Good pump, which unfortunately also has small weaknesses.

From the processing of the pump I am pleasantly surprised.
It is light and very handy.
The running noise, I would rather be regarded as low, compared with other known brand manufacturers,
which are much more expensive plus manufactured in plastic housing.

The most important aspect of this pump is that the pump impeller housing fully
is filled with water.
There must be no air bubbles form, which applies to the entire intake path, including non-return valve.
Any small leak in the suction line causes no pressure is being built.

These weaknesses show from my experience, too much expensive brands.

My 34 years old "Siemens garden pump" does not have these drawbacks.
This also builds on small leaks on their pressure.
Too bad, unfortunately this quality bearings in oil pump will no longer be built.

Despite the flaws, I am very satisfied with the pump,
as it also is still very quiet operating noise.

I can not even about the life of the pump say much because they only
For a few days in operation.
