My Nilfisk specifically recommended not using the "waterstop" type hose
connector onto the pressure washer ...




I imagine that's just because of potential flow restriction, I can't see it
affecting the connector "grip".

To the OP, I'd just try a different hosepipe fitting, preferably without
the waterstop feature.

The problem with the waterstop is a spring loaded N/R valve.

Sorry Dave, but as I've explained, this is exactly what a waterstop valve
*isn't*.

My waterstop valves are neither spring loaded or non-return.

In normal use water flow will try to close the valve but if the hose is
connected to a male connector the male part holds the valve open. It cannot
close in this circumstance, even if suction is applied. It will introduce
some flow restriction though compared to a non-waterstop valve which is I
think the main reason for not using one with a pressure washer.
