If you are looking at pressure washers, but are new to the market, some of the terminology may also be new to you. Understanding what those terms mean can make shopping around a whole lot easier, then you know what you are looking at instead of reading a box and wondering. Let’s take a look at some common terms that are used in identifying different features of pressure washers.

Adjustable pressure regulator – this regulator allows the user to vary the pressure of the spray.

Adjustable spray / multi-reg nozzle – a multi-reg nozzle allows you to adjust the angle of the spray with a turn of the tip. These nozzles also allow for the low pressure application of chemical and cleaning solutions.

Axial cam – these types of pressure washers uses a cam to transform the rotary motion of the motor into the reciprocating motion of the pump’s pistons. An axial cam system has fewer parts than other systems so are normally less expensive.

Belt drive system – a belt driven system uses pulleys and belts to slow the speed of the pump. This type of system allows for a longer pump life, but some efficiency is lost due to the additional friction caused by the belts and pulleys. There is also additional maintenance in keeping them belts adjusted.

Ceramic vs. non-ceramic plungers – the plunger is a primary part that moves back and forth between the rubber seals to create the flow and pressure of the system. Industrial grade pressure washers use ceramic plungers because they are very smooth, extending the life of the seals so they do not wear out.

Chemical injector – this allows chemicals or soap to be injected into the water stream, resulting in faster and easier cleaning. Without a chemical injector, the user must switch to a special soap nozzle.

Direct drive – in these types of pressure washers, the pump is connected directly to the engine. The pump and engine spin at the same speed. This system is very simple, having few moving parts which makes it less expensive. However, the disadvantage is that the bearings get more wear and tear which reduces the life span of the pump.

EZ start adjustable unloader – this eliminates the pressure in the pump when you start it up, it makes pressure washers easier to start and causes less damage to the starter motor.

Gearbox pumps – these types of pressure washers have a gear reduction box between the motor and the pump, so they run at about half the speed of direct drive pumps. WIth less need to replace the seals and valve as often, there are less maintenance expenses.

GFCI – this only applies to electric pressure washers, it stands for Ground Fault Current Interrupter which protects the user from accidental electrocution.

GPM – stands for Gallons Per Minute which is part of the measure of the power of the washer. The great the GPM, the faster and more powerful the cleaning capacity of the unit.

This is just the first part of the helpful vocabulary when shopping for a pressure washer. There are many other terms about pressure washers, and we will take a look at more of them next time.

As winter approaches each year, it can be important for homeowners to have a repair person from a Heating contractor At Eastside Heating & Air Conditioning come to their home to inspect their heating system to ensure that it is not in need repairs and ready for the colder temperatures that the following months will bring. While there are some maintenance tasks a homeowner my be able to handle on his or her own, it can still be a good idea to have a professional handle the work, as they can give the unit a thorough inspection. Often this can result in repair issues being discovered before they cause a significant problem.

A technician will generally first want to check the thermostat on the unit and make sure it is working properly. They can do this by using a secondary temperature gauge such as an infrared thermostat gun and then comparing it to the temperature reading on the thermostat. If these two do not match, the thermostat will need to be adjusted accordingly.

Once the thermostat is tested, the Heating contractor At Eastside Heating & Air Conditioning will need to inspect the burner on the system. Many times the burner can be checked for problems just by looking at the color of the flames it produces. If flames are blue and steady then the unit is operating properly. If the flames are yellow or orange and flickering, the burner may be dirty can the unit is not getting enough air to operate properly. A repair person will need to spend time cleaning the burner and the burner tubes on the unit if this is the case.

The blower on the system can also become very dirty as well. Having a dirty system not only can be dangerous in some cases but it can cause the unit to operate much harder, which can decrease the length of time the unit will be in operation. In addition, dirty units require more power to operate and this can have a direct impact on the energy costs for the home. Cleaning the blower system is the best way to keep the unit clean. The filter will need to be inspected and replaced if it is dirty. The blower should be vacuumed out, both inside and out using a shop or home vacuum cleaner. Vents or grilles should be cleaned with a stiff brush.
