The drainfield stays happiest when the water that flows into it sits in the tank long enough for lots of solids to settle to the bottom of the tank and stay there. None of the back to back laundries that some womenfolk love when they get on the cleaning horse and ride like there's no tomorrow, running down all too slow or stupid to get out of their way as they gallop towards some bright and sparkling world where they drink mimosas and talk about starched sheets with well groomed young men dressed in tight whites with earrings.
It SHOULD be a baffled tank, and if so, that should not be an issue.
