Rated 3 out of 5 by from Fittings not supplier The float switch is a little hit and miss as it doesn't activate the pump at a consistent height of water, My real gripe, however, is that it comes with a threaded outlet, but not the fittings to attach this to a hose. Unlike most pumps (even other Karcher pumps) you have to buy this separately. For the sake of a few pence worth of plastic, it should be included.

Rated 5 out of 5 by from KARCHER SP3 350W It is a great pump...I have noticed the buoy will not trigger the pump to kick in. You have to basically tie it up vertically then the pump starts up.

What level distance can this pump to? Would 32mm hose give less resistance?

Asked by: LesCM19
Hello LesCM19, Unfortunately there are too many factors to advise the distance it can pump to. The hose needs to be. A 32mm/ 1 1/4" hose should be used with this machine. Karcher UK

buoy will not trigger the pump to kick unless tied up vertically?

Someone on the reviews stated issue with buoy will not trigger the pump to kick in. You have to basically tie it up vertically then the pump starts up. Is this a fundamental issue?
Asked by: abilo
Hello abilo. The Karcher SP3 Pump has an automatic mode which will activate when the float switch senses water however if the machine is in manual mode then the float switch is not required - Kärcher UK

Variable speed?

I intend to use two of these in two 1000ltr water butts to water the garden, if I connect them via a dimmer switch will I be able to control the speed at which the pump runs to reduce the flow rate. The hose I’ll be using is in excess of 30M long.
Asked by: Jimsajaffa
Hello Jimsajaffa. Unfortunately the SP3 pump does not have an adjustable flow rate and is also not suitable for continuous use - Kärcher UK

Does this pump have a non-return valve built into it, or do I need to include one within the discharge pipework?
