Here is the back-filled tank lid. Notice how sandy this job was. There is also a “snifter valve” installed to allow drain-back.By code, a 4″ cleanout must be installed within 5′ of the home, at or above grade. Here are the 2 tanks and alarm, back-filled. Notice the alarm. The Counties prefer the alarms at the tank location now; vs. in the basement or garage.Here is a shot of the NDDS leach field.
