Description
Zoom on the Pressure-Pro PP4240H
In summary, the Pressure-Pro PP4240H is a heavy duty, commercial pressure washer, that offers an all-around versatile cleaning experience, and also:
- overall cleaning of hard surfaces, washing vehicles, and prepping surfaces for painting
- soft cleaning of delicate surfaces, and gentle cleaning for larger areas with low pressure
- applying detergents or chemicals, and rinsing surfaces afterward
Ahead are presented its power characteristics and design, its main features and any other additional features.
Power
The Pressure-Pro PP4240H's triplex pump, powered by an impressive 389cc (13 hp) engine, can provide a pressure of up to 4200 PSI (approximately 70 times more than a standard garden hose) and a flow of up to 4 GPM (values claimed by the manufacturer). Thus, the Pressure-Pro PP4240H achieves a cleaning power of 16800 Cleaning Units.
Starting the Honda GX390 engine of this gas pressure washer involves using a conventional pull-start method.
The pressure washer's steel tank has a maximum capacity of 0.3 gallon for storing gasoline.
Design & Handling
The Pressure-Pro PP4240H boasts great mobility, courtesy of its convenient hand truck design. The sturdy steel frame ensures the longevity of the assembly, offering stability and protection for internal components, even during rigorous use. The reversible handle offers further versatility, as its different positions make the unit less bulky when stored.
Weighing in at 115 lbs, it's safe to say this unit isn't lightweight, which might pose difficulties for users when it comes to lifting and transporting, particularly over uneven surfaces. Its 389cc Honda GX390 engine, the triplex pump and steel frame are mainly responsible for its heavy weight. However, the incorporation of two 10" never-flat wheels makes navigating the PP4240H less cumbersome, even on uneven terrain.
Main Features
Along with the Pressure-Pro PP4240H itself, the package also includes a spray gun, a wand, a pressure hose, 4 nozzles and a detergent injection feature, which are discussed in further detail below.
- Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The pressure washer automatically dispenses and mixes the detergent with the water when a soap nozzle is attached.
- Pressure hose: Utilizing a set of convenient hooks, the unit offers a convenient solution for storing the included 50 ft ⌀3/8" high-pressure hose when it's not in use, keeping it neatly organized.
- Spray gun and wand: The included classic ergonomic spray gun and its wand can be easily stored in a side hook.
- Nozzles: In the table below, you can see the 4 included nozzles alongside their respective recommended surface uses.
15° | 25° | 40° | Soap | |
|---|---|---|---|---|
| Concrete, brick, masonry | ||||
| Siding, gutters, house | ||||

| Lawn equipment, boat, RV |

Other Features
- Onboard storage: The Pressure-Pro PP4240H features a handy storage area, which allows you to neatly store nozzles and accessories and be always prepared by having everything needed at hand.
- Safety: Safety of operation is enhanced by a thermal relief valve (which helps to prevent internal pump damage), a low oil protection and a trigger lock mechanism (which prevents accidental operation).
- Accessories: Besides the usual owner's manual (opens in a new tab) and documentation to get you promptly started, the Pressure-Pro PP4240H comes with spray gun, wand, pressure hose, oil and soap hose.
