Hi Tech support,
I have a KARCHER 620M and it will not draw water from a tank or a bucket..
I have replaced the head and changed all the filters and made sure all the valves were woking well. It did not draw water from day one since new but it works under tap pressure.

When my 620M is connected to main water supply and motor on it sounds ok but when trigger pulled the water pressure drops significantly. What can cause this?
