The fill/drain nipple (11DV) of the potable water service panel has an
electrical heater to prevent ice.
The heating element is energized when electrical power is applied to the
aircraft.
H. Potable Water Ice-Protection (Ref. 30-73-00)
The waste water from the galley and lavatory washbasins is moved to the
related drain mast through water lines. To prevent ice, in or around the
water lines, they have electrical heaters.
The heater assemblies are temperature controlled.

F. Waste Water Ice Protection (Ref. 30-71-00)
(Ref. Fig. 014A)
The waste water from the galley and lavatory washbasins is discarded overboard through three drain masts (4DU, 14DU and 24DU) on the bottom skin of the fuselage. To prevent ice, in or around the drain masts, they have electrical heaters.
The drain masts have internal electrical heat-elements, which are connected to the aircraft electrical network. The elements are energized when electrical power is applied to the aircraft. There are two power levels for the drain masts, 18.72 Watt (on the ground) and 313.6 Watt (in flight).

A visual icing indicator is installed on the the center pane retainer
between the two windscreens. It can be seen by the two pilots.
R **ON A/C 401-499,
R An advisory ice detection system is installed, which operates during all
R flight phases. It has two ice detectors, but only one detector is
R necessary to operate the system. Each ice detector has a sensing probe
R which vibrates in the air. If ice formation occurs on the probe, the
R frequency of the vibration decreases. When the vibration decreases, the
R detector sends a warning to the ECAM.
R
R After a detection, the detectors are electrically heated to remove the
R ice. They are then ready to make another detection.
R
R Two levels of detection are provided:
R - one level gives elementary detections and is used to generate the
