This 2″ puddle pump suitable for clean water pumping down to 1mm. Complete with internal check valve and has to be primed if using in shallow water e.g. puddles. Comes complete with 10 metres of power cable, hose tail, hose clip and 5 metres of rope, this pump is designed so that the delivery flange can be altered from vertical to horizontal. (To stop that annoying kink in the hose).
