A pump leaking water indicates that there is something wrong such as bad water seals/packings or a broken ceramic plunger, or something minor like a leak o-ring. Any of these problems can be minor at first, but prolonged neglect can lead to bigger problems.
How Do I Tell If My Unloader Valve is Bad? In most occurrences, the first symptom of an unloader valve going bad is no pressure from the wand when the trigger is pressed. This happens when the unloader valve gets stuck open and does not allow water to enter the hose and trigger.
You could have a faulty lid or water level switch, or your hot and cold water supplies could be turned off or have kinks in the hoses. A clogged water inlet screen or a malfunctioning electronic control could also be the reason a washer isn`t filling with water.

They recommend 250 hours, but i’d change more often, like you said when it’s milky. If it begins to get water in the oil sooner, that indicates your piston to crankcase seal is beginning to leak.

I have a Northstar pressure washer powered by a honda GC160 engine. The last time i used it, water leaks from the bottom of the unit, whether it is running or not. When running, the pressure is fine. I have felt underneath and it appears that the water is coming from the second opening from the rear. Is there a pressure relief valve there. I have a manual but cannot find any descriptors for underneath the motor.
