installation
ii) Connecting into the waste system of the building such as a
washing maching or sink trap. The connection must be
upstream of the washing machine/sink. If the connection
is down stream of if the waste trap then an additional trap
giving a minimum water seal of 75mm and an air break must be
incorporated in the pipe run, as above.
iii) Terminating into a gully, below the grid level but above the
water level
iv) Into a soakaway
Note: If any condensate pipework is to be installed externally
then it should be kept to a minimum and be insulated with a
waterproof insulation and have a continuous fall. The total length
of external pipe used should not exceed 3 metres.
Some examples of the type of condensate terminations can be
found below.
1. Internal termination of codensate drainage pipe to internal
stack.
. External terminaton of condensate drainage pipe via internal
discharge branch (e.g. sink waste) and condensate siphon.
3. External termination of condensate drainage pipe via internal
discharge branch (e.g. sink waste - proprietary fitting).
4. External termination of condensate drainage pipe via
condensate siphon
