Hello. When I checked the septic level when we got to the cabin it was at least 2 feet below the inlet. When I checked it when we left it picked up about a foot. There were six adults for three nights using the toilet and getting showers. There is no odor coming from the septic. Before we got the genie (and had no shower or toilet) the water level was at the inlet level and we had to syphon some of the top water. Since we installed the genie we never had to top off any of the water. I was just trying to tell what the normal level should be. We all appreciate your advice.
