Chemical Injectors There are two (2) types of chemical injectors to get the soap into your pressure washer. Downstream injectors allow you to apply soap, and then rinse, without ever having to switch the machine off. This can be achieved with multiple nozzle options, including roll-over nozzles and other double nozzles. This soap is applied at low pressure. Upstream injectors apply soap at … Read More
Detergents Different types of detergents work best for various applications. Detergents, as surfactants, bind their hydrophobic end to the dirt, while simultaneously binding their hydrophilic end to the water, bringing what normally wouldn’t mix with water into contact with it. This allows the water to actually clean the surface of whatever it is you’re cleaning, even th… Read More
Inlet Filtration Choosing the proper inlet water filter is the first step in protecting your pump from potential damage, and keeping your tips from getting clogged. The best choice of filter will vary. In order to choose the best inlet filter, you need to determine the application it will serve. Filtration Level Each filter will be equipped with a screen designed to remove particulates f… Read More
Lances The lance is the part of the pressure washer connecting the trigger gun to the nozzle. Lance length, material, and flexibility are important aspects to consider when purchasing a lance, or even when choosing which lance to use for the specific job you’re doing. Longer or telescoping lances exist for when splash-back could be an issue, or when the surface you’r… Read More
Nozzles Nozzles are one of the two most important parts of a pressure washer; the other part being the pump. Nozzles control both the pressure and the concentration of the water jet coming out of the gun. Using different nozzles allows the water jet to be more or less concentrated, either cleaning a smaller or larger area of the surface you’re cleaning. Drain Cleaning Nozzl… Read More
Pressure Gauges Pressure gauges warn operators when the pressure washer may have faulty or worn packings, or when the nozzle at the end of the lance is worn down. Both of these factors affect the pressure in a pressure washer, and can lead to costly repairs if not diagnosed and fixed early on. Pressure Gauges Read More
Pressure Hoses The hose you buy for your pressure washer is extremely important. It's no ordinary hose; these are pressure hoses. They have to match or exceed the pressure rating of your pressure washer’s output, or you risk bursting. Poor quality hoses kink easier, are less flexible, and are liable to burst with little or no notice. Most people prefer 50’ hoses over 25&rsquo… Read More
Pressure-Reducing Valves Some pumps are sensitive to high inlet-water pressure. If the inlet-water pressure is over 60 PSI, your pump may need pressure-reducing valves to keep the pump from wearing out. Pressure Washer Valves Read More
Rotary Brushes Rotary brushes are used to help scrub things away, whether it be bird poop on your car or caked on grime on the side of buildings. Natural bristle rotary brushes are softer, and can be used on painted surfaces, while nylon bristles are for more heavy duty tasks, like cleaning brick or cement. Rotary brushes are low-pressure types to make them compatible with soap injectors. P… Read More
Sand Blasting Heads Sand blasting heads allow a small amount of sand to enter the water stream, adding extra abrasiveness to the wash and making it significantly more effective. Always be sure to wash out your lines after using a sand blasting head to prevent any mishaps during future uses. It’s also important to note that you must have a certain amount of power in your pressure washer if yo… Read More
Trigger Guns Trigger guns are one of the most abused parts of a pressure washer. It’s best to get quality trigger guns when starting a project to avoid replacements and other inconveniences later on in your project. There are two (2) types of trigger guns: front entry and back entry. Front entry guns are used for more low-pressure applications, such as washing cars or roofing. B… Read More
Unloader Valves Without unloader valves, your pressure washer would explode. Okay. Maybe not explode. But the results would not be pretty or functional. When you’re not using your pressure washer, and the machine is still on, pressure can continue to build. An unloader valve releases the pressure built up while the unit is inactive. Flow-Actuated Unloader Valves Some unloader valv… Read More
