Does a power washer have to have pressurized water on the inlet, or will it
draw from a tank source?

Most will draw from a tank, many older models do.

The big issue is making sure they get primed. Hence the tank needs to be
a bit higher than the pump.

A tank source higher than the pressure washer pump *is* a pressurized
source.

True but most folks dont consider .5psi to be "pressurized" but your
meaning is true indeed.

Most pressure washer pumps will not give you any reliable suction lift,
and can be damaged if they cavitate / run dry. As a general rule, if you
want to use water from a pond or the like, you will need to use a second
"charge" pump to get the water from the pond to the pressure washer. A
filter is also a good idea.


Very true.
