Store Your MPro 25 for the Winter

Winter is coming! Make sure your electric pressure washer is stored properly so it’s ready for action next year.

Disconnect Water & Relieve Pressure

1. Turn OFF the machine and unplug it.
2. Turn off your water supply.
3. Squeeze the trigger on the gun until all pressure is released from the hose and pump.

Drain All Water From the System

1. With the unit still unplugged, disconnect the high-pressure hose from the machine.
2. Disconnect the gun and wand from the hose.
3. Tip the electric pressure washer forward and backward to let any remaining water drip out of the pump and inlet.

Even a drops left inside can freeze and crack the pump housing.

Add Pump Saver / Antifreeze

This is the most important step! Use pump saver, RV antifreeze, or pressure washer antifreeze.

How to apply it:

1. 1. Connect the pump saver bottle to the water inlet (garden-hose side).
   2. Press or squeeze the bottle until antifreeze begins to flow out of the outlet.
   3. Once it flows steadily, the pump is fully protected and internally lubricated.

Benefits:

1. 1. Prevents freezing
   2. Protects seals and pistons
   3. Prevents corrosion
   4. Keeps the pump lubricated during storage

Storing the Hose, Gun & Nozzles

Even if water doesn’t freeze inside them, moisture can cause corrosion or mold.

1. Drain all hoses thoroughly.
2. Store them uncoiled and dry.
3. Remove nozzles and let them dry.
   

Store the Pressure Washer Properly

1. Keep it in a dry, indoor place if possible.
2. Avoid uninsulated garages below freezing unless the pump saver was applied.
3. Store the machine upright.

When You’re Ready to Use It Again

1. Just reconnect your hoses.
2. Flush clean water through the machine for 20–30 seconds before use.
3. You do not need to remove pump saver. It will harmlessly rinse out.
