Taps are in regular use, so I assume they are not dry. Maybe relation to the septic pump is just coincidental. Or, do I need to check (or have someone check, more likely) the stack? Maybe opening the septic tank altered airflow in the stack in some way that caused some debris already there to resettle in a fashion that causes a blockage(?) I'm not really suggesting, because I know nothing about plumbing. I'm just asking.
