Care and Maintenance
This system
is pressurized by a sewage pump. The pump sends effluent to the drainfield
a minimum of 3 times a day with resting periods in between to allow aerobic
treatment of the effluent. If the pump or float system should fail, the
alarm will turn on signaling the failure. Contact a wastehauler to pump
the septic tank and the dosing chamber. Then contact your installer to
inspect and correct the problem. The alarm panel should be checked and tested regularly. Pump maintenance should follow
the manufacturer's recommendations. A properly designed and constructed
system should operate satisfactorily with care and routine maintenance
as described in this brochure.
