Tips for Keeping Jetting Equipment in Top Condition
High-pressure jetting rigs cost more to replace than to maintain. A disciplined daily routine keeps pumps, hoses, and nozzles ready for the next job instead of the repair shop.
Clean water is the cheapest insurance policy you can buy. A 30-second tank check prevents grit from becoming expensive pump scarring.
Start Every Shift With a Three-Minute Inspection
Check Oil Before You Check Pressure
Pull the dipstick while the engine is cold. Milky streaks mean water is sneaking past seals and diluting lubrication.
Top up to the upper mark with the grade the maker lists. Running even a pint low accelerates bearing wear.
Feel Hoses for Soft Spots
Squeeze every metre of hose between thumb and forefinger. A spongy section is a blister waiting to burst under full load.
Twist the hose slightly; cracks open widest under torsion. Replace any line that reveals cord.
Spin Nozzles By Hand
A nozzle that grinds instead of gliding has picked up sand or rust. Flush it clear before it scores the ceramic seat beyond repair.
Filter Tactics That Save Pumps
Stage Screens in Series
Drop a coarse basket in the tank first, then a 40-mesh inline, and finish with a 100-mesh at the pump inlet. Each trap catches a different particle size so nothing reaches the plungers.
Clean Screens Without Tools
Back-flush filters with the rig’s own pressure instead of stabbing them with screwdrivers. A five-second blast dislodges silt without tearing mesh.
Label Spares for Speed
Store backup filters in zip bags marked with mesh size. A labeled stash lets anyone on the crew swap elements in seconds.
Hose Handling That Prevents Kinks
Deploy in a Straight Line First
Uncoil the full length on open ground before dragging it around corners. Pre-straightening removes memory kinks that choke flow.
Use Wide Arcs at Corners
A 90-degree bend tighter than 300 mm radius pinches the inner tube and drops pressure. Place a rounded guard or wheel at every sharp turn.
Flush Before You Reel
Run clean water for ten seconds after the job ends. This pushes abrasive slurry out so it can’t dry and crack the inner wall overnight.
Nozzle Care Beyond the Obvious
Store Each Size Separately
Mixing nozzles in one box leads to cross-threading and lost orifices. Keep each size in its own labeled tube or magnet strip.
Polish Seats With Toothpaste
A pea-sized dab of plain white toothpaste on a cotton swab lifts mineral film from ceramic seats without scratching. Rinse thoroughly before reuse.
Rotate Orifices Weekly
Swap front jet nozzles with rear ones to even out erosion. Even wear doubles the usable life of a full set.
Winterization Without Antifreeze Mess
Blow Lines Dry With Shop Air
Connect a blower nozzle to the hose end and open the trigger until only mist exits. Dry tubes won’t split when leftover water freezes.
Pull Plunger Pumps Apart
Remove the inlet manifold and tilt the pump until water drains from each cylinder. A single trapped drop can crack a sleeve.
Grease Fittings Last
Hit every zerk after draining so fresh grease displaces surface moisture. Grease acts like a blanket against condensation all winter.
Coupling Care That Stops Micro Leaks
Tighten With Two Wrenches
Hold the female side steady while you turn the male. Single-wrench tightening twists the hose and loosens again under vibration.
Replace O-Rings at First Flat Spot
A ring that has lost its round profile will weep at 2,000 psi. Keep a strip of assorted sizes in the glovebox for field swaps.
Lubricate Threads Graphite-Dry
A swipe of graphite stick keeps threads smooth without attracting grit like oil does. Dry lube means cleaner hands and tighter seals.
Pressure Gauge Habits That Catch Cavitation
Log Baseline Every Monday
Note the gauge reading at full rpm with a clean nozzle. A 5% drop a week later signals worn valves or sucking air.
Isolate Gauge When Not Needed
Install a mini ball valve between pump and gauge. Closing it when you throttle down shields the delicate bourdon tube from pulsation fatigue.
Vent Mount Away From Vibration
Move the gauge off the pump head and onto a short pigtail of hose. Dampening extends life and keeps the needle steady enough to read.
Engine Side Often Ignored
Cooling Fins Are Radiators
Blow compressed air backward through the shroud to eject grass and oil film. Blocked fins raise coolant temperature and thin the oil that lubricates the pump.
Fuel Stabilizer Every Fill
Modern ethanol blends attract water that corrodes carb jets. A dash of stabilizer keeps the fuel phase uniform and the engine starting first pull.
Check Belts for Glaze
Shiny belt sides indicate slipping. Scuff the pulley grooves lightly with emery cloth to restore grip before the belt burns through.
Post-Job Cool-Down Routine
Idle Down for Thirty Seconds
Let the pump drop from full pressure to idle before shutting off. This bleeds heat from the head and prevents coolant boil-over.
Crack the Trigger First
Open the gun while the engine idles so trapped pressure escapes through the hose, not past the unloaders. Softer valve seating means longer seat life.
Wipe the Rig Dry
A quick towel pass removes chemical film that attracts dust. Dry metal surfaces let you spot fresh leaks at a glance next morning.
Training the Crew to Own the Gear
Assign One Check Per Person
Give each operator a single daily item—oil, belts, or leaks. Shared checklists prevent “I thought you did it” failures.
Take Phone Photos of Wear
A dated picture of a fraying belt or weeping seal shows progression better than memory. Images settle disputes about when to replace.
Reward Spotless Rigs
Buy lunch for the team when the unit scores a zero-drip inspection. Pride keeps standards higher than any manual can.
