I bought that little pump from Harbor Freight a couple years ago.
I live on a lake, and I use it to run my lawn sprinklers from the
water. During the spring and summer, it is in use 5-6 hours a day,
since it only draws about 6 amps and the water is free from the lake.
The pump is locate 10 feet above the lake level and the sprinkler
sysem is about 5 feet above the pump. Under these conditions,
the pump will run only one wide area sprinkler at a time, and
will pump about 4-5 gallons per minute..... If you don't have any
head on the input or output, you can improve on that some, but
it isn't really really great on putting out pressure --- good for
but not for cleaning. I just hook it to a sprinkler and go inside
drink beer and watch TV all day (retired...)
I have used mine for 2 years now, without a problem... It is NOT
self -priming, so you need to put a check valve on the intake and
fill up the suction line. Then you won't need to prime it again.
Be sure to take it inside in the winter because the water in the
pump housing will freeze and crack it.... However, they are very
I even bought a second one to use someday in the future when
the first one runs out......
