Although temperatures don’t get too frigid down in Texas, certain regions do experience some incredibly cold winter days. When temperatures drop, your pressure washing equipment is at risk if it isn’t securely stored. Even if you don’t intend to use your pressure washer in the cold weather seasons, it’s still important to take care of the machine so it’s good to go when spring arrives. Otherwise, you run the risk of having costly repairs when you’re ready to use it again. Save yourself the money and trouble with these winterizing tips!
Flush Out the System
Just as small amounts of gasoline will freeze in your car, water in your pressure water can freeze during winter, too. Water and leftover detergent must be removed from the system (depending on how cold it gets where you live, you may need to do a flush with anti-freeze as well). To easily flush out water and detergent, place the washer’s injection tube into a bucket of clean water. Run on a low pressure setting for a couple of minutes and then shut off the engine and main water supply. Release any trapped pressure by squeezing the trigger of the spray gun. Once the system has cooled down, disconnect all the attachments so they can dry, then make sure to drain the water from the hose, nozzle extension, and spray gun. You can drain any leftover water by pulling the recoil handle several times.
Manage Remaining Gasoline
You’ll also want to drain any remaining gas from the tank, or at least add a fuel stabilizer. Gasoline can gum up in cold temperatures, clogging the fuel lines or causing rust and corrosion. To prevent this, add a fuel stabilizer according to the manufacturer’s directions and run the machine for about 2 minutes so it can circulate throughout the system. Then, shut off the washer.
No matter what season it is, store your pressure washer in a cool, dry place where it won’t be exposed to dirt or excess moisture. Pressure washer covers are available at almost any home improvement store and will protect your washer from rust and damage from the elements. If it’s possible, storing your pressure washer in a heated garage or basement is ideal. However, even keeping it in an unheated shed or garage is much better than storing it outside.
Remember, a pressure washer is an investment. Like any investment (such as a car or a house), it’s important to take care of it and do the appropriate maintenance work to keep it running like new.
