Guns FAQ's
Why does my gun leak from the front or feel weak after months of use?
Seats, seals, and O‑rings wear over time—especially with abrasive water or heat. Replace the repair kit and verify your nozzle size and unloader setting afterward.
What is a weep gun and when would I want one?
A weep gun allows a small flow to pass when the trigger is released. This can help reduce freeze risk and pressure spikes in cold climates or stop‑and‑go work.
When should I choose a short “stubby” gun?
Pick a short gun for close-up control around vehicles, tight spaces, or when using foam cannons and short lances. Use longer assemblies when you need more reach.
What’s the benefit of an easy-pull or relaxed-action trigger?
It reduces the hand force required to keep the trigger open, which lowers operator fatigue during long jobs without changing the machine’s output.
Can I use a hot-water machine with any gun?
No. Check the gun’s temperature rating and match it to your heater output. Many pro guns are rated near 300°F, while others are limited to about 200–212°F.
What inlet and outlet sizes are most common on professional pressure washer guns?
Most pro guns use a 3/8″ FNPT inlet for the hose and a 1/4″ FNPT outlet to the wand/nozzle. Many setups then step to 3/8″ quick connect on the hose side and 1/4″ quick connect on the nozzle side.
