The Do's and Don'ts of Buying Pressure Washers

Industrial cleaning requires heavy-duty equipment. The cleaning equipment being used at home is not effective when utilised in an industrial setting. There is different cleaning equipment online to help businesses in more than ways than one, but nothing performs best as a pressure washer when it comes to removing mould, grime, mud, dust, dirt, loose paint, and graffiti from surfaces or parts of a building, vehicles, and so on. This high pressure mechanical sprayer performs wonders. It is beneficial for a company because it reduces the need for manual cleaning and makes the cleaning process faster and more efficient.

There are different types of pressure washers, and there are types that are aptly suited for industrial applications. Buyers need to determine which type of pressure washer is best for their needs. A pressure washer also has different parts, and knowing what to look for in these parts help the buyer purchase a quality pressure washer. The do's and don'ts of buying a pressure washer, having covered different aspects of the machine, prevents buyers from getting a pressure washer of an inferior quality with features not suited to the buyer's needs.

Pressure Washers

A pressure washer is an effective cleaning machine that can be used in an industrial setting, depending on its type. The machine, in its high-pressure form, is also used in dust-free cutting of concrete and some metals. The volume of a pressure washer or the amount of water it can release can be expressed in litres per minute. The pump of a pressure washer is responsible for creating pressure, which is expressed in pounds per square inch or PSI. Basically, a pressure washer is composed of three essential elements: a motor that drives a pump, a high-pressure hose, and a trigger gun-style switch.

How It Works

A pressure washer creates velocity and high pressure when releasing water. The pump of a pressure washer can only draw amounts of water that a water supply can provide. Nozzles, which connect to the trigger gun, can vary based on the intended application. There are nozzles emitting a thin jet of water that spirals around rapidly in a cone pattern, and there are nozzles ejecting water in a fan pattern or a triangular plane.

To make cleaning more efficient, there are pressure washers, along with a specific nozzle, which combines a chemical such as a detergent. These pressure washers can be a low-pressure injector that combines a chemical in water before water enters the pump or a high-pressure washer that introduces a chemical after water leaves the pump.

Pressure washers must be used with caution. Anyone who is sprayed accidentally with a pressure washer can have the flesh, if too near the nozzle, removed from the bone. That is how dangerous pressure washers are. Also, a pressure washer, if aimed directly at the tarmac can break up the material.

Types

The energy that a pressure washer consumes can determine its type. The different types of pressure washers include:

Aside from the above washers, there is a special type, called an insulator washer, which is much larger and is mounted on a truck. It is used to remove pollution or contamination from overhead power line insulators to prevent high voltage short circuits.

Types of Pressure Washers Depending on its Grade

A pressure washer can also be categorised based on its grade or its capacity in water pressure, which is expressed in PSI; water flow, expressed in litres per minute or LPM; and cleaning units or CU, which is the amount of water pressure multiplied by the rate of water flow. Such categories are basic, advanced, and special. The table below shows the differences of the three categories.

Feature

Basic

Advanced

Special

PSI

1,300 to 4,000

1,000 to 4000

1,000 to 7,000

LPM

4.5 to 15

5 to 15

5.6 to 30

CU

1,560 to 16,000

2,000 to 16,000

2,000 to 28,000

Water Type

Cold

Cold

Cold, warm, and hot

The number of a pressure washer's PSI determines how efficiently it can break the bond between the stain and the surface. The larger the LPM, the more area a pressure washer covers. The CU is an important consideration because higher water pressure in combination with higher amounts of water coming out of the nozzle makes cleaning more efficient.

The Do's of Buying Pressure Washers

First-time buyers of pressure washers may find the process tedious and confusing. These pointers help buyers know what to do when buying a pressure washer.

Do Know the Type of the Pressure Washer

As a rule of thumb, a petrol- or propane-powered pressure washer is great for outdoor applications because it offers better mobility than an electric type. An electric pressure washer, on the other hand, is best suited for indoor applications because it does not emit exhaust and runs quieter than its gas-powered counterpart.

Do Buy a Pressure Washer with a Ground Fault Interrupter

Buy a pressure washer that has a ground fault interrupter. A ground fault interrupter is designed to protect users of a pressure washer from electric shocks. Some pressure washers of this type require a 20-amp circuit.

