Rated 4 out of 5 by Karcher 450W Dirty Water pump Looks well made, and worked as soon as installed yesterday, although water seen to be coming out of de-aerating button at top - not sure if this is normal. If it continues to work as now, will be well satisfied. 12 Sep 2014
Rated 4 out of 5 by Seems a substantial product. Have been using this for a couple of days now for pumping water out of foundation trenches, works quite well and takes the water down to around an inch, Cannot really assess its long term reliability as only run it for about 2 hours in total. 28 Jul 2014
Rated 4 out of 5 by Good Pump ! For the price this is a good buy. I particularly liked the outlet at the top. Most pumps seem to have the outlet at the side. I would have liked a central handle from which to hang it in the sump. It worked really well when required for three months then seems to have developed a fault which caused the power to trip when submersed, so I have had to throw it away. I may have expected too much from it, pumping dirty water from a farmyard. I have replaced it with a much more powerful pump with overload protection. For light use as described by Screwfix, I think this is a good pump. 20 Mar 2008
Rated 5 out of 5 by Just in case In the summer floods of 2007 I had 42" of water in my cellar and my pump burnt out. I brought this Karcher as a replacement and when the water returned in February this year it worked wonderfully well. It dealt with large amounts of dirty water and was very reliabile. 6 Mar 2008
