It simply needs to have water available for the suction side to be able

Its not rocket science..its simply a pump that has some suction. GPM on
the average high pressure pump is quite low, hence

As is so often the case, you don't have a clue. Some pressure washers
such as the CAT models that used an intake tank should be OK with
modest suction lift. But most modern consumer-grade models probably
aren't. Both of mine will fail to leave unloaded-mode if the pressure
intake is restricted very much. Which is probably one of the reasons
that most owner's manuals I've seen specifically warn against going
below about 20 psi on the intake side. But what do they know compared
to the Taft oracle?

they really dont need a lot of water to spray properly.

Oh really? One of mine is the popular 13hp 4.5 gpm types. Why don't
you show us how to calculate the suction specs for that?

Ever thought of not commenting when you when you haven't anything
useful to say? Of course not.
