Brr! It’s Getting Cold
When water freezes, it creates pressure anywhere from 25,000 psi to 114,000 psi. Depending on the temperature, that level of force could destroy your pressure washer. When cold weather is approaching and it is very important to winterize your pressure washer before storing it in a place where the temperature is below 0°C/32°F.
All it takes is one night when you didn’t protect your equipment, and BAM! You need new hoses, a new pump, a new unloader, and new trigger guns or a new coil for your heater.
All this will cause you additional expenses, loss of time and contracts that could slip through your fingers at the start of the season.
«Winterizing your pressure washer is more than taking the supply line off your pump, letting the water drain out, and putting it in your garage.»
As a professional power washer, you most likely have a water tank, supply line, bypass line, high pressure pump, and unloader; and if you have a hot water pressure unit, a coil—and don’t forget the engine.
If you are storing the pressure washer for longer than 30 days, the engine needs to be winterized as well. Ethanol in today’s gasoline can cause major problems to your small engine. One problem is phase separation; this happens to gasoline containing ethanol that comes into contact with water, either liquid or in the form of humidity. Ethanol absorbs the water; and when it reaches the point of saturation, it will phase separate, causing water to form in your fuel tank, carburetor, and the engine float bowl.
Pressure Washer Components
There are three basic ways to prevent your pressure washer components from freezing up.
- Keep the components stored in a warm place,
- Drain or blow the water out with compressed air, or
- Winterize it with antifreeze.
Method winterizing takes time, BUT you will save on your equipment 💲💲💲.
It's the safest way to protect and store your equipment for the winter months.
Some companies have antifreeze systems built into their equipment, and with the turn of a couple of valves, they quickly and easily winterize the equipment.
If your equipment isn’t configured that way, try connecting a three-foot supply line to the inlet of your pump and placing it into a bucket of antifreeze.
