Great price for a great name! The cheapest I can find this elsewhere is Amazon for £33.76, and Argos £44.99.
This Hozelock 3-in-1 water butt pump comes complete with self priming, high pressure pump with 1.1 bar. It enables stored water use in the garden with a hose gun, sprinklers, and micro irrigation products. The water butt pump has a 10m power cable and includes an easy clean filter.
Obviously it can be used for other things as well.
