Where a single common discharge pipe serves more than one system, it should be at
least one pipe size larger than the largest individual discharge pipe (D2) to be
connected.
The discharge pipe should not be connected to a soil discharge stack unless it can be
demonstrated that the soil discharge stack is capable of safely withstanding
temperatures of the water discharged, in which case it should:
a) Contain a mechanical seal, not incorporating a water trap, which allows water into
the branch pipe without allowing foul air from the drain to be ventilated through the
tundish;
b) Be a separate branch pipe with no sanitary appliances connected to it;
c) If plastic pipes are used as branch pipes carrying discharge from a safety device
they should be either Polybutalene (PB) to Class S of BS 7291–2:2006 or cross linked
polyethylene (PE-X) to Class S of BS 7291–2:2006; and
d) Be continuously marked with a warning that no sanitary appliances should be
connected to the pipe.
