Types of devices

- high hazard – any conditions, device or practice which in connection with the water supply systems has the potential to cause death.
- medium hazard – any condition, device or practice which in connection with the water supply could endanger health.
- low hazard – any condition, device or practice which in connection with the water supply system would constitute a nuisance but not endanger health.
