It is a practical upgrade for truck wash crews, mobile detailers, fleet wash operations, and serious home setups that need to move from soap application to rinsing without stopping to change a complete lance.\u003c\/div\u003e\n\u003ch3\u003e\n\u003cbr\u003eWhy You Need The Hi-Lo Trombone Valve.\u003cbr\u003e\n\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSwitch between a high-pressure rinse tip and low-pressure soap tip without breaking up your wash process\u003c\/li\u003e\n\u003cli\u003eSave time on fleets, semis, RVs, pickups, trailers, and equipment where every extra tool change adds up\u003c\/li\u003e\n\u003cli\u003eKeep your pressure washer wand setup simpler than carrying a separate dual-lance assembly\u003c\/li\u003e\n\u003cli\u003eApply truck wash soap through your downstream injector, then move directly into high-pressure rinsing\u003c\/li\u003e\n\u003cli\u003eReduce interruptions for mobile detailing crews working from a trailer, van, or wash skid\u003c\/li\u003e\n\u003cli\u003eBuild a more efficient soap-and-rinse setup for touchless truck wash and foam cannon workflows\u003c\/li\u003e\n\u003cli\u003eKeep the right nozzle ready at the gun instead of setting tips down in wet, dirty wash areas\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat Makes The Hi-Lo Trombone Valve Different?\u003c\/h3\u003e\n\u003cdiv\u003e\n\u003cbr\u003eThis Hi-Lo trombone valve is a compact nozzle holder with two working positions: one for high-pressure washing and one for low-pressure chemical application. Instead of removing and reinstalling spray tips every time you change tasks, the valve lets the operator shift between the two modes at the wand.\u003cbr\u003eIt replaces the repeated nozzle swapping that slows down a normal pressure washer setup. For truck wash and fleet work, that means less downtime between pre-soak, soap application, and final rinse.\u003c\/div\u003e\n\u003ch3\u003e\n\u003cbr\u003eRecommended Pressure Washer Routine\u003cbr\u003e\n\u003c\/h3\u003e\n\u003col\u003e\n\u003cli\u003eShut off the pressure washer, release all trapped pressure, and disconnect the water supply before installing or servicing the valve.\u003c\/li\u003e\n\u003cli\u003eConfirm that the valve, spray gun, lance, fittings, hoses, nozzles, and pressure washer are compatible with one another before use.\u003c\/li\u003e\n\u003cli\u003eInstall the valve using the two 1\/4-inch NPT female connections and seal threaded fittings correctly.\u003c\/li\u003e\n\u003cli\u003eInstall a properly sized high-pressure rinse nozzle in one position and a low-pressure soap nozzle in the other.\u003c\/li\u003e\n\u003cli\u003eStart with the low-pressure setting to apply your compatible truck wash soap through a downstream injector or chemical system.\u003c\/li\u003e\n\u003cli\u003eAllow the wash chemical to work according to its product label, and do not allow chemical to dry on the vehicle.\u003c\/li\u003e\n\u003cli\u003eShift to the high-pressure setting and rinse thoroughly from the top down.\u003c\/li\u003e\n\u003cli\u003eNever point the wand at people, animals, electrical components, or delicate vehicle surfaces; always follow the pressure washer manufacturer’s operating and safety instructions.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003ch3\u003eEquipment \u0026amp; Setup Recommendations\u003c\/h3\u003e\n\u003cdiv\u003e\n\u003cbr\u003eThe Hi-Lo Trombone Valve works best as part of a properly matched pressure washer soap system.
