1.7 Condensate Drain
A plastic drain pipe may need to be fitted to allow discharge of
condensate to a drain.
Condensate should, if possible, be discharged into the internal
household draining system. If this is not practical, discharge can
be made externally into the household drainage system or a
purpose designed soak away, see section 4.11 for more details.
