Only 1gpm / 60 gph
on October 5, 2012
The output of the unit I received is only about a third of the advertised 185 gph. This is with about 1.5ft of vertical lift distance at the end of a 6 ft 3/8' I.D. vinyl hose.
There is a chart printed in the manual and on the outside of the box that provides the specifications of the various models of this pump. The numerical digits of the model numbers do not indicate the gph. The larger the number the more the capacity, but some models are spec'd at less than one might assume the model number indicates and some models are spec'd at more than the model number might imply. For example, this model, the ECO-185, is spec'd at 158 gph (although advertised at 185 gph) while the ECO-264 is spec'd at 290 gph.
It is spec'd at a maximun lift of 4.0 ft. At this height there was but a small drizzle of water coming out of the 6ft hose.
In any event you should probably buy a model that is spec'd quite a bit higher than your needs.
To test this unit I placed it on a ledge in my swimming pool about 1ft under water. Using a 3/8" I.D. vinyl hose I timed the filling of a 1 gallon milk jug at almost exactly one minute (1gpm, 60gph) with the jug sitting on the pool sidewalk. The maximum hose I.D. is 1/2". I was using 3/8" I.D. hose. With 1/2" I.D. hose I'm sure the output would be somewhat higher. I think the specs should state what the output should be with the various size adapters that are provide. Instead the specs only state the maximum that could be obtained under ideal conditions.
The pump was VERY quiet; I could not hear the pump at all above the ambient noise (normal outdoor noise level).
