Pressure Wash Dump Guns for Industrial Cleaning and Car Wash systems Safety Jet ? Dump Guns are premium heavy-duty dump guns designed to reroute the flow of water at the gun avoiding pressure spikes and high-pressure re-circulation, which can cause overheating of the pump, resulting in system failure. Safety Jet ? Dump Guns use a double-barrel design to divert the flow of water around the pressure nozzle to the dump barrel. This reduces the pressure of outflow rather than stopping it, avoiding the need for an unloader valve. This design also allows the dump gun to be used on weep systems.
