Using pallet wood, rather than buy a cage, I built a frame for the water butt. Without the frame, the water butt turned into football and because the base was not level, rolled off and emptied itself. My first job was to level the base. The pallets were placed onto to blocks and level.
The frames were held together with corner brackets and screws, used an angle grinder to smooth off the protruding screws. Vertical timbers kept the hoops in position and it was filled to about half. The tap ordered on ebay, arrived and was fitted on the IBC tank. I’ll let the chlorine dissipate overnight. It will make watering the poly tunnel so much easier.
