Top Tips for Winterizing Your Pressure Washer: A Step-by-Step Guide


As winter approaches, it's important to prepare your pressure washer for the cold weather to prevent damage and ensure it’s ready for use when the temperatures rise again. This comprehensive guide will walk you through the essential steps for winterizing your pressure washer, including the pump, hose, and other vital components.

How to Winterize a Pressure Washer Pump

The pump is the heart of your pressure washer, and proper winterization is key to preventing costly repairs.

Steps to Properly Winterize a Pressure Washer Pump

  1. Flush the System: Start by running clean water through the washer to remove any detergent or debris.
  2. Drain the Pump: Disconnect all hoses and allow the water to drain completely from the pump.
  3. Add Pump Saver: Use a pump saver to protect internal seals and prevent freezing. Follow the manufacturer’s instructions for application.

Importance of Pump Saver when Winterizing

Using a pump saver is crucial as it helps to lubricate and protect the internal components of the pump from freezing temperatures, preventing cracks and other damage.

Winterizing Your Pressure Washer Hose

Proper care of the hose is essential to avoid cracks and leaks caused by freezing water.

Proper Drainage of Water from the Hose

  1. Disconnect the Hose: Remove the hose from the pressure washer.
  2. Drain Completely: Hold the hose vertically to ensure all water drains out.
  3. Store Properly: Coil the hose loosely and store it in a dry, frost-free location.

Using Antifreeze to Protect the Hose

For extra protection, you can run a small amount of RV antifreeze through the hose. This step ensures that any residual water won’t freeze and cause damage.

Electric Pressure Washer Winterization Guide

Electric models require special attention due to their electrical components.

Winterizing Steps for an Electric Pressure Washer

  1. Disconnect from Power: Ensure the unit is unplugged from any power source.
  2. Drain Water: Follow the same steps for draining the pump and hoses as with gas models.
  3. Protect Electrical Components: Store the pressure washer in a dry place, away from moisture.

Using a Pump Saver for Electric Models

Electric pressure washers also benefit from pump savers to protect internal seals and components.

Safety Precautions for Winterizing an Electric Pressure Washer

Always ensure the unit is completely dry and free from any water to prevent electrical hazards when you use it again.

How to Safely Store Your Winterized Pressure Washer

Proper storage is just as important as the winterization process itself.

Tips for Maintaining Your Pressure Washer During the Winter

  1. Clean the Unit: Wipe down the pressure washer to remove dirt and debris.
  2. Store Indoors: If possible, store your pressure washer indoors in a dry, heated area.
  3. Cover the Unit: Use a protective cover to keep dust and moisture away.

Essential Steps in Winterizing a Power Washer

Beyond the pump and hose, other components need attention too.

Adding Stabilizer to the Fuel System

  1. Add Fuel Stabilizer: Mix a fuel stabilizer with the gasoline in your pressure washer.
  2. Run the Engine: Run the engine for a few minutes to circulate the stabilizer through the system.

Protecting the Pressure Washer Wand Assembly

  1. Drain Water: Ensure no water remains in the wand.
  2. Store Properly: Keep the wand in a dry place, preferably with the rest of the pressure washer components.

Ensuring Proper Winterization of Pressure Washer Nozzle

The nozzle is a critical component that can be easily overlooked.

How to Disconnect and Clean the Nozzle Before Winter

  1. Remove the Nozzle: Disconnect the nozzle from the spray wand.
  2. Clean Thoroughly: Use a nozzle cleaning tool or a small brush to clear any debris.

Using Antifreeze to Prevent Freezing of Nozzle Components

Apply a small amount of antifreeze to the nozzle to prevent any remaining moisture from freezing.

By following these detailed steps, you can ensure that your pressure washer is properly winterized and protected from the harsh winter conditions. This preparation will help extend the life of your equipment and keep it running smoothly for years to come. Happy winterizing!
