TROUBLESHOOTING

Process failure 

Process failure from oxygen starvation of the biomass: 

If the biomass is starved of oxygen, the typical odours associated with anaerobic 
bacterial treatment will be noticed. This is caused by insufficient air flow into the 
biological zone. A blockage in the air line or blower is the most probable cause. 
a)    The inlet screens have been located on each end of the blower housing. If one 

screen becomes blocked by debris, the opposite screen should still be sufficient. 
The suggested routine preventative maintenance calls for brushing off the screen 
as needed. The configuration of the inlet screens and the required maintenance 
will protect the unit from oxygen starvation due to insufficient air flow.

b)    The blower is equipped with an inlet air filter. If this filter becomes blocked with 

debris, it could cause oxygen starvation of the biomass. The blower inlet filter 
should be checked every 6 months and replaced as needed.

Visual evaluation 

Wastewater backup is characterised by wastewater flowing back into the house or 
slow movement of wastewater in the drains. This may indicate a problem with your 
wastewater treatment system unit. Identify where the backup is occurring within your 
plumbing system. If you cannot locate material blocking the drain contact your service 
provider.

No use for an extended period

The Oasis Series 3000 Wastewater Treatment System will function normally even if 
wastewater does not enter the system for 5 days. 
The power to the system should be left on during short periods when there is no 
wastewater flow to the system. If the system will not be used for several months or 
longer, you should contact your service provider so the system can be checked for 
proper operation and serviced if necessary. A slight odour may be detected for a few 
days while the system returns to normal operation.
