I want to know what kind of septic system uses 3" pipe!
What's so unusual about 3" pipe for a septic system? 4" from the house to the first tank (we have 3 seperate tanks), 3" between the tanks and from the tanks to the leach field and 3" perf in the leach field.
Just courious, what do they use in your area?
