This additional pump unit enables two water containers to be used simultaenously, so that even more rainwater can be used for irrigation. The pump unit can be installed quickly and easily in any desired location: it draws its power from the main pump, meaning that you don't have to provide an additional power source. The pump extension kit is compatible with the Bosch GARDENPUMP 18 and the GARDENPUMP 18V-2000 (it may also be suitable for subsequent models released after this list was compiled).
