Considerations for Configuring Your Power Washer Setup
| Consideration | Why It Matters |
| Tasks (wash-down, interior cleaning, rinsing equipment, etc.) | Different tasks require different pressure (PSI), flow (GPM), hose reach, hot vs. cold water, etc. |
| Balance of pressure vs. flow | PSI = amount of cleaning pressure the machine produces / water force GPM = amount of water coming from the machine / rinsing power |
| Power source (gas vs. diesel vs. electric) | The power source needs to deliver enough horsepower to run the pump + any accessories, be durable & be readily serviceable |
| Pump type | Finding the right balance between performance and cost is important |
| Mounting/location on the truck | Placement impacts access, serviceability & wear and tear while on the road |
| Hose, reel & wand layout | The layout affects ease of use & performance |
| Hot vs. cold water | Hot = for more difficult cleaning jobs, but more expensive Cold = for standard cleaning jobs, but more affordable |
| Fresh water capacity | You need enough water available to complete tasks |
| Maintenance requirements | Keeping everything in good shape prevents downtime and saves money |
| Safety | Techs need to be safe when operating equipment & comply with any applicable safety standards |
