Rated 3 out of 5 by Not a general purpose pump This pump is basically 5 centrifugal pumps in cascade, designed to lift water to a much higher point than any single-disc pump could manage. So, unless you want to do something like make a 100ft high fountain or lift water from a well to the tank in the attic of a four storey building (what I use mine for) - you might want to look at something else. Each impeller is necessarily small - so the overall flow rate is relatively low. Clearances are small - hence the water supply probably needs to be filtered/strained. I used a normal, self-priming, pump on a valved T inlet pipe to prime the system - removing that pump once the main pump is running. There must be a non-return valve in the inlet supply. I also have a pressure switch on the output pipe that must be closed (ie there must be a head of water on the output) for the pump to get power. That ensures that the pump will never run dry. Personally, I prefer the cast-iron pumps that these are replacing. Maybe not as efficient* but they would run for (almost) ever and take a lot of abuse. These won't. Run them dry, have a bit of sand in the water, let them freeze, or whatever and you need a new pump... *But they still use a LOT of electrical power. 21 Feb 2013
Rated 3 out of 5 by Okay We have an area of ground that fills up with water in heavy rain, so we pump it out. This only really happens a few times each year. The pump arrived and looks robust and well put together. I bought it with the recommended suction and delivery hoses as extras. A few comments. 1) It takes a bit of setting up. You have to fill the inlet (suction) hose with water, which is easier said than done, as they are already filled with air, obviously, and they have a non-return valve on the end. 2) You have to fill the body of the pump with water. This involves loosening drain plug and a bit of messing around. 3) you can't let it run dry, and it doesn't switch off when the pumping is complete, as there is no float switch. 4) All the water you put into it to make it work has to be drained back out before you store it, presumably to avoid freezing problems? All in all, it was a bit of pain to set up. I had an old dirty water pump that I connected an outflow hose to and dropped into the water, that just worked; this is quite different. If these problems won't cause you any difficulty, it looks like a solid pump at a reasonable price. The link to the manual didn't work when I bought this item - knowing the messing about involved in getting it to work each time, I would have bought something of a different design. 30 Aug 2012
