Connecting the wastewater outlet into your HomeBiogas system
3
Option 1 (Recommended):
Toilet discharge elbow should be at least 1m higher than the top of fertilizer
outlet (where wastewater pipe enters system)
up to 10m/33ft
≥1m
≤1.2m
up to 5m/16ft
Option 2:
Toilet level with Homebiogas system (toilet cannot be lower than system base)
The vented loop next to the toilet must be
less than 1.2m above
the toilet discharge elbow, and positioned
higher
than the
vented loop at the system.
There are 2 ways to connect the toilet to your Homebiogas system, depending on the location of your toilet and system.
We recommend using option 1 where possible, with the toilet placed higher than the system.
If option 1 is not possible, install the 2nd vented loop (included in the box) at a higher point than the fertilizer outlet.
The toilet-system connecting waste pipe should be as short as possible, maintain a downward slope toward the
system (no upward angles) and free from kinks and free from (u-shaped/up-and-down) bends.
Parts & Tools:
• 2m 38mmø flexible pipe (vented loop attached)
• 38mmø flexible pipe (length according to toilet location) -
not included in kit - need to purchase
• 38mmø steel hose clamps
• stabilizing cord
• screwdriver (flat)
1. Measure and cut the length(s) of pipe needed to
connect your toilet and the system. Refer to the
diagrams for vented loop positions if needed.
Note:
Discharge pipe should be kept to the minimum
necessary length. Avoid any kinks, dips or bends in
the pipe - maintain a suitably large bend radius in
the pipe and keep the pipe at a downward slope
towards the Homebiogas system.
