Commissioning Procedures

Check that surface water does not flow in the H₂grO. Visually check the H₂grO is surrounded by a graded concrete path / paving or alternatively, that the top of the unit is 75mm above ground.
Make a water seal in the 100mm DWV trap to prevent release of odours from the sewer drain. If necessary, fill the trap with water from a tap.
Confirm that the greywater discharges onto the filter screen. Observe the flow of greywater passing through the filter screen.
Check the electrician has completed and checked the wiring.
Check garden outlet plumbing is connected. If installing the irrigation system at a later date fit a hose to each outlet and direct the flow back into the H₂grO.
Activate the electrical mains supply to the H₂grO.
