Rodding points may be located at the head of a drain or in an intermediate position. Since it is not possible to remove debris from a rodding point, access must be provided at a point downstream. Rodding points should not be used on drains deeper than 2 metres.
As long as the point is imbedded in concrete, it can be used in situations accessible to light motor vehicles. If positioned in gardens, it is recommended that the surround is paved or concreted to prevent the cover from becoming concealed by grass or soil.
