ALTERNATIVE DISCHARGE

Discharge at high level, i.e. into a metal hopper and

metal down pipe with the end of the discharge pipe

clearly visible (tundish visible or not) or onto a roof

capable of withstanding high temperature discharges

of water and 3m from any plastics guttering system

that would collect such discharges (tundish visible).

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 6 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. For further

information contact your Building Control Office or

The British Board of Agrément.
