Service frequency of the effluent filter is based on each household’s wastewater generation habits. Some households may be able to go three years between service events and some might be monthly. It will be trial and error for the individual property owners to see what works for them.
Effluent filter alarms are available for people who are interested in that extra degree of security for that “just in case” event of sewage backing up into the basement when the effluent filter is clogged. A clogged filter will restrict the amount of wastewater leaving the septic tank, which causes the wastewater level to rise in the septic tank.
When the wastewater level rises above its normal flow level it will begin to back up into the piping network coming from the structure.
