Pressure’s On! How to Keep Your Pressure Washer from Failing When You Need It Most
June in the Kansas City area is the prime time for "outdoor cleanup." Whether you’re prepping the deck for a Father’s Day BBQ, washing away the spring pollen from your siding, or cleaning up the driveway in Lee’s Summit, your pressure washer is your best friend.
However, pressure washers are unique machines. Unlike a lawn mower, which might just run poorly if neglected, a pressure washer can actually destroy itself if it isn’t maintained correctly. At Atlas Mobile Small Engine Repair, we see a surge of pump failures every June. Here is how to keep your machine under pressure and out of the scrap heap.
The Silent Killer: Pump Cavitation and Heat
The engine is only half the story. The pump is the heart of a pressure washer, and it’s surprisingly fragile. Here are the two biggest mistakes we see:
Running "Dry": Never start your engine without the water turned on and flowing through the pump. Running a pump without water for even 30 seconds can melt the internal seals.
The "Idle" Trap: If you leave your engine running but aren't actually pulling the trigger to spray water, the water trapped inside the pump starts to circulate and heat up. Within minutes, it can get hot enough to warp the pump’s internal components. If you aren't spraying for more than two minutes, turn the engine off!
Atlas Pro Recommendation: Engines vs. Pumps
When you’re looking to buy a new pressure washer, the pros at Atlas look at two things: the engine brand and the pump type.
The Best Engine: Look for a Honda GC or GX series engine. They are remarkably easy to start and can handle the high-vibration environment of a pressure washer.
The Best Pump: If you want a machine that lasts a decade, look for a Triplex Plunger Pump (found on brands like Simpson or Mi-T-M). They are more expensive than the "Axial" pumps found on budget models, but they are fully rebuildable and much more durable.
The Atlas June Maintenance Check
Is your pressure washer pulsing, leaking, or losing power? Our mobile service covers both the "go" (engine) and the "flow" (pump). When we visit your home, we check:
Pump Oil: Yes, many high-end pumps have their own oil that needs changing!
Unloader Valve: We adjust the valve that controls the pressure to ensure you aren't damaging your surfaces or your engine.
Thermal Relief Valve: We ensure this safety feature is working so your pump doesn't overheat.
Engine Tune-Up: New spark plug and air filter to handle the dusty June conditions.
Don’t Let a Clogged Nozzle Stop Your Progress
Before you call us, check your spray tip! A tiny grain of sand in the nozzle can make it feel like your pump is dying. If that doesn't fix it, give us a call. We bring the repair shop to your driveway so you can get back to making your home shine.
