Used Commercial Pressure Washer Inspection Guide
Whether a used machine starts tells you almost nothing. Here is how to find out if the pump, burner, engine, plumbing and safety controls will hold up under a real day of work.
Three running categories. Repair and diagnosis, job playbooks, and honest equipment comparisons — all of it from machines that actually came through our shop.
Whether a used machine starts tells you almost nothing. Here is how to find out if the pump, burner, engine, plumbing and safety controls will hold up under a real day of work.
A skid should make your crew faster on the jobs that pay the bills, not just look organized in the back of a truck. Here is how to plan one around the work, the water and the wrench.
A dairy barn stays clean because the machine moves enough water, handles the soil load, applies chemistry correctly, and is ready to run when the washdown window opens. Here is how to size one for the job.
A fleet can look washed and still carry the gray road film that makes trucks look neglected by the next stop. Choosing detergent means matching the soil, the surface, the wash method, the water temperature, and the equipment supplying it.
A hot-water machine that makes pressure but no heat is costing you on every job. Find out whether the coil is really the failure, what caused it, and whether repair protects uptime better than replacement.
A pump rebuild can put a commercial machine back to work, but it is not automatically the right answer. The real question is whether the pump has a sound foundation and whether the repair protects more revenue than it costs.
A hot-water machine that makes pressure but delivers cold water costs you on every job. Separate a true burner failure from a water-flow, fuel, or safety-control problem before you buy a single part.
A machine can show impressive PSI on a spec sheet and still be the wrong tool for the work. Start with the soil, the surface, the production target and the water supply.
Buy the wrong setup and the cost shows up in slow production, damaged surfaces, wasted fuel, and repair bills. Start with the job, not the catalog.
A machine that runs fine but won't make pressure is the single most common call we get, and it is almost never the pump.
Most people shopping for more pressure are short on flow and do not know it yet.
Winter fleet work is good business precisely because it is inconvenient. Here is how to do it without destroying equipment.
Two cheap parts that get confused constantly — and confusing them is how people end up replacing the wrong one twice.
The format decision you live with every day for five years, and the tradeoffs nobody mentions at purchase.
Agricultural washdown is non-discretionary spend — the parlor gets cleaned whether or not it has been a good year.
Cold-weather burner failures follow a predictable order, and the answer is usually near the top of it.
Rust removal is a chemistry problem. Solve it with pressure and you will leave a bright etched patch that looks worse than the stain did.
We publish this list because you should be able to run it on any machine you are considering — from us or from anyone else.
