(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 polybutylene (PB) to Class S of BS 7291-2:2006
or cross linked polyethylene (PE-X) to Class S of BS7291-3:2006; and (d)
be continuously marked with a warning that no sanitary appliances should be
connected to the pipe.

Note:
1. Plastic pipes should be joined and assembled with fittings appropriate to the
circumstances in which they are used as set out in BS EN ISO 1043-1.
2. Where pipes cannot be connected to the stack it may be possible to route a
dedicated
pipe alongside or in close proximity to the discharge stack.
Termination of discharge pipe
3.61 The discharge pipe (D2) from the tundish should terminate in a safe place
where there is no risk to persons in the vicinity of the discharge.
3.62 Examples of acceptable discharge arrangements are:
(a) to a trapped gully with the end of the pipe below a fixed grating and above
the water seal;
(b) downward discharges at low level; i.e. up to 100mm above external surfaces
such as car parks, hard standings, grassed areas etc. are acceptable providing
that a wire cage or similar guard is positioned to prevent contact, whilst
maintaining visibility; and
(c) discharges at high level: e.g. into a metal hopper and metal downpipe
with the end of the discharge pipe clearly visible or onto a roof capable of
withstanding high temperature discharges of water and 3m from any plastic
guttering system that would collect such discharges.
