Winter Warrior: Prepare Your Pressure Washer for Winter Storage

Fact Checked By Daniel Wood | Post Updated On: December 17, 2023

Winterizing your pressure washer is crucial to protect it from the cold temperatures during storage. By following these winter storage tips, you can ensure that your pressure washer is in good condition and ready for use when spring arrives.

As the winter season approaches, it’s important to start preparing for winter storage. Freezing temperatures can cause damage to your pressure washer if it’s not properly winterized. Taking the time to follow these steps will help protect your investment and ensure that your pressure washer performs optimally when you need it again.

First, it’s essential to thoroughly clean your pressure washer. Remove any dirt, grime, or debris that may have accumulated during use. This will prevent clogs and corrosion. Be sure to drain any remaining water from the system, including the pump, hoses, and nozzles. Any water left in the system could freeze and cause cracks or other damage.

Next, check all the connections and fittings for any signs of wear or leaks. Replace any damaged parts to prevent further issues down the line. Lubricate the pump and other moving parts as recommended by the manufacturer to ensure smooth operation after storage.

Additionally, it’s important to protect your pressure washer from the elements. Store it in a dry and secure location, away from direct sunlight and extreme temperatures. Consider covering it with a waterproof tarp or using a storage container to shield it from moisture and dust.

Lastly, remember to consult the manufacturer’s guidelines for specific winter storage recommendations. Each pressure washer may have unique requirements based on its make and model.

By taking the necessary steps to winterize your pressure washer, you can rest assured that it will be ready to tackle your cleaning tasks when the warmer months return. Don’t let winter catch you off guard – prepare your pressure washer for winter storage now!

Steps to Winterize Your Pressure Washer

To properly prepare your pressure washer for winter storage, follow these steps:

  1. Prepare the fuel system: Start by adding a fuel stabilizer to the gas tank and running the pressure washer for a few minutes to circulate the treated fuel through the system. This will help prevent the fuel from degrading over the winter months.
  2. Flush the system: Disconnect the water supply and remove any attachments. Connect a short length of hose to the pressure washer’s inlet and insert the other end into a bucket of clean water. Start the pressure washer and allow it to run until clean water is flowing through. This will remove any remaining cleaning agents or debris from the system.
  3. Protect the pump: Remove the high-pressure hose and spray gun from the pressure washer. Pour a small amount of pump lubricant into the inlet and pull the engine’s starter cord a few times to distribute the lubricant throughout the pump. This will help prevent the pump seals from drying out and cracking during storage.
  4. Drain the water: To prevent freezing and potential damage, drain any remaining water from the pressure washer. Start by disconnecting the water supply and running the pressure washer for a short period to expel as much water as possible. Then, remove the drain plug or valve and allow any remaining water to drain completely.
  5. Store in a dry, protected area: Once you have completed these steps, store your pressure washer in a dry and protected area. Cover it with a waterproof tarp or use a pressure washer cover to shield it from dust, moisture, and other elements during the winter months.

By following this winter storage checklist and performing regular maintenance, you can ensure that your pressure washer remains in optimal condition and is ready to tackle your cleaning tasks once warmer weather returns.

Build a Custom Pressure Washer Trailer

When it comes to pressure washing, having the right equipment and setup is essential for efficiency and convenience. One solution that can greatly enhance your pressure washing capabilities is a custom pressure washer trailer. With a pressure washer trailer, you can have a mobile and versatile setup that allows you to tackle various cleaning tasks with ease.

Option 1: DIY Pressure Washer Trailer

If you’re a handy person who enjoys DIY projects, building your own pressure washer trailer can be a rewarding experience. By customizing the trailer to fit your specific needs and preferences, you can have a setup that is tailored to your requirements. Here are the basic steps to get you started:

  1. Select a suitable trailer: Choose a trailer that is sturdy and has enough space to accommodate your pressure washer, water tank, and other necessary accessories.
  2. Design the layout: Plan the layout of your pressure washer trailer, keeping in mind the placement of components such as the pressure washer, hose reel, water tank, and storage compartments.
  3. Secure the equipment: Use appropriate fasteners and brackets to securely mount the pressure washer and other equipment onto the trailer to prevent movement during transport.
  4. Install water supply system: Set up a water supply system that includes a water tank, pump, and filtration system to ensure a steady flow of clean water to your pressure washer.
  5. Wire the electrical connections: Connect the pressure washer, lights, and other electrical components to the trailer’s electrical system.
  6. Add storage compartments: Include storage compartments on the trailer to store additional cleaning tools, hoses, and accessories.

Building your own custom pressure washer trailer allows you to have full control over the design and functionality, ensuring that it perfectly meets your requirements. However, it does require some technical skills and knowledge of trailer construction and pressure washing equipment.

Option 2: Ready-Made Pressure Washer Trailer

If the DIY route isn’t for you, consider investing in a ready-made pressure washer trailer. These trailers are specifically designed for pressure washing applications and come equipped with all the necessary components and features. With a ready-made trailer, you can skip the construction process and have a plug-and-play solution for your pressure washing needs.

When choosing a ready-made pressure washer trailer, consider factors such as the trailer’s weight capacity, water tank capacity, hose length, and overall durability. Look for reputable brands that have a track record of manufacturing high-quality pressure washer trailers.

Regardless of whether you choose to build your own custom pressure washer trailer or purchase a ready-made one, it’s essential to ensure that the trailer is properly set up for optimal performance and safety. Additionally, regular maintenance and inspections are crucial to keep your pressure washer trailer in top shape.
