In previous articles we talked about parts of a pressure washers, and explained in more detail about pressure washer unloader valves. Here we explain about types of pressure washer unloader valves.
There are three types of pressure washer unloader valves.
I received an email from a new business owner looking at how to effectively wash a fleet of cars. See the email below;
I’ve heard many people give recommendations on what apparatus to use when washing a fleet of cars, but I would like some guidance on HOW to wash a fleet of cars?
What have you found to be the most effective method of rinsing down and the wiping off the cars?
Any help would be greatly appreciated!
My answer to you is this….Use lots of pressure but keep a safe distance – remember the main reason behind using high pressure when rinsing cars is to remove the soap quickly!
In a previous article we talked about parts of a pressure washer, in this article we talk about specifics, namely pressure washer unloader valves.
Pressure washer unloader valves are the main “safety” in your power washer system. The most commonly used is the “pressure actuated” type valve. When the pressure gun trigger is released the valve senses the pressure build up and like a “traffic cop” it diverts the water flow from the pump outlet back into the inlet side of the pump this is called “bypass mode.” Without this critical component this closed-gun situation would build pressure to the point where it would stall the power source, rupture the gun, hose or even the pump itself.
I recently received an email from David, a concerned pressure washer from Florida. He asks:
Our deck is in good shape except in a few spots, it has mildew. I was going to pressure wash it
then seal it. Is this a good idea?Thanks,
David
Well David, if you have pressure treated pine as the surface of you deck , do not pressure wash it unless it is completely dirty and you have one of the smaller less powerful electric type washers. As they are less powerful, they generally wont have the power to do much harm.
In a previous article we showed the parts of a pressure washer, in this article we show how a pressure washer trigger gun works.
Generally the gun will have a 3/8? inlet port where the hose is attached and a 1/4? outlet port to the wand/lance (this is when 3/8? pressure hose is used). When the trigger is released the gun is said to be in “closed” position stopping the flow of water. When the trigger is squeezed it is in “open” position directing water to the nozzle once again.
Motor (Gasoline, Diesel or Electric)
Different sorts of motors are used for different types of pressure washers. It may also depend on the type and location of the applications. Most high power washers used in industrial works, commonly use gasoline or diesel motors. Because most industrial cleaning requires great amount of time, these motors could run much longer without overheating compared to their electric counterpart. And since most industrial works are done outdoors; and sometimes or mostly offsite, where there are no available electricity. The ones with electric motors are mostly used for light to moderate washing works (e.g. house, car, and small boats) and are the most excellent used for indoor applications because these motors do not emit harmful fumes.

Pressure washers are classified into following groups based on the type of fuel/energy they consume. But the most common of all types used for most common washing jobs is the electric and the gasoline.

The easiest way to learn how to use a power washer is to first understand how the power washing systems work. There are four basic elements of the power-washing process regardless of what machine or method you use. |
USES OF PRESSURE WASHER |

Pressure washing is in fact the process of breaking the bond between the dirt and the surface being cleaned. As we mentioned earlier, for the best results you will combine four essential elements. However, shortfalls do exist. Here is another example of how pressure washers work: let’s say you notice you have a little detergent left and you decide to decrease the amount injected through pressure washer. A cleaning solution decrease in this case will have a less effect on the debris being cleaned. Because of that, now you must work with other elements to make up for that loss. You have to increase the pressure, water temperature and the water volume. Even though, you are less likely to reach the same level of efficiency (by decreasing the amount of detergent), you will somewhat neutralize that loss.
