pod irrigation installation
(cont.)
If more than 25 pods are connected to any one
zone, the greywater distribution will not be
uniform across all pods. Do not install fewer
than 15 pods to any zone as greywater may
enter the
H

grO
at a rate faster than the pump
can distribute it. Over time this may cause your
pump to fail.
Larger gardens require more than one zone of
irrigation. The automatic
H

grO
has four zone
outlets available but the manual
H

grO
should
incorporate a simple distribution manifold,
fitted with in-line valves, to allow individual
zones to be selected for irrigation.
Run 25mm purple

irrigation pipe from

unit or manifold, to the most distant
point in your pod zones and plug the far ends
with 25mm barbed in-line valves, secured
with ratchet clips. The valves allow the
pipelines to be opened for flushing during
annual maintenance. 25mm purple

pipelines should be buried under the soil or
concealed beneath a thick layer of garden
mulch.
installing the pods:
Using a hole punch, make a hole in the
25mm purple
H

grO
irrigation pipe and
connect the pod’s 6mm flexible tube using
the joiner supplied. The 6mm tube may be
shortened if desired.
In the desired position, bury an
H

grO
pod
upright with its 6mm flexible tube attached
and cover with soil. Provided the top of
the pod is covered with soil, its height will
ensure the greywater is dispersed at least
100mm below ground level.
Repeat this process until all your pods have been installed.

this will cause permanent damage to the pump.
