When it comes to pressure washer power, we consider several general categories. You can determine the amount of power you require based on the tasks you wish to complete. Keep in mind that a wider nozzle allows you to reduce the pressure and clean more quickly in almost all cases. However, you will not be able to force a pressure washer with insufficient power to perform beyond its maximum rated PSI or GPM.
- Washing vehicles, patio furniture (including wicker), and screens are examples of jobs requiring less than 500 PSI.
- Shutters with less than 2000 PSI – mildew/mould that is less noticeable – Grills – Screens – Patio/lawn furniture – Concrete/asphalt that requires limited cleaning
- The following products are available in 2000 – 3000 PSI: Pavement, Stains, Decks, and Fences. – Using smaller surface cleaner attachments to clean the surface – Concrete (driveways and sidewalks) – Siding – Mildew/mould that is lighter in colour.
- Decks and fences with a PSI of 3000 – 4000 – Constructive (driveways and sidewalks) use larger surface cleaner attachments when cleaning large surfaces. Stains that are deeper in colour on the pavement and siding – Paint stripping and graffiti elimination (at the top of the range) – Mildew and mould removal – Preparation for painting
- Paint stripping/graffiti removal at 4000 PSI or higher Concrete (driveways and sidewalks) should be cleaned with the most significant surface cleaner attachments available. – The surface of the pavement – Mildew/mould growth – Siding – Stains that are more intense Fencing & Decks – Decks & Fencing – Preparation for painting.
Every pressure washer requires a set of nozzles, a hose, and a wand to function correctly. Most of them use a standard quick connector, making it relatively simple to obtain a replacement if you ever need one.
Most pressure washers are equipped with 0 Degree, 15 Degree, 25 Degree, Degree, and soap nozzles, though some may be equipped with one or two fewer. That classification encompasses most of the applications you’re likely to encounter. They are colour-coded, and most models have a key on the frame that you can use as a guide. However, the angle is marked on the nozzle, even if it doesn’t.
The wands of pressure washers are probably the most vulnerable component of the entire system. They are naturally tube-shaped and must be lightweight to function effectively. They are also susceptible to bending, pinching, or flat-out breaking off when accidentally stepped on.
When you’re not using the wand, it’s best to hang it off the ground and avoid leaning it against a wall or trailer to keep it from breaking.
Each of the accessories has a PSI rating, just like the other accessories we’ve been talking about. It should work for you as long as you use the same diameter tube and quick connect nozzles (the majority are 1/4-inch tubes with 1/4-inch QCs). However, sooner or later, you’ll find yourself needing a replacement.
The final thing to look for is the connection to your spray gun; the threads must be the same size as the connection. Most connections are M22, and you can always double-check your manual to be absolutely sure.
Generally, the hose that comes with your pressure washer will be intentionally paired with it by the manufacturer. They are also rated for a specific PSI, just like the nozzles. When shopping for a replacement. Use that rating as a guide and try to find something close to what your current model has.
The pressure through a hose should not be greater than the pressure rating of the hose. The opposite is true: purchasing a hose designed to withstand a significantly higher amount of pressure than your pressure washer can significantly reduce performance as you increase hose diameter.
Consult the owner-manual to determine the appropriate hose diameter and length for your specific vehicle if you have any doubts.
Water from suitable pumps frequently lacks sufficient pressure and may not function properly with some pressure washers. Most pressure washers require a pressurised water supply, despite the pump and engine raising the pressure to a higher level. Double-check the manual to be sure, and contact the manufacturer if something is unclear in the manual.
A few electric pressure washers are labelled “commercial” to attract more customers. However, professional users do not have the pressure (PSI) or water flow (lpm) required. When choosing between commercial and residential pressure washers, you must stick to the petrol pressure washers. The engine and the pump, two primary components of a commercial pressure washer, play a significant role in defining a pressure washer.
Commercial pressure washers are powered by engines designed for the commercial market, such as the Honda GX series. Engines for residential models are designed to be lighter in weight.
With the pump, you’ll be able to complete the puzzle. Pumps for pressure washers for professional use and residential models are triplex pumps on commercial models and axial cam pumps on residential models. Many residential electric models incorporate a built-in pump. Still, we prefer an axial cam design separate from the rest of the system.
All-day long, we receive a large amount of debris on the surfaces of our driveways and sidewalks at our residences. And what better way to take care of this issue than with a pressure washer cleaner? When vehicles are caked with the results of mud, oil, or road salt on their surfaces, it is incredibly damaging to the paintwork. Obtaining a little help from a pressure washer, your ordinary garden hose can be transformed into the cleanest monster on the block, blasting away all debris and dirt.
