• Where a single pipe serves a number of discharges, such as in blocks of flats, the number
served should be limited to not more than six systems so that any installation can be traced
reasonably easily. The single common discharge pipe should be at least one pipe size larger
than the largest individual discharge pipe to be connected. If unvented hot water storage
systems are installed where discharges from safety devices may not be apparent i.e. in
dwellings occupied by blind, infirm or disabled people, consideration should be given to the
installation of an electronically operated device to warn when discharge takes place.
Note: The discharge will consist of scalding water and steam. Asphalt, roofing felt and
non-metallic rainwater goods may be damaged by such discharges.
Note: It is not acceptable to discharge straight into a soil pipe. See G3 3.60 for guidance.
