    Unloaders &
    Injectors

    Unloader valves and chemical injectors for commercial pressure washers, shipped nationwide. Trapped-pressure and flow-actuated unloaders. Downstream and upstream injectors. The unloader routes flow back to the pump when the trigger closes — a failed one either spikes pressure or won’t build it at all, and both get misdiagnosed as a bad pump. Sizing depends on your GPM and pressure rating. Send your specs and we’ll confirm the right one.
