Pressure Washer Attachments FAQ's
How do I stop leaks at couplers?
Replace worn O‑rings, confirm matching coupler sizes, and remove grit from the fittings. A small O‑ring kit in your toolbox makes quick fixes easy on the job.
What quick‑connect size do I need?
Spray tips typically use 1/4 in. quick‑connects. Hoses and many pro accessories commonly use 3/8 in. quick‑connects or M22 threads at the gun and hose—verify each connection before ordering.
Do foam cannons work with any pressure washer?
They work best when the orifice matches your machine’s GPM. If foam is thin, check dilution, clean the filter, and use a smaller or larger orifice as recommended by the manufacturer.
Why won’t my surface cleaner spin or why is it leaving stripes?
Common causes are incorrect nozzle sizing, inadequate GPM, a clogged nozzle, or a worn/under‑lubricated swivel. Verify orifices, clean the bar, and service the swivel per the manual.
Which spray tip should I use for most cleaning?
Many users rely on 25° or 40° tips for general cleaning and rinsing, moving to 15° or a turbo nozzle only for tougher deposits on hard surfaces. Always test in a small area first.
How do I know if a pressure washer attachment will fit my machine?
Check four things: the attachment’s max PSI, GPM and temperature ratings, plus the connection type (1/4 in. quick‑connect, 3/8 in. quick‑connect, or M22 threads). All four must meet or exceed your machine’s specs and match your fittings.
