Embedding the Tank 1) Excavate to the appropriate dimensions, allowing for a 150 mm bed of sand at the base. 2) Lower the tank carefully into the excavation onto the sand base. 3) Fill the tank 2⁄3 with water, then backfill around the tank with sand in layers of 30 cm and compact each layer by hand. Ensure the tank is evenly hand compacted on all sides. 4) Fill the tank with water to the overflow level and continue to back fill with sand and hand compact to the overflow level. 5) Make the push fit connections with 110 mm watertight pipework. The service duct should be run to the surface connection point, with a pull through cord left in. 6) Place the tank access cover onto the tank. 7) Fill the excavation to finished levels with topsoil. 8) Leave the water in the tank until installing the pump. StormBank® Garden User Manual Topsoil Fill with Water Prior to Backfill Backfill with Sand in 300 mm Steps, Hand Compacted 150 mm Sand Base Note: A) In heavy clay soils, rainfall might permeate around the installation, but not drain away through the surrounding earth. This can collect below the tank and could cause buoyancy, particularly if the tank is left empty. In poor soil it is recommended that a concrete base is formed, with straps used to permanently hold the tank. Please contact Hydro for further information. B) Any downpipes from the roof should run directly into the ground, without using a grille or gully, as these could allow grit and debris to be swept into the StormBank® tank. Paved and concreted areas should be drained separately to the roof - water from these areas is not suitable for your StormBank® system. StormBank® Garden Installing the Pump 1) Using PTFE tape, screw in the larger 1”- 20 mm hose insert to the threaded hole on top of the pump. 2) Screw the plastic inlet filter on to the end of the pump. 3) the lifting rope supplied through the handle on top of the pump.
