Overview
The goal of winterizing your pressure washer is to protect it from freezing temperatures by keeping the internal seals greased while the unit is not in use.
Storing your pressure washer in freezing temperatures might harm its internal seals, potentially causing pipe system damage and rendering the machine useless. Cold weather, combined with any residual fuel in the tank and fuel lines, can cause pipe corrosion and other serious problems. It is critical to take steps to avoid such damage while storing.
How to winterize your gas pressure
Step 1: Begin by starting the engine and adding a gasoline stabilizer to the gas tank. Allow two minutes for the stabilizer to circulate through the fuel system.
Step 2: Next, empty the pressure washer’s water system to ensure that any residual water and cleaning detergent is entirely eliminated.
Step 3: Connect your garden hose to the pressure washer in the usual way. Fill a pail with fresh tap water and place the detergent feed tube in it. Turn on the pressure washer and pull the trigger to engage the low-pressure nozzle, allowing the detergent system to flush for a few minutes. Remove the water from the pump inlet and turn off the water supply. Pull the trigger once to ensure that the system is completely drained.
Step 4: If near-freezing temperatures are expected, it is critical to apply “Pump Saver” antifreeze to the pump’s input in the final stage. This precaution will protect against mineral deposits and cold weather-related issues.
How to winterize your electric pressure washer
Step 1: Because an electric machine lacks a gasoline engine, storage simply necessitates attention to the pump system.
Begin by submerging the detergent suction hose in a pail of running water. Connect the garden hose to the faucet. Start the pressure washer and spray water for two minutes while holding the gun steady. This procedure guarantees that the detergent solution is completely removed from the system. Remove the garden hose and pull the trigger again to thoroughly empty the system.
Step 2: Store the pressure washer indoors in a warm location to avoid freezing and potential damage to internal seals. Add “Pump Saver” antifreeze to the pump inlet to protect the pump’s inner seals.
FAQs
-
At what point does a pressure washer begin to freeze?
Maintain a temperature of at least 40 degrees. If it’s too cold outside, your pressure washer may be damaged, and the surfaces you’re cleaning may freeze.
-
What happens if a pressure washer is not properly winterized?
If winterization is not performed properly, a pump’s internal piping, hoses, seals, and other components may be injured, resulting in pump failure.
