What You Should Consider When Buying Pressure Washers

Performance

CETA, or the Cleaning Equipment Trade Association has a methodology called GPM for calculating various ratings of performance of pressure washers. When searching for a washer, consulting the CETA rating will provide the best determination of overall performance. A GPM rating of 3.8 earns a product the CETA certification.

Other performance indicators are UL or Underwriters Laboratories and CSA also known as Canadian Standards Association. These two organizations are not as common as CETA but they offer both performance and safety ratings for units.

Cleaning consultants can also be found in most cities and offer advice on performance of units. Several of these individuals have the products in their possession and will give demonstrations of the strengths and weaknesses of the unit as well as help you determine which unit will be best suited for your needs.

Level of Maintenance Required

All pressure washers need routine maintenance that will vary depending on the time of year and how long it has been since the unit was last used. Different types of maintenance should be done before using the unit, after using the unit, and during long periods when the unit is not being used at all. Oil changes are one of the most needed forms of maintenance for both the engine and the pump.

Seals around the pump and valves should also be checked regularly. If the unit is self-heating, coils should be checked regularly. Hoses that are too old or have slight damage or cracks should be replaced as they are a safety hazard. The more the unit is used, the more maintenance it will need.

Nozzles

Most pressure washers come with their own nozzle attachments whether they are quick-change manually or quick-change within a single nozzle attachment. These nozzles are used for specific purposes and often function best at specified PSIs. Nozzles are also color-coded to help you identify the PSI. The more focused the nozzle, the more pressure and damage this nozzle can do.

Nozzles are usually not covered by warranties. Be sure that when you buy either replacements or extra tips that they properly fit the spray gun. It is safest to purchase from the same manufacturer and confirm with them that the nozzle will fit. Buying nozzles that do not fit can result in damage to the washer and/or to the object(s) being washed.

Pump Capacity

Pressure washers generally come with one of the two types of pumps – reciprocating or normal rotary. Reciprocating pumps must use either a diaphragm, piston, or a plunger whereas normal rotary pump uses gears, lobes, screws, or vanes. Both types of pumps can create high pressure.

Depending on the manufacturer, the pump can either be a wobble, an axial, or a triplex plunger. An axial plunger tends to have a shorter life span of around 200-400 working hours whereas a wobble’s life span is closer to 500-800 hours. A triplex pump has the longest life span of all three and will often last 10x longer. Axial plungers cause stronger vibrations. Wobble plungers take a longer time to cool, and triplex plungers have the highest cost.

Tire Types

Pneumatic tires are the most popular types of tires for pressure washers for a good reason. These tires withstand and help absorb the shock of different terrains. Not all pneumatic tires are created equal however, as the way in which they are attached to the frame and the material will impact the tire’s effectiveness.

The tire size is not always important, but rather how they are built in relation to the unit itself. Those tires which are oversized will generally hold the frame better. The positioning of both the engine and the pump can impact the effectiveness of the tires and usually require that the tires be larger than normal, to hold the unit steadily.

Other Key Considerations

Cost- Electric power washers run at a lower cost than gas-powered pressure washers by nearly $200-$300. Electric power washers can range between $300 to $2500 approximately, depending on the pump and engine types. Gas-powered washers on the other hand can run between $800 to above $6,000, depending on the pump and engine.

Refund Policy- Warranty and refund policies are important red flags to look out for. While at first glance, many companies appear to offer some sort of limited warranty, upon reading the fine print, consumers find that the warranty is easily voided. Often, the voiding occurs by simple everyday user errors. There are also different terms and conditions for commercial use versus non-commercial use washers, and frequently you can find a different warranty for commercial use that is more limited compared to non-commercial warranty. It is important to check refund policies with both the manufacturer and the distributor and make sure you fully understand your warranty terms.

Final Thoughts

A pressure washer should be purchased only after considering the job at hand as well as your specific needs. The highest PSI delivery may be inappropriate for your particular needs and might cause harm if not fitted well for the job at hand. At the same time, those units which do not deliver enough PSI will be a waste of money as it will not get your work done. Take time to figure out what you will use the washer for, follow reviews and you will not be disappointed. Also, be sure to always review the warranty and refund issues, so that you stay covered in most cases of malfunction.
