Winterize & Store Your Pressure Washer


Share |

Posted In


More efficient and much more powerful than a garden hose, a pressure washer shoots a strong jet of water to plow through dirt and grime, leaving surfaces clean. Pressure washers — also called power washers — tend to get used heavily during the spring but not as much during autumn or winter. 

Protect your investment through cold weather by storing your pressure washer properly. Watch our 2 minute video on how to winterize and store your Briggs & Stratton pressure washer or read on for an overview of this procedure. 

Protect Your Engine 

Properly winterize your pressure washer by taking good care of your Briggs & Stratton engine. 

Gasoline goes stale in about 30 days, and stale gas can lead to component failures and costly repairs. Additionally, 90% of all fuel sold in the U.S. is an ethanol blend. Ethanol-blends deteriorate almost the moment they are pumped, and can break down in the fuel tank causing rust, corrosion, and gun/varnish build-up. Add Briggs & Stratton’s Advanced Formula Fuel Treatment and Stabilizer before storing your pressure washer for the winter to protect your engine. Run the engine for 2 minutes to circulate the fuel stabilizer throughout the system. Then, turn off your pressure washer. 

Flush Out the System
 
When putting your pressure washer in storage, it is important that no water remains in the pump. 

To start, place the injection tube into a pail of clean water and run the pressure washer on the low pressure setting for 2 minutes. Dependent upon your climate and the make of your pressure washer, you may want to do an anti-freeze flush too. Then, turn off the engine and the main water supply. 

Turn the spary gun in a safe direction and squeeze the trigger to release trapped pressure. Then, engage the trigger lock on your spray gun. 
Once the unit cools down, disconnect any attached high pressure or garden hoses. Then, drain the water from the hose, spray gun, and nozzle extension. Use a rag to wipe off the hose. Store all accessories pull the recoil handle about 6 times to empty the pump of all liquids. 

Maintain the Pump System 

Once you have removed all liquids from the pressure washer pump system, move to a clean, dry place. Lay down a tarp and make sure you are wearing eye protection. Now, fill your pressure washer with with a pump saver oil by connecting a short garden hose (about a yard) to the inlet adapter. This will help prevent rust, freeze damage and keep pistons and seals from drying out. 

Finally, pull the recoil handle twice to complete the process. 

Storing Your Pressure Washer
 
Store your pressure washer in a cool, dry place, cleaned of dirt, grime, and moisture.

IF WATER HOSE IS NOT CONNECTED WILL THIS CAUSE ENGINE NOT TO START

Asked by: NICH
Never start the engine on a pressure washer without the hose and water on. You will damage the internal parts of the pump. The two most common reasons a pressure washer engine will not start is too much pressure in the pump or a dirty carburetor. You will want to relieve the pressure in the pump before starting the engine. Next clean out the carburetor.

Pressure washer extremely hard to start not impossible but once it is running & warmed up seems to run & start good.

Asked by: Jackall
First make sure you are releasing the pressure from the pump before starting the engine. The water should be running, to release the pressure just engage the trigger on the gun and let the water flow. Then start the engine. If you are doing this, check the fuel. Make sure it is clean fresh fuel. If it is older fuel it can thicken and start to clog the carburetor which will cause hard starting to a no start condition.

Ever since new my briggs pressure washer blows heavy smoke when started then cleans up. Usually this would be valve stem seals. Thanks

Asked by: livebaitdifter
First check the fuel and the oil level. Make sure the oil level is not overfilled. Also check to make sure there is no fuel in the oil. Next check the fuel, is it fresh? If not change out the fuel. Next you can check the valve seals.

Is it normal for the pump to become almost to hot to touch during operation?  Oil level is fine.

Asked by: IanG
The pump will become warm. If it is heating up too much, check the thermal relief valve on the pump. It may not be functioning properly.

The pressure washer will start but when I try to use the gun the engine dies

cleaned the carb, cleaned fuel lines and tank, still won't stay running
Asked by: Sandie
It sounds like the pump is building too much pressure. It could be the unloader is sticking and not bypassing. I would recommend the unit be taken to an authorized service center for diagnostic and repairs.
