resuming usage of the machine after it has defrosted, make sure to dry off any damp components.

Conclusion

Winterizing is essential to save your investment and ensure the pressure washer lasts as long as possible.
