Waste pipe connection
 Figure 32
Alternatively if the first option is not possible an internal kitchen,
bathroom or washing machine waste pipe etc. can be used.
Ensure that the condensate drain pipe is connected "down stream" of
the waste trap and that the condensate drain enters into the top of the
pipe using a swept tee.

Where direct connection to "gravity discharge" pipework is not
physically possible, or where very long internal runs would be required to
reach a suitable discharge point, condensate should be removed using a
proprietary condensate pump, of a specification recommended by the
condensate pump manufacturer.
• The pump outlet should discharge to a suitable "gravity discharge"
outlet.
– The condensate then flows, by gravity, through the 22mm plastic
pipe to the condensate discharge point.