Do Check the Water Supply Requirements of the Pressure Washer

Check if the water supply is enough to match the specification of the machine. Inadequate water supply can cause cavitation damage to the pressure washer. Usually, regular water flow provided locally is adequate, but it is not a bad idea to check.

Do Choose a Pressure Washer with the Right Parts

Buy a pressure washer with parts that are right for the intended application. As discussed, the type of nozzle determines how water comes out of the pressure washer, and there are cleaning projects that require specific water coverage.

Do Make Sure That Replacement Parts Are Available

Do buy a pressure washer with replacement parts that can easily be found. Parts, due to wear and tear, eventually need replacement. If it is hard or impossible to find replacement parts, it may be costly and burdensome to repair the pressure washer.

Do Know the Life Expectancy

The pump of a pressure washer has a certain life expectancy. It is always useful to buy a pressure washer that discloses the life expectancy of the pump so buyers know when to expect replacement.

Do Know the Type of Drive System

Consider the drive system of the pressure washer. A belt drive system, which can withstand daily use for a considerable time period, is typically recommended for industrial setting with daily, heavy-duty applications.

The Don'ts of Buying Pressure Washers

Buyers should also know not only what to do but also what not to do when buying a pressure washer. These pointers are a helpful guide.

Don't Forget to Check the Length and Quality of the Hose

Do not get a pressure washer hose that is short. A 7.5 metre pressure washer hose can be too short for many applications. The recommended hose length is 15 metres. Furthermore, make sure that the hose that comes along with the pressure washer has the right PSI rating to match the machine. A hose with poor quality tends to break easily and is vulnerable to leakage.

Don't Buy a Pressure Washer with a Low Water Pressure or Flow Rate

Do not buy a pressure washer with low water pressure or psi. Because the equipment is to be used in an industrial capacity, it should be able to provide at least 4,000 PSI. Although a 2,000 PSI pressure washer is enough for removing grime and grease from decks, sidings, and concrete, only a 4,000 PSI washer is sure to remove stubborn stains and paint, as well as cover large areas when cleaning.

In addition, do not buy a pressure washer that has a low flow rate or LPM. A pressure washer with a higher LPM covers more areas in a shorter amount of time compared to those with lower LPM.

Don't Assume That a Higher Price Equals Better Quality

Don't think that the quality of a pressure washer is relative to its price. There are pressure washers that are priced exorbitantly but do not deliver well. The important thing is to select a brand, ideally regardless of price, that has a capacity to perform in all the intended applications. It is also wise to compare different models before making a purchase.

Buying Pressure Washers on eBay

There is a wide variety of pressure washers on eBay. You can select from different brands, such as Karcher, Draper, Sealey, and much more. Whether you are looking for a new or used pressure washer, you can find it on the website. Pressure washers can come in a home or industrial variety on eBay, and if you are looking for an industrial pressure washer, there is a lot to choose from on the site.

To find pressure washers quickly on the site, just type in relevant keywords, such as "electric pressure washer" or "petrol pressure washer", into the search bar. There is also a way to filter your search according to preferences, such as the condition of the item, brand, and other things. It is always recommended to deal with top-rated sellers because they respond more quickly to queries or purchase requests. These sellers can be individuals or online shops within the site. Purchasing can be a hassle-free process if you do it on eBay.

Conclusion

An industrial-grade pressure washer is an effective cleaning equipment when removing grime, dust, paint, graffiti, and other things that stick to the surface of a building or vehicle. It is also used in dust-free cutting of some metals and concrete. A pressure washer's basic parts are a motor, a high-pressure hose, and a trigger gun-style switch. The type of the pressure washer depends solely on the power it consumes. The three most important things to consider when buying a pressure washer are its water pressure, water flow, and cleaning units.

When buying a pressure washer for industrial use, do not choose one that has low water pressure and water flow because that equipment cannot perform well in industrial cleaning. Also, the quality of a pressure washer is not always relative to its price. Buy a pressure washer that has a ground fault interrupter, the right nozzle for the intended application, and has replacement parts that can easily be replaced. Pressure washers are a requirement for any company who are conscious about the sanitation and aesthetic beauty of their buildings and other assets, and a pressure washer that is very efficient is a worthy investment.
