Common Terminology

Here are some common pressure washing terms. Don't worry if you don't get or understand one or more of these terms. We will go into them deeper in future sections:

1. PSI (Pounds per Square Inch): This is the unit of measurement for water pressure in a pressure washer. The higher the PSI, the more powerful the pressure washer.

2. GPM (Gallons per Minute): This is the unit of measurement for the water flow rate in a pressure washer. The higher the GPM, the more water the pressure washer can produce.

3. Nozzle: A nozzle controls the shape and direction of the water spray from a pressure washer. There are several types of nozzles, including adjustable, fan, and zero degree nozzles, each designed for a specific cleaning task.

4. Adjustable Nozzle: A type of nozzle that allows you to adjust the water pressure and pattern for different cleaning tasks. Adjustable nozzles are a versatile choice for pressure washing and can be used for a wide range of cleaning applications.

5. Turbo Nozzle: A type of nozzle that delivers water in a high-velocity spinning pattern. Turbo nozzles are designed to remove stubborn deposits and are often used in heavy-duty cleaning applications.

6. Rotary Nozzle: A type of nozzle that delivers water in a rotating pattern. Rotary nozzles are designed to increase the impact of the water stream and are often used for surface cleaning and concrete cleaning.

7. Fan Nozzle: A type of nozzle that delivers water in a fan-shaped pattern. Fan nozzles are commonly used for rinsing and general cleaning applications.

8. Detergent: A cleaning solution that is added to the water in a pressure washer to help remove dirt and grime from surfaces.

9. Surface Cleaner: A type of pressure washing attachment that creates a flat, circular spray pattern to clean large, flat surfaces like driveways and patios.

10. Soft-Wash System: A type of pressure washing system that uses a lower water pressure and special cleaning solutions to clean delicate or sensitive surfaces.

11. High-Pressure Hose: A hose that connects the pressure washer to the water supply. High-pressure hoses are designed to withstand the high water pressure produced by a pressure washer.

12. Wand: The wand is the part of the pressure washer that you hold to direct the water spray. Some wands have adjustable nozzles, while others have fixed nozzles.

13. Inlet Water Filter: An inlet water filter is a filter that is attached to the inlet of a pressure washer to remove dirt and other contaminants from the water before it enters the pressure washer.

14. Triplex Plunger Pump: A type of pump used in pressure washers that uses three plungers to generate water pressure. Triplex plunger pumps are durable and reliable, making them a popular choice for residential and commercial pressure washing applications.

15. Hot Water Pressure Washer: A type of pressure washer that uses hot water to clean surfaces. Hot water pressure washers are often used in industrial cleaning applications where hot water is needed to dissolve grease, oil, and other stubborn deposits.

16. Cold Water Pressure Washer: A type of pressure washer that uses cold water to clean surfaces. Cold water pressure washers are suitable for cleaning most outdoor surfaces, including decks, driveways, and sidewalks.

17. Electric Pressure Washer: A type of pressure washer that is powered by electricity. Electric pressure washers are typically smaller and less powerful than gas-powered pressure washers, making them ideal for residential use.

18. Gas Pressure Washer: A type of pressure washer that is powered by gasoline. Gas pressure washers are typically larger and more powerful than electric pressure washers, making them ideal for commercial and industrial cleaning applications.

19. Chemical or Soap Injector: A device that is used to add cleaning solution to the water in a pressure washer. Soap injectors are commonly used in residential and commercial cleaning applications to help remove dirt, grime, and other deposits from surfaces.

20. TSS (Total Stop System): A feature that automatically turns off the pump in a pressure washer when the trigger on the wand is not being pulled. This conserves energy and prolongs the life of the pump.

21. Unloader Valve: A valve in a pressure washer that regulates the pressure and flow of water. The unloader valve is typically located near the pump and is used to control the pressure and flow of water in the system.

22. Lance: A wand that is attached to a pressure washer. Lances come in various lengths and can be fitted with different types of nozzles, depending on the cleaning task at hand.

23. Quick Connect: A feature that allows you to quickly and easily switch between different nozzles and accessories. Quick connect fittings are a convenient feature that saves time and makes pressure washing tasks more efficient.

By understanding these common pressure washing terms, you'll be better equipped to select the right equipment and cleaning solutions for your pressure washing tasks.
