HI all,
I just thought I would add this
info to keep in mind if looking for a pressure washer...
Whether the motor/engine used on
a pressure washer ( PW ) is fueled by gasoline or electricity, it has
nothing to do with the power or PSI ( pounds per square inch) the unit puts
out. The horsepower of either a gas engine or electric
motor powered unit, combined with the type of pump and nozzle, and the
length of hose used is the determining factor on "power." Most
higher powered units also have a pressure control and relief valve on them to
avoid using too much pressure for the job.
I have three pressure washing
units, 600 PSI, 2,500 PSI, and 3,500 PSI, ( I find the 600# unit almost
worthless ) two electric and one gas, each using from 2 gallons of water
per minute to 4 gallons of water per minute. Two of them can be
turned down to a small and useless stream, or up to their maximum pressure and
volume as desired. Water supply, gallons per minute
(GPM) is a determining factor as to which unit can be used
where!
Gas engines are nice if you use
the machine in more than one location compared to electric units.
As not all electric outlets are the same...110V vs: 220V or
twist lock versus three prong, or a 220 with a 3 or 4 prong plug...welder type
plug, dryer type plug, range plugs... a lot of variables in electric
powered machines... gas engines will work most anywhere (keeping the
power unit OUTDOORS) as long as you have gasoline and a sufficient
water supply. Gallons per minute is a big deal! I recommend a
higher GPM pump, as more water does help in most cleaning
applications.
Something else to keep in
mind...electric units are a little quieter than the gas units... if
you use your PW in the city.
There are many different nozzles
available for many machines. Not all machines can use a variety of
nozzles. The nozzles are a determining factor in GPM and PSI.
There are nozzles that actually spin the water as it is propelled through them,
increasing the "power" by many times. If you have a very high volume PW
with high PSI, and you use one of these nozzles, it sounds like a swarm of
bumble bees with a bull horn! Wear ear and eye
protection!
I need more than one PW on our
farm, and have owned 4 and used several others over 30 years...my
recomendation is "do not" under power yourself...use
the pressure valve and set a more powerful machine at a lower pressure when
needed, that way you still have the higher pressure and volume if
needed for tougher and bigger jobs.

Cleaning whitewalls ??
Hi To All,
then hit the white walls
with an electric power spray if you own one.
Do not use gasoline power
sprays. They are too powerful.
