Tips & Advice
What is the difference between power and pressure washing?
Both power washing and pressure washing are used to clean and strip surfaces. The difference between power and pressure is that power washing uses hot water, and pressure washing uses cold water.
How often do pressure-washer nozzles need to be replaced?
Pressure-washer nozzles need to be replaced when they wear out. When the spray-fan angle (the width and range of the water spray) becomes compromised or reduced by wear and tear or damage, it is time to change it out. If the nozzle is clogged, a simple cleaning may work. Know that nozzles come with a variety of spray-fan angles, so you may need to switch it out if the job calls for a different spray fan.
How much do pressure washers cost?
Electric pressure washers can start as low as $99, or less if you find a good sale. Gas-powered pressure washers can start around $250. When shopping for a pressure washer, know your needs, such as hot vs. cold water, general purpose vs. industrial, heavy duty vs. light duty. These will affect your price point.
Can hot water be used for pressure washing?
Hot water can more effectively cut through grease and grime than cold water, but it can only be used in pressure washers specifically designed for hot water use. Units not designed for hot water can be damaged, as they are not equipped to handle the heat. They are also more expensive than cold water washers.
What is the best way to store a pressure washer?
When not in use for 30 days or longer, it is imperative to store your pressure washer accordingly to prevent freezing and/or internal oxidation, both of which can destroy your washer. The first step is to turn off or close the fuel line, then run the engine to clear the line and carburetor of fuel. Add fuel stabilizer to the gas tank if it still contains fuel. Next, connect a hose to the inlet of the pump and fill the hose with straight antifreeze (do not use a 50-percent mix). Run the unit until antifreeze comes out of the outlet (where the pressure hose would be attached). Your pressure washer is now winterized and/or ready for storage.
What is a direct-drive pressure washer?
Direct-drive pressure washers employ a hollow shaft that slides onto the drive shaft of the motor. The pump’s flange is mounted on the face of the motor, or on the shaft end of the motor. This direct-drive system means the pump’s operating RPM is the same as the motor’s RPM. This allows for a more compact system with fewer moving parts, making it a cheaper option. The big drawback is lower life expectancy due to the increased RPM strain.
What is a belt-drive pressure washer?
A belt-driven pressure-wash system uses a pump with a pulley mounted to a solid shaft and driven by one or more belts attached to a pulley on the motor. The advantages to this system over the direct-drive system is that they can operate at lower RPMs, thereby operating at lower temperatures. They also have increased vibration absorbency and have a longer life expectancy.
Do pressure washers require cleaning solutions in addition to water?
Pressure washers do not require cleaning solutions in addition to water. Most pressure-wash systems have soap or cleaning-solution reservoirs that can be filled and used for cleaning surfaces, but they are not a required part of a standard pressure-wash system.
On what types of materials can a pressure washer be used?
Pressure washers can be used on most any surface that needs to be cleaned or stripped. From vehicles, to sidewalks, to decks and walls, the ability to manipulate the pressure higher or lower allows pressure washers to accommodate most any reasonable surface.
How does a pressure washer work?
A pressure washer works by feeding water into a pump (either electric or gas powered) to create water pressure (measured in PSI - pounds per square inch). When combined with the designated water flow setting (GPM - gallons per minute) it produces a pressurized spray or “fan” of water that is emitted through a nozzle by operating the trigger mechanism.
