– 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 discharging 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, or disabled people), consideration should be given to the installation of an electrically
operated device to warn when discharge takes place.
WARNING:
The discharge will consist of scalding water and steam. Asphalt, roofing felt and nonmetallic
rainwater goods may be damaged by such discharges.
