Description
K7 Unloader Description
The K7 unloader differs from traditional unloaders because it is a Flow Unloader rather than a Pressure Unloader. This means, inside the K7 Unloader is an orifice instead of a check valve to regulate flow.
A small channel in front of the orifice allows the increased pressure to travel up to the piston assembly, pushing it down. The rest of the water flow is diverted through the bypass and back to the float tank or pump inlet.
The K7 Unloader also differs from most pressure unloaders by not having a twist regulator on it. It is still able to be regulated via the nut and bolt at the point(although we don’t recommend doing this unless you have a pressure gauge on your machine.).
K7 Unloader Problems (Solved)
The most common K7 Unloader Problems cause low pressure or no pressure to be built at all after pulling the trigger. Whenever this happens check the following to ensure proper flow.
Proper Nozzle Size – With pressure unloaders, you may be able to put a smaller nozzle in to increase pressure and reduce flow. With K7 unloaders this is not possible due to restricting the flow and not building pressure after the unloader orifice.
Dirty Filer(s) – Having dirty inlet filters (filters before the pump on your pressure washer) can reduce the flow to a point where the water going into the pump is not enough to build pressure after the unloader orifice.
