Pressure washers utilize gas or electricity to power the pump, which forces water through the nozzle at a high pressure, states Lowe's. Gas pressure washers use a manual pull or electric starter to operate, and they are typically more mobile and higher powered than electric models. Electric models utilize a start switch and must be plugged in to an outlet to operate, which can affect their mobility. Owners should choose pump parts that are compatible with their operating system.

The pressure capabilities of the pressure washer are another consideration for replacement parts, as the pounds per square inch pressure output can range from 1500 pounds per square inch (PSI) on light-duty models to 3300 PSI on extra heavy-duty models as well as different output options in-between. The gallons per minute (GPM) water flow rates are also another consideration. The washer's horsepower may also affect the replacement parts, as the PSI and GPM amounts increase, the horsepower must increase as well to operate the unit.

To determine the necessary parts for their unit, homeowners should review the owner's manual or consult a professional to purchase compatible parts.
