The basic pressure washer consists of a motor (either electric, internal combustion, pneumatic or hydraulic) that drives a high-pressure water pump, a high-pressure hose and a trigger gun-style switch. Just as a garden hose nozzle is used to increase the velocity of water, a pressure washer creates high pressure and velocity. The pump cannot draw more water from the pipe to which the washer is connected than that source can provide: the water supply must be adequate for the machine connected to it, as water starvation leads to cavitation damage of the pump elements.
Different types of nozzle are available for different application. Some nozzles create a water jet that is in a triangular plane (fan pattern), others emit a thin jet of water that spirals around rapidly (cone pattern). Nozzles that deliver a higher flow rate lower the output pressure. Most nozzles attach directly to the trigger gun.
Some washers, with an appropriate nozzle, allow detergent to be introduced into the water stream, assisting in the cleaning process. Two types of chemical injectors are available — a high-pressure injector that introduces the chemical after the water leaves the pump (a downstream injector) and a low-pressure injector that introduces the chemical before water enters the pump (an upstream injector). The type of injector used is related to the type of detergent used, as there are many chemicals that will damage a pump if an upstream injector is used.
There is low overhead when operating your own power washing business. The maintenance costs required for operating a pressure washer is typically low and insurance costs are not high when compared to other small businesses. Compared to owing a brick and mortar store, the pressure washing business costs and overhead doesn't even compare. You don't need to maintain a store or pay expensive monthly rental fees. The main monthly costs for a pressure washing business are insurance, marketing costs, and equipment maintenance.
The High pressure washing business isn't as competitive as many other small businesses. For example if you compare the pressure washing business with the landscaping business you will find far greater competition in the landscaping business. To verify this look in your newspaper for landscaping business ads and then check for pressure washing business ads. Chances are you will find less competition.
