Reflux valves

Installation of reflux valves.

A reflux valve allows sewage to flow in one direction only and is intended to automatically close when flow reverses.

Reflux valves are installed in the property sanitary drain, usually at properties that do not have an overflow relief gully (ORG) installed, however some properties may have both. A reflux valve may also be required for a property in a flood zone.

When a reflux valve is fitted, a property owner enters into an agreement with the Corporation which details installation and maintenance responsibilities.
