Mini Karcher Pump
20 Dec 2012
By Tomo6r4
, Oxfordshire
"I've had this little pump dropped into a failed septic tank for over a year now.
Every time it rains (which seems to be every bloody day at the minute) the Karcher kicks in on the float switch and keeps the level right in the tank.
I have been chuffed to bits with it. I pull it out every now and again to check it, and it's black with grunge. Poor little thing. Still pumping well though.
It's not going to keep the River Avon at bay, however I can definitely recommend this pump for low volume gentle pumping."

A good little pump
5 Oct 2012
By Focaldepth
, North East
"I have had one for a few years and have used it mainly for emptying a Koi pond. Allso used on muddy water at times. Just chugs away and does it's job. The float switch is fiddly to get the last 6" of water but all pumps in this class are the same."

"bought this to replace a burnt out pump in a customers basement, it is very quiet and works well. the lead attached is very long which is unusual these days. Who knows on reliability but hopefully being Karcher it should be ok"

Perfect for the job

By Tiny

"I purchased this pump to clear constantly flooding footings during February this year
the pump worked very well with dirty muddy water and had no trouble lifting 2 meters with a very rapid delivery rate.
I can fully recommend this for anybody looking at similar tasks

Karcher Dirty Water Pump
7 Jun 2010
By jellybean
, Taunton
"I bought this item to pump water from a well, to be used to water plants, especially if we have a hose pipe ban.
The depth of the well is nearly 3 metres and the pump lifts the water easily to the top. It seems well made and hopefully will be reliable. One criticism is that you are not advised when buying the pump that if you want to connect to a garden hose then you need the Karcher adaptor and this is extra. Also the adaptor will only fit a 3/4 inch hose and not a standard 1/2 inch garden hose. Be warned."

Not the Best
23 Nov 2012
By Karlynns
, Nottingham
"Not what you would expect from Karcher.
The pump has an automatic float cut of switch that cuts off the machine far to early.
In my example i had a bath full of water and a blocked saniflow, the pump cut out when i still had 10" of water in the bath so rather pointless. I had to tie up the automatic cut off.
You also have to be careful not to get an air lock as the small pump cannot deal with it and you get a lot of noise and little action"
