1.5 Condensate Drain
A plastic drain pipe must 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 7.3
for more detail.
