Waste cannot go down inlet pipe
when feeding
System is producing bad odors
Solid waste is blocking the sink drain or a build-
up of waste below the sink drain is preventing
the feeding of waste.
The fertilizer drain pipe may be clogged at the
fertilizer outlet.
No flow of fertilizer from the
Overflow pipe, and high water
level in the sink
Open the fertilizer outlet cover, and check for any
blockages caused by an accumulation of floating
material. Dislodge the blockage with water and a
suitable tool.
Try to push down the blockage with the plunger.
This can also be done using a wooden broomstick
or long object to gently push the blocking matter
into the digester tank, while running water into the
sink to help clear the blocked matter.
1. Sink may not be properly sealed by plunger.
Make sure the plunger is turned 180° after inserting
it fully, so that the sink is sealed and smells cannot
escape. If the plunger still floats upwards, you may
need to weigh it down with a rock/other heavy object.
2. Bad smell when gas is used.
Remove the gas outlet (G) cap, pull out the Gas Filter
and check that the filter’s rubber seal is in place,
fitted into the filter’s lip. (Replace the filter with a light
downward push for a good seal)
If the rubber seal is fine, your filter should be replaced.
Contact Homebiogas or your local distributor for a
replacement.
3. Fertilizer smells bad.
It is normal for the system’s liquid to have a mild
fermenting/’organic’ smell from the broken down
waste (depending on what the system is fed) - the
smell is usually detectable only when feeding the
system or handling the fertilizer.
If you find this smell unpleasant, you can use
a container with a small/enclosed opening for
the fertilizer outlet sleeve to collect the fertilizer.
Alternatively, you can pass the fertilizer through wood
chips with a 2” pipe to eliminate the smell.
However, if the fertilizer smells abnormally bad, refer
to option 3.
4. Digester tank liquid smells bad.
The pH of the system could be low (a joint symptom
is poor gas flammability). Check the pH of the system
and add manure if necessary (refer page 41)
