Where it is used
In basement areas, or where pipes pass through external walls below the water table or in flood-liable locations, a puddle flange helps keep water out along the pipe run. Denso tape or similar should be wrapped around the pipe before the two-piece flange is bolted on, to achieve a watertight seal.

Ground movement
Cast iron expands by around 0.01mm per metre for every degree Celsius rise in temperature, a coefficient close to that of concrete and steel. In practice this means a buried Halifax run moves very little relative to the ground around it, unlike some plastic systems where thermal expansion can be five to twenty times greater.
