5.2.6.1 High-level drain
Installing the highest drain is permitted as long as this does
not present a danger to anyone in or outside the building at
the drain point. Examples of points to consider when decid-
ing whether a location is suitable for the highest drain:
–
The possibility (taking the wind into account) that a per-
son might stay in the area where the water is drained
for a prolonged period of time, and, if this is the case,
whether the water is sufficiently cooled by that point to
pose no danger. The thermal conductivity of the material
surfaces, the climatic conditions, the installation location
and the drain pipework direction can, to different extents,
contribute to reducing the temperature of the water that is
being drained.
–
The position of the windows and other openings.
–
The probability of prams being under the drain opening.
–
The resistance of the surface to hot water.
–
The possibility of ice forming if water drains onto access
paths.
