Step and Grinder systems rely on power to operate the pumps.In the event of a power outage the pumps will not operate and effluent levels in the tank will increase with use. In the event of a power outage, please limit yourself to “light” usage of the system. It is recommended that you do not use the washing machine, dishwasher or take baths and or extended showers. Most systems will have a limited amount of reserve or emergency storage. But, extended use during a power outage could cause a sewer backup.For more information, please see the STEP or Grinder System Resources pages.
