Why a Diesel Pressure Washer Matters—for Households and Fire Crews
Picture this: branches and debris everywhere after strong winds, mud and grime on the patio, or gutters full of leaf litter right before fire season. For fire crews, it’s about removing oily soot, prepping vehicles, and getting vital gear clean fast after a long shift.
The Crommelins Yanmar 3000PSI isn’t just a workhorse for tradies or rural properties. It’s the same tough unit trusted by professionals on the frontline—diesel-powered, robust, and built for Australia’s harshest conditions. And because it runs on diesel, you don’t have to worry about electrical leads, petrol storage, or running out of power far from the house or shed.
Who benefits most?
Households: Fast, deep cleaning for driveways, walls, roofs, and decks. Removes mud, algae, and that build-up you keep ignoring.
Rural properties: Perfect for prepping sheds, farm gear, and water tanks, or cleaning up after storms and grass fires.
Firefighters & Crews: Washes away oily residue, smoke stains, and ash from appliances and trucks. Cuts cleaning time, helps keep gear safe and reliable.
What Makes the Crommelins Yanmar 3000PSI Stand Out?
If you’ve ever tried to shift baked-on dirt, old gum leaves, or smoke stains with a garden hose, you know it’s a losing battle. That’s where the Crommelins Yanmar’s 3000PSI (pounds per square inch) pressure comes in. Here’s what you’re really getting:
Serious Cleaning Power:
3000PSI is enough to lift thick mud, paint flakes, oil, and even moss—without spending all day on the job.

Real story: After a week of mop-up work on a bushfire, we once tried cleaning the truck and hoses with a little 240V electric washer. Took us hours and left streaks. Swapped to a diesel like the Crommelins—done in half the time, and everyone had clean kit for the next job.
How to Prepare: Setup, Safety, and Smart Planning
You don’t need to be a mechanic or an old hand to get this washer running. But like all powerful gear, it pays to prep and plan ahead—especially if you’re new to diesel or tackling a big clean-up for the first time.
At Home:
- Choose a safe, flat spot for setup—away from pets, kids, or anything fragile.
- Fill with clean diesel (never petrol!). Check oil and water levels before every use.
- Use the correct nozzle for each job—narrow for grime, wider for gentle rinse.
- Keep all connections tight, and run the hose out straight to avoid kinks.
On the Fireground:
- Check your crew’s diesel supply—pressure washers use less than a truck, but still need planning on multi-day jobs.
- Assign someone to keep watch during use—flying debris and water spray are real hazards when tired.
- Wear eye protection and gloves. Safety boots are a must, not a maybe.
- Plan your cleaning order: dirty appliances and gear first, then the truck and hoses.
Common mistake: Forgetting to bleed air from the pump after running out of water can burn out your unit. Always check supply lines before starting.
Pressure Washer Safety: Keep Yourself and Others Safe
A 3000PSI diesel pressure washer is not a toy—it’s powerful enough to break skin or crack tiles if used carelessly. Safety is simple, but easy to skip when you’re tired, stressed, or rushing. Here’s what works:
Always:
- Check all hoses and couplings for leaks before starting.
- Start at low pressure, then ramp up—never blast at full power first go.
- Point the nozzle away from yourself and others before turning on.
- Wear eye, hand, and hearing protection.
Never:
- Let kids or untrained people operate the washer unattended.
- Use the washer on ladders or unstable surfaces.
- Point the spray at people, animals, or electrical equipment.
- Store the washer with water left in the pump during winter—this can crack the housing.
Fireground tip: When tired after a long shift, always buddy up—one cleans, the other watches for hazards and keeps the area safe.
Packing, Maintenance, and Storage—Longevity Matters
Diesel gear can last a decade or more if treated right. But we’ve all seen old washers rusted solid after a wet season, or ruined because no one drained the pump before winter. Here’s how to keep your Crommelins running strong:
Before storing:
- Run clean water through the pump after every use—removes mud, grit, and chemicals.
- Drain all hoses and the pump, especially before frost or long storage.
- Check all seals and bolts—tighten if loose.
- Wipe down with an oily rag to prevent surface rust.
For fire crews:
- Store fuel and washer separately in your shed or station—label clearly for emergencies.
- Assign a gear officer for regular checks after each deployment.
- Keep a simple logbook: date, who used it, and any faults or breakages.
Lesson learned: Most breakdowns come from skipping basic care, not from the machine itself. Even one missed flush can lead to pump corrosion—costly and annoying.
How to Use in an Emergency: Storms, Fires, Floods
Emergencies don’t just test your patience—they push your gear to the limit. We’ve all seen it: after a bushfire, ash and soot everywhere; after a storm, piles of mud, leaf litter, and even sewage on paths and driveways. A diesel pressure washer is often the fastest, safest way to clear up and get back to normal.
Home example: “After the 2020 fires, our family’s roof and gutters were coated in fine ash. We used a pressure washer to clean every inch—felt safer knowing the house was ready for next season.”
Fire crew example: “We finished a 16-hour shift during the big grassfires. Our boots, hoses, and even the truck cabs were caked in black. The crew’s diesel washer did the work of five brooms—everyone’s gear was ready for the next callout.”
Don’t forget: Always check local rules before cleaning off chemicals, fuel spills, or sewage—runoff can damage creeks or drains. Use proper containment where possible.

Q: Is diesel safe to store at home?
A: Diesel is safer than petrol—less flammable and easier to handle. Store in labelled, sealed containers, away from heat, kids, and pets. Never inside your home; use a shed or outdoor storage spot.

Q: What if I have a water tank or limited supply?
A: You can use tank water, but always fit a filter to the inlet hose. This stops grit damaging the pump. Monitor your water levels—pressure washers use more water than most people expect.

Q: How do fire crews manage cleaning on long deployments?
A: Most bring their own diesel washer (like this one) and a water trailer. Crews share jobs—one team cleans, another does maintenance, and a third keeps track of fuel and faults. It’s all about teamwork and a routine after every shift.

Q: Are these washers worth the investment for ordinary homes?
A: If you deal with regular storms, bushfire ash, or have large outdoor spaces, a quality diesel washer will pay for itself over the years. It’s a big outlay but saves time, effort, and future repair costs. For light cleaning, consider a smaller unit—but if you need true power, this is the way to go.
